    New British Columbia lithogeochemical database: Development and preliminary data release

    Tian Han, Alexei S. Rukhlov, Mustafa Naziri, and Adrienne Moy



    A new database system was developed to maintain, update, and manage province-wide lithogeochemical data collected by British Columbia Geological Survey (BCGS) geoscientists and their research partners. The database is populated with data compiled from 214 BCGS publications released between 1986 and 2015. It includes ~11,000 samples with about 250,000 determinations analyzed by 26 analytical methods in 21 laboratories. The database operates through a semi-automated process for data compilation, quality control, upload, and product generation, which helps provide consistent, standardized, and long-term data storage and update, and regular release. The data product derived from the database provided in this release is in a user-friendly format (CVS), which can be easily brought into GIS and geochemical data evaluation software for visualization and analysis.

    Project Highlight

    Mapping a potential new metallogenic epoch in the Canadian Cordillera

     

    This past summer, a team of BC Geological Survey geologists spent two months southeast of Dease Lake mapping rocks in the upper part of the Hazelton Group. Led by Bram van Straaten, the team focused on documenting the internal stratigraphy and regional extent the Horn Mountain Formation, a late Early to early Middle Jurassic volcanic succession, and establishing its connection to local porphyry copper occurrences. They discovered that this previously enigmatic unit continues along strike for at least 55 km, with lower subaqueous and upper subaerial subunits, and that early-stage exploration projects in Middle Jurassic porphyries, including the Tanzilla prospect and McBride showing, may represent a new metallogenic epoch in the Canadian Cordillera.

     

    A fresh face for MapPlace

     

      

    MapPlace 2 is a web service created by the British Columbia Geological Survey that allows anyone with an Internet connection to efficiently mine multiple geoscience databases. In contrast to similar services, MapPlace 2 goes beyond simply displaying information. Databases are continuously updated and talk to each other, enabling users to conduct queries and generate custom results by connecting to current data from many sources. Relative to the original version, MapPlace 2 requires no plug-ins, is faster, handles larger datasets, accesses third-party base maps and imagery and, with a simpler more intuitive interface, is easier to use.
     
    The BCGS invites you to attend the MapPlace 2 beta workshop at the BCGS Open House November 17-18, 2016 in Victoria, BC.

    Out and about

    In August, Travis Ferbey helped lead Simon Fraser University’s third-year field school, guiding students through the Quaternary geology of the Cowichan Valley and teaching surficial geology mapping methods.

     

    In April, JoAnne Nelson, Lawrence Aspler, and Adrian Hickin gave Friends of Uplands Park, a local naturalist group in Victoria, a tour of Cattle Point, highlighting the bedrock and Quaternary geology exposed on the eastern side of Victoria.
     

     

    In October, Larry Jones, Yao Cui, and Gabe Fortin delivered a presentation MapPlace 2 to the Vancouver Island Exploration Group in Nanaimo.

    In October, Travis Ferbey and Adrian Hickin introduced students and faculty from the University of the Fraser Valley to the BCGS and spoke on how knowledge of Quaternary geology is applied to solving geologic problems.

     

    In March Luke Ootes, gave a talk about the Slave craton and its Proterozoic borderlands at Simon Fraser University. In October, he spoke to the Vancouver Kimberlite Cluster about how Archean and Paleoproteroic events along the western margin of the Slave craton influenced On-craton diamonds.

     

    The women of the BCGS took to the walls at the CragX Climbing Centre in Victoria to test out their skills on a different kind of rock slab.

    Geoscientist Snapshot

     

    Yao Cui leads the BCGS geospatial group, which works on processing, integrating, managing, producing, and delivering geoscience data. One of Yao’s main responsibilities is the provincial digital geology database and map. In order to streamline integrating maps into the database, Yao developed the Geospatial Frame Data (GFD) model. Yao is also the lead on developing the new MapPlace 2 web service.


     

     


    In recent years, JoAnne Nelson has examined the tectonic setting of porphyry and related systems in northwestern Stikinia, focussing on the structural framework of these deposits and their temporal relationship to episodes of arc reconfiguration. In 2013-2014 JoAnne worked in the KSM-Brucejack-Treaty Glacier and Snip-Bronson-KSP areas, finding evidence that the deposits are localized along reactivated basement faults within in few km of a latest Triassic to Early Jurassic unconformity at the base of the Hazelton Group. This unconformity marks when the arc magmatism recorded by the Stuhini Group ended, and also marks when renewed arc activity, represented by basal Hazelton units, began. In 2016, JoAnne took the study one step further, investigating the deepest structural levels exposed in Stikinia. Exposures of and evidence for the deepest rocks of Stikinia lie in the western part of the terrane, along a transect between Terrace and Prince Rupert, and west of the old Anyox mine. The project aims to explore the basement to Stikinia, where it originated, and the relationship between deep-level magma chambers and porphyry deposits.

     

     

     

     





    The BCGS welcomes Gabe Fortin who joined the BCGS in September 2016 as a Geomatics Geoscientist. Gabe is working with the Resource Information Section on producing and delivering geoscience data through the MapPlace web service.

     














    The BCGS welcomes Dejan Milidragovic who joined the BCGS in November 2016. Dejan is working with the Cordilleran Geoscience Section and is responsible for field mapping and mineral deposit studies with particular focus on nickel mineralization.
