Regional Aspects of Economic Geology (North America-South America-Africa-Australia)

NORTH AMERICA

Major geological unit:
a. North American (Canadian) Shield (Precambrian)
b. Appalachian orogeny (paleozoic)
  - Mineralization in Paleozoic orogens (Pb/Zn)
c. North american cordillera (Mesozoic-cenozoic)
d. North American platform

a. North American (Canadian) Shield (Precambrian)

- Consolidation of Archean nuclei (2,7-2,5 Ga)
- Late Archean to early Proterozoic basic and ultrabasic (2,6 Ga)
- Hudsonian/ Penokean orogeny (1,9-1,75 Ga)
- Paleoproterozoic sediments (e.g. Huronian supergroup)
- Sudbury impact (1,85 Ga)
- Anorogenic orogeny (1,6-1,2 Ga)
- Greenvillian orogeny (1 Ga) 

A. Consolidation of Archean Nuclei Deposit:
- stratiform massive Zn-Cu sulphides (VMS)
--> ore types: massive, laminated, breccia, stringer-type
ex. Abitibi belt : Kidd Creek deposit (hydrothermal black smoker) Kidd Creek is source of indium
- Orogenic gold ex. Ontario (Porcupine district, Hemlo)
- Archean BIF (syn-genetic)
ex. Homestake type (commonly located along the contacts of ultrabasic-basic volcanic rock to sediments)
ex. Algoma type (keypoints: associated with submarine volcanic rock, siderite-hematite BIF, less-extensive than superior type)
- BIF-superior type --> up to 200 m (chemical carbonate sediments)
=iron ranges related with Dulluth gabbro (Cuyuna, stromatolitic), Biwabik Iron Formation
=textures in Superior BIF
==Cherty (oxide facies, shallow water, thick bedded, granular, massive)
==Slaty (carbonate-silicate facies, deep water, thin bedded, non-granular, laminated)
- Ni,Cu (sulphides) --> in komatiite rocks within greenstone belts
- Rare-element pegmatites Sudbury district: Ni up to 50% world production

B. Mineralization in paleoproterozoic (1,9 Hudson orogeny- Churchill province-Transhudson orogen) -massive polymetallic
-uranium/Ag in Great Bear Lake

 C. Sudbury complex (1.85 Ga)
- meteorite impact, almost near to the mantle, resulted in the lake of magma
= stratigraphy from top to the bottom:
a. Post-impact sedimentary rock (top)
b. Suevite (Onaping sediment)
c. Impact-melt layer (granophyre - quartz gabbro - norite)
d. Brecciated crater floor (bottom)
== differentiation of layered complex
== formation of Ni-Cu-PGE mineralization in sublayer and offset dikes

D. Mineralization in Middle Proterozoic clastic sedimentary basin: U, Cu, Ni
= native Cu
= sedimentary U
= thick clastic sediments, basalts and native Cu (Ni-Cu-Co Thompson,Voisey's, Duluth Complex)

ex. Brunsswick no.12
=Iron ores
=Asbestos (ophiolites from ultramafic rocks around Quebec, biggest in the world)
=Rare element (Li) pegmatites

b. Mineralization in the forelands of Paleozoic orogens: 

Pb-Zn (MVT)
=forebulge, basinal brines
=major exploration target: forebulge unconformities, syncollisional faults and strike slip zones

==metal-bearing fluids migrate towards the marginal zones of the orogenic foreland due to hydrostatic and thermal gradients, compaction of fine-grained basin sediments and squeezing-out of basinal brines (by tectonic pressure)

==uptake of hydrocarbons and metal precipitation along permeability, boundaries, mainly in carbonates

==ore minerals: galena, sphalerite (Ag-poor),fluorite,barite,pyrite,marcasite,chalcopyrite,siegenite, bravoite. Carbonate occur as a "pod" for sulphide

==hydrocarbons and coal

==uranium (roll-front and colorado type)

c. Mineralization in the North American Cordillera

- part of the global circum-Pacific belt (Cu,Mo,Au,Ag)
==Deposits in the Lower Precambrian (>2500 Ma) 

ex. Stillwater complex (Montana),

==Deposits in the Middle and Upper Proterozoic (1500-600 Ma)

ex. SEDEX

-PGE, chromite, layered ultramafic-mafic intrusion (44 km strike length), 2.7 Ga

==Deposits in the Paleozoic (Cambrian to Carboniferous)

ex. Red Dog (Alaska)

==Deposits in the Mesozoic

ex. Stratiform VMS in volcanic rocks, porphyry copper deposits, Juneau

ex. Orogenic: Juneau, Klondike

==Upper Paleogene to recent

Video 6 - Kecenya Replika Kapal Pengangkut Anggur Bangsa Romawi

Terletak di danau kota Neumagen Dhron, kapal Stella Noviomagi ini bukan kapal asli, melainkan replika dari kapal yang dibuat tahun 220 setelah masehi oleh bangsa Romawi. Replika dibuat karena kapal aslinya punya sejarah sebagai pengangkut produk anggur setempat. Apalagi, kota ini memang terkenal sebagai daerah penghasil anggur tertua di Jerman. Pengunjung boleh naik kapal saat hari libur, lho!

Hidup ini keras, Bung

Sarah-Kirk bla bla.. saya lupa nama lengkapnya. Afro, sepertinya dia yang memimpin kru swiss air di airport Zürich saat itu. Saya hanya transit sebentar untuk penerbangan berikutnya. Ketika saya datang untuk cek paspor dan tiket, dia meminta saya mengambil semua barang saya, mengambil tiket, dan saya diminta mengantri di sebuah kubikel berwarna hitam, "Please follow me."

Apes, cuma itu pikiran saya. Saya datang ke profesor saya, 

M:"I have to leave you for a moment, the woman right there asked me to go with her." 

P:"Why?" 

M:"I don't know yet."

Saya masuk ke kubikel berwarna gelap tidak jauh dari lokasi boarding, ruangannya terbuka, hanya tertutup saja dari luar. Sarah meminta saya duduk, di dalam seorang wanita sudah menunggu (berlogat India) meminta saya untuk menunggu petugas lain.

Datang laki-laki, berbaju security,  meminta saya melepas sepatu dan mengecek lengan, kantong celana sampai kaki. Nihil. Sarah-kirk juga tidak menemukan sesuatu yg aneh di tas dan kantong basoka berisi poster itu. Tapi saya tahu, mbak acha acha nehi-nehi mengambil sidik jari di alat elektronik saya, untuk dia cek di scanner di komputernya. Sepertinya nihil, Sarah-Kirk seperti memberi kode ke wanita India itu.

Saya diminta ke loket passport control, untuk ditanya apa tujuan saya, dimana menginap, kapan kembali ke Austria dsb, oleh petugas lainnya. Saya jawab apa adanya dan jujur, saya tanya balik dalam Jerman ke wanita itu mengapa saya diperiksa. Ketika saya tanya balik, kenapa saya di cek di kubikel itu, tidak ada jawaban, seperti pura-pura tidak mendengar. Saya ulang pertanyaan ke Sarah-Kirk. Nihil.

Profesor saya cuma bisa melihat dari jauh dan menanyakan "everythings fine?". Lewat kode tangan, saya cuma bisa menjawab geleng kepala dan angkat tangan tidak tahu.

Sarah-Kirk memberikan kembali tiket saya yang sebelumnya ditahan olehnya, dan di tiket sudah ada cap "security guard" berwarna kuning dan tulisan "HS" atau "4S", tulisannya besar tapi tak terbaca. Dia mencoret nama saya dari daftarnya, "Have a nice flight."

Bujubuset. Gitu doang.

P:"What happened?" 

M: "No explanation." Profesor saya mencoba mencairkan suasana, 

P:"Maybe you should buy a new family name, Schmidt, Meyer or anything you like. They randomly checked only from your family name."

Siiit...

Saya ambil positifnya. 3 dari ratusan penumpang menuju Montreal mendapat perlakuan ekstra, termasuk saya. Di kubikel yang sama, puluhan orang mengantri untuk keberangkatan ke Las Vegas, dan ketika saya tanya, mereka ga tahu untuk apa di cek disana. Mereka berpaspor Swiss, Jerman, dan beberapa dari Eropa Timur. nyway. Kalau memang itu gara-gara embel2 nama saya, ya sudah lah, "that's a life as a foreigner, as a minority." Suka ga suka, adil ga adil, seperti itu realitanya. 

Saya cuma bisa berdoa supaya diberi keselamatan dari Allah. Life is tough. 

At least masih dapat nasi goreng 5 langkah dari penginapan.

Iseng-iseng jadi jurnalis di TV Indonesia

Projek iseng-iseng Vidya (dan sedikit saya) buat mengisi waktu luang*. Bermodalkan kamera Nikon yang sudah cukup berumur dan diselotip sana-sini, alhamdulillah beberapa video kami di terima NET TV dan bisa tayang di NET Citizen Journalist. Lumayan, bisa buat nabung buat ganti kamera kalau nanti kamera Nikon ini sudah pensiun. Klik gambar untuk melihat videonya. Enjoy!

Video 1 - Ajak Anak Mengeksplorasi Air dan Alam di Pulau Buatan

Bisa menyusuri ilalang, bermain air di pancuran, hingga bermain pasir kerikil! Enggak cuma sebagai wahana bermain anak, arena publik ini juga bisa mengasah indera si kecil juga lho. Berbagai arena permainan air yang asyik ini terdapat di Wasserspielplatz di kota Wina, Austria. Kalau udah main di sini, anak-anak pasti dijamin betah deh!

Video 2 - Megahnya pegunungan Alpen bisa dinikmati dari sini

Ingin melihat indahnya pegunungan Alpen, cobalah berkunjung ke sini. Yup! Inilah Dachstein, salah satu puncak tertinggi pegunungan Alpen di Austria. Untuk mencapai puncaknya, kamu bisa coba naik gondola. Di sini kamu bisa menikmati pemandangan salju abadi dari jembatan gantung yang panjang. Wooow!

Video 3 - Hiking bersama buah hati 

Bingung mau ajak anak ke mana pas summer holiday kali ini? Ajak anak hiking bisa jadi pilihan. CJ Vidyasari merekomendasikan Pegunungan Alpen di kota Präbichl sebagai destinasinya. Lewat jalur yang paling pendek, bisa ajak si kecil nikmati pemandangan hutan pinus, menyusuri ilalang, dan melihat sapi yang sedang merumput. Pastinya perjalanan ini akan menjadi hiking ceria karena panorama Pegunungan Alpen luarr biasa indahnya apalagi ditempuh bersama keluarga!

Ini dia pesona Danau Gruener See, tempat wisata paling kece di Tragoess, Austria. Danaunya jernih dengan air yang kehijauan. Air danaunya berasal dari lelehan salju pegunungan Hochschwab, Alpen, jadi sebening kristal deh! Keindahan danau ini dijamin bikin kamu betah duduk atau bermain di tepi danau. Bisa juga lihat bebek atau angsa liar yang mencari makan di danau.

Video 9 - Memotret Château Frontenac di Kota Tua Quebec Kanada
Ini lho gedung hotel mewah yang paling banyak di foto di dunia, namanya Château Frontenac. Hotel ini dibangun sejak akhir abad ke-17 dan mempunyai 600 kamar dengan 18 lantai. Hotel ini berlokasi di tepi sungai St. Lawrence dan terletak di atas bukit di kota Quebec, Kanada. Di Quebec kita juga bisa melihat arsitektur Notre Dame Des Victoires yang merupakan sebuah gereja tua. Indah banget ya!

July 17th, 2017. We packed our lunch, children carrier, water and took a bus at about 8.40 from Leoben Annaberg. The bus costs 4 Euro/ person, because we have zwei und mehr discount card (Steirische Familienpass), which allow reduced price (38%). Unfortunately, the OeBB Vorteilscard Family cannot be used oin Postbus. It tooks for about 40 minutes from Leoben to Praebichl. 

At around 9.30, we arrived at Praebichl bus stop. Although it is a summer time, the wind blows mildly. It was too cold for Vidya, so she tooks her jacket, but Aqila insisted that it was not cold. From the bus stop, we searched for the hiking route and Aqila, our 3 years old toddler was very excited. We followed the hiking signature "Erzwanderweg."

 

From there, the hiking trails was surrounded by high trees (pine?) and moss. Aqila can still manage and did not want to sit in the bike carrier. After 1 hours walked, she was tired and wants to sit in the bag. I was surprised that she could managed to hiked by herself. We took the shortest way to reach Polster from Praebichl, which means, the steepest route. After high trees, the scenery is more opened and we can saw the Polsterschutz huette. From that point, the route split into two. To the left is Polster and the other side is the "knappensteig" to Leobnerhuette. We took the left and no more high trees surrounding us. 

 It was 11.00, and Vidya got tired and was hungry. We decided to stop in a beton under the "sessellift", where scenery to Reichenstein, Erzberg and Kaiserschild are clearly be seen. Aqila was excited and I offered her pen and paper to draw. It was one hour break. Some other hiker was behind us, some brought their "flying bags" (i do not know how to say). 

It was 12.00, we continued until Polsterschutz huette. It tooks less than 1 hour and we met Ludwig, the owner of those huette. We ordered a cup of coffee and black tea. It was only 6 people on that huette. We were three, Ludwig and another couples above. Ludwig said, that the polster lift will be renovated soon. He seemed happy, because more people will come on winter, but he said, he cannot depending only from those huette. It was a hobby for pensionist, he said.

 

From huette, we continued our steps to Polster. In half an hour, we arrived at the top of Polster. Hurraaay, I celebrated my 29th birthday in Polster....

We stayed for about 20 minutes and enjoyed the scenery, and follow the routes into the Leobner huette, and tooked the zigzag trails until back to Praebichl. It was longer than I expected, and we arrived back at bus halte at 16.25. In totals, it tooks 6 hours of walked (1 hour Aqila walked by herself) and 5 hours in my bag. My shoulder was getting red, because then I realized that the bag was a little bit inclined. Anyway, I am pleased that Vidya, Aqila enjoyed this trip, and asked me "where will we hike after this?".  I just smiled to her.

I found my stolen bike!

22.07.2017

13.30: Me, Vidya and Aqila went to buy some stuff in a store. We park our bike side by side and lock it together.

15.40: We finished shopping. Unfortunately, someone opened the lock. Vidya's bike was lost and another bike was not locked.

15.42: I decided to report this cases to the local police officer.

15.43: I MET THE THIEF ON MY WAY TO POLICE OFFICE! +-20-25 years old guy riding Vidya's bike. He was trying his new bike and did not recognize me. I try to hit the bike and he run. I cannot hit him, unfortunately I felt down. He drove away using Vidya's bike.

15.44: I drove back and try to chased at the back of him. Fortunately, I can still see him, going through the main square, and so on, and he went to his apartment.

15.48: I was too late, the door is locked, but I am 100% sure that the thief has entered the apartment with Vidya's bike. I made an emergency call: 122 (Remember this number!:EURO emergency call).

15.55: Officer came, 2 cars, 4 officer (2 men, 2 women). They opened the door. I was waiting outside.

15.58: Officer asked me to come in. I found my bikeeeeee.....

15.58 - 17.00: I was interrogated in Police office. They were very kind and professional. The report will be submitted to the Justizezentrum Leoben (court). I HOPE THEY FOUND THE THIEF.

Thank you for quick response and cooperation. The officer said, locks with number combination were easy to be opened (although I know that my current lock is perfect-number combination, but then, after today, I changed my mind). They suggest to change with a locks+key.

Congratulations AmazonPrime, you have new customer for bike accessories. Anyway, thank you officer for quick response. Vielen Dank LPD (Landes Polizei Direktion) Leoben!

To Joel and Anung, I am sorry for this matter. I will make sure your bike is saved with me. Thank you for your trust.

Alhamdulillah, masih diberi kepercayaan dari Allah buat menjaga amanah. Barang dikunci saja bisa hilang, apalagi ga dikunci. Abus juga buatan manusia. Waspadalah, waspadalah!

18.45: article started

19.13: article finished

Abus is still man made. Nothing is perfect.
