Western Tethyan Metallogeny Project Update

MDRU’s Western Tethyan Metallogeny Project is well into its second year! This is our largest research project and is supported by a consortium of 15 industry sponsors, who are supporting 20 students and researchers working across 10 countries.

Project highlights to date include technical meetings in Çanakkale and Izmir, both in western Turkey, and related field trips. Well into the data compilation phase, new GIS products and geochemical, geochronological and geophysical datasets are being developed. Students have been fully engaged in petrographic and spectrometric characterizations of host rocks, ore and alteration mineralogy from various deposits and study areas along the west-central Tethyan orogen.

On the GIS front, the project recently acquired geospatial data for Azerbaijan, Georgia and NE Iraq while the final steps are being made in the process of acquisition of digitized dataset for Romania. Geochronological GIS layers for Serbia, Macedonia and Bulgaria as well as Romania, Greece and the Lesser Caucasus were released to project sponsor in early 2014. Release of the complementing whole-rock geochemical coverage is the next project deliverable.

A summary of student research projects are outlined below:

  • Fabien Rabayrol’s PhD thesis aims to unravel the complex and diverse metallogeny of central Anatolia in the context Western Tethyan tectonic evolution. Fabien generated a unified tectonic map of Turkey which includes all of its exotic terranes and regional structures. He defined metallogenic districts on which to focus his 2014 field work.
  • PhD candidate Dragan Dragić has been actively engaged on reprocessing geological and metallogenic maps of Serbia into a seamless GIS format.
  • Graham Leroux (MSc) devised a new stratigraphic setting for the TV Tower epithermal Au district of the central Biga Peninsula in NW Turkey. Ore petrography, supported by scanning electron microscopy and focused on sulphide mineralization and related alteration at Kuçukdag is underway and was presented at Roundup on his poster entitled: Gold in the Biga Peninsula: A geological and structural map of TV Tower and Kirazli Epithermal Au-Ag +/- Cu, northwest Turkey.
  • Jelena Živanović (MSc) measured porosity and permeability of the sedimentary rocks from the Bigar Hill sediment-hosted Au deposit in eastern Serbia. Her 2014 Roundup poster was entitled: Metallogeny and Stratigraphy of Sedimentary Rock-Hosted Bigar Hill Gold Deposit, Western Timok, Serbia.
  • Raja Yarra (MSc) compiled and analyzed drill core and surface samples from the Armenian Shahumyan polymetallic deposit using shortwave infrared spectroscopy to characterize variability in chemistry of alteration envelopes. Raja’s Roundup poster is entitled: Vein Paragenesis and Alteration of the Shahumyan Polymetallic Vein-Hosted Epithermal Deposit, Kapan District SE Armenia.
  • Paula Brunetti’s (MSc) work on the Halilaga porphyry Cu-Au deposit focused on deciphering geochemical signatures of host intrusives and establishing alteration patterns associated with the mineralization. Paula's Roundup poster was entitled: Geology, Alteration and Mineral Paragenesis of the Halilağa Porphyry Cu-Au deposit, Biga Peninsula, NW Turkey.
  • Erde Bilir (MSc) examined the petrography of 60 rocks and followed up with SWIR determinations on the associated alteration assemblages, many will be followed up with zircon U-Pb geochronological analyses. Erde’s Roundup poster was entitled: The Early-Middle Eocene Magmatism and Related Epithermal Systems of the Eastern Turkish Pontides.
  • Kaleb Boucher (MSc) examined alteration envelopes of the Efemçukuru LS epithermal Au deposit near Izmir, Turkey using SWIR, and will update geology maps and structurally evaluate regional faults, foliations, vein and dike orientations. His Roundup poster was entitled: Structural and Vein Analysis of the Efemçukuru LS epithermal Gold Deposit, Western Turkey.

The 2014 Roundup meeting in Vancouver (January 2014) featured Western Tethyan Project Manager Alex Mišković’s summary of the exploration activities along the western Tethyan metallotect. A full MDRU Tethyan project update was delivered to the sponsors at PDAC in March 2014.

Yukon-Alaska Gold Metallogeny Project: Open for Sponsorship

Building on the successes of the recently completed Yukon Gold Project, MDRU has launched a new collaborative research project to provide metallogenic constraints on gold mineralization in poorly understood or exposed portions of Yukon and Alaska.

The mineral deposit studies and metallogenic frameworks that will be developed in this project will provide new and improved exploration and targeting models over this large and highly prospective region.

The project is being led by Murray Allan, with significant contributions from Jim Mortensen, Craig Hart, Matias Sanchez and Richard Goldfarb (USGS). The project will also include a PhD-level study on Kaminak Gold Corp.’s Coffee project, and at least two MSc-level deposit-related studies.

The project is still open to sponsorship. For more information, or to enquire about post-graduate opportunities, please contact Craig Hart (chart@eos.ubc.ca) and Murray Allan (mallan@eos.ubc.ca).

Bits and Bytes

Thomas Bissig will be overseeing two new MSc projects, beginning in 2014. The first, funded by NGex resources, will focus on their Los Helados prospect which contains porphyry Cu-Au mineralization hosted in Paleozoic granitoids and is centered on hydrothermal breccia body. The prospect is located between the El Indio and Maricunga Au belts along the Chile-Argentina border. This study will be important to understand the relationship of extrusive vs. intrusive magmatism to porphyry style mineral potential because volcanic rocks are scarce in the district and host rocks to mineralization are probably much older. The study site's location between two mineral belts will also allow delineating the extent of areas prospective for porphyry Au vs. high-sulfidation epithermal deposits.

The structural and tectonic setting of IOCG, porphyry Cu-Au and Kiruna type Fe deposits in Northern Chile will the focus of the second collaborative MSc study, funded by Mineria Activa. The study will be focused on 2 to 3 field areas in the Coastal IOCG Belt of Chile, and will aim to understand the main controls on the different styles of mineralization in this region.

Farhad Bouzari spent ten days in January with the Ph.D. prospective student, Esmail Heidari, in the Kerman region of Iran, examining various porphyry centers and host stratigraphy along the region.

Antonio Celis’ M.Sc. work during the last few months on PIMS has been focused on titanite in alkalic porphyry deposits. His studies on titanite, summarized in RoundUp poster, show various generations of titanite and recent microprobe analyses suggests distinct geochemical characteristics on magmatic and hydrothermal species.

Irene del Real’s M.Sc. research on Woodjam property, BC, characterized field and petrographic relationships of the Southeast Zone and Deerhorn porphyry centers and recently has been focused on geochemical signatures of the host intrusive units suggesting that magma mixing played a role in transition between alkalic and calc-alkalic environments.

Lauren Greenlaw presented her research to the Vancouver geochemistry working group on Feb 20, 2014. Her talk, entitled "The Lithogeochemical Footprint of the Relincho Cu-Mo Porphyry Deposit, Atacama Desert, Chile" was graciously hosted by Pim Van Geffen at Reflex Geochemistry on Georgia St. in downtown Vancouver.

 

Gruffudd Roberts, visiting student from UK, completes his Honours thesis at MDRU. Building on MDRU’s footprint study at Red Lake Gold Mines, Ontario, Gruffudd works on carbon and oxygen isotopic signature of carbonate alteration around the gold mineralization. His work shows that both pervasive and vein type carbonate alterations are isotopically zoned for several km and vectors towards the deposit.
