Alexei Rukhlov; Yao Cui — 2014-12-15 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, released as BCGS GeoFile 2016-04, is populated with data compiled from 214 BCGS publications released between 1986 and 2015. It includes 10,914 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. https://www2.gov.bc.ca/gov/content?id=1AAACC9C65754E4D89A118B875E0FBDA

Alexei Rukhlov; Yao Cui — 2011-03-09 The joint federal-provincial Regional Geochemical Surveys (RGS) have been carried out in British Columbia since 1976 as part of the National Geochemical Reconnaissance (NGR) program to aid exploration and development of mineral resources. The British Columbia Geological Survey maintains provincial geochemical databases capturing information from multi-media surveys. This 2017 release is the most current index of 73 regional geochemical survey areas, represented by 112 publications, covering about 80 percent of the province. Results of the surveys are presented in the 2017 RGS Database, with 64,828 samples and about 5 million determinations analyzed using 18 methods in 18 laboratories. This database is published as BCGS GeoFile 2017-11. https://www2.gov.bc.ca/gov/content?id=1AAACC9C65754E4D89A118B875E0FBDA

Alexei Rukhlov; Yao Cui — 2014-12-16 In parts of British Columbia where topography is subdued, surface drainage is poor and there is an abundance of lakes, lake sediment and water surveys are a valuable exploration tool for delineating regional geochemical patterns and detecting anomalous metal concentrations related to mineral occurrences. https://www2.gov.bc.ca/gov/content?id=1AAACC9C65754E4D89A118B875E0FBDA

Alexei Rukhlov; Yao Cui — 2014-12-16 Stream water samples are collected as part of the Regional Geochemical Survey (RGS) program, which covers over 80% of British Columbia. An additional 4332 stream and lake water samples were analyzed by ICP-MS, ICP-ES and other methods for trace and minor elements in NTS map areas 082M, 093C/D/F/K/L/M, 094L/M, 103A, 104A/H/J/P. The data provides the elements found in the water sample as well as the test method, the detection limit and the original source. The data is available for download and viewing at the BC Geological Survey website. https://www2.gov.bc.ca/gov/content?id=A519A56BC2BF44E4A008B33FCF527F61

Alexei Rukhlov; Yao Cui — 2011-03-09 2020 DATABASE (Excel): The joint federal-provincial Regional Geochemical Surveys (RGS) have been carried out in British Columbia since 1976 as part of the National Geochemical Reconnaissance (NGR) program to aid exploration and development of mineral resources. The British Columbia Geological Survey (BCGS) maintains provincial geochemical databases capturing information from multi-media surveys. This 2020 release of the most current and complete province-wide geochemical data set collected under the (RGS) program. The database was compiled from 116 original sources with 65,429 samples and about 5 million determinations analyzed using 18 methods in 18 laboratories. This release augments the database with new RGS data compiled from BCGS and Geoscience BC publications between 2016 and 2019. Compared with the data in the last release, data in this release have been given further quality control treatment and revision. For the ease of use and consistency with previously published data, the data set was generated from the RGS database in a flat tabular format. The 2020 data set, released as BCGS GeoGile 2020-08, is presented in two MS Excel files, ‘RGS2020_ data.xlsx’ and ‘RGS2020_metadata.xlsx’. The data tables capture locations, field observations, analytical results and laboratories, and geology underlying sample sites for stream-, lake- and moss-sediment, water and lake samples, heavy mineral concentrates, tree twig, and needle ash. The analytical determinations include up to 63 analytes from sediment samples and up to 78 analytes from water samples. These samples, collected at an average density of about 1 site per 7–13 km2, provide representative geochemical data for the catchment basin upstream from the sample site. The RGS currently covers approximately 80 percent of the province. https://www2.gov.bc.ca/gov/content?id=A519A56BC2BF44E4A008B33FCF527F61
