Tonsteins : Possible Stratigraphic Correlation Aids in East Kootenay
نویسنده
چکیده
The term 'tonstein' does not, strictly speaking, imply any particular mode of formation. Much recent work suggests that many tonsteins are the end product of the reworking andlor alteration of volcanic ash lfor example, Price and Duff, 1969; also see paper by Kilby, this volume). Work i s a t present too preliminary to allow genetic classification of the samples from southeast British Columbia discussed here.

متن کاملMaceral Affinity of Phosphorus in Coals from the Elk Valley Coalfield, British Columbia
British Columbia exports about 25 million tonnes per year of metallurgical coal from two coalfields, which follow the Rocky Mountains along the eastern edge of the Province. In the north there are two mines in the Peace River coal&Id and in the south, five mines in the east Kootenay coalfields (Figure I). The east Kootenay coalfields are divided into the Elk Valley, Crowsnest and Flathead field...
متن کاملGEOLOGICAL MAPPING OF THE YAHK MAP AREA, SOUTHEASTERN BRITISH COLUMBIA: AN UPDATE (82Fll)
This article summarizes new findings of the East Kootenay project after completion of 2 months of fieldwork in the Yahk map area (82F/I) in 1994. The project was initiated in 1993 to provide 130 000-scale geological maps with improved stratigraphic correlations, and to stimulate base metal exploration southwest of the Sullivan mine. Work in 1994 focused on fill-in traverses and measured sect...
متن کاملMassive Sulphide Deposits of the Eagle Bay Assemblage , Adams Plateau , South Central British Columbia ( 082
The Eagle Bay assemblage in south central British Columbia contains numerous polymetallic massive sulphide deposits, mainly within highly deformed and metamorphosed Devonian felsic volcanic rocks. A number of these, including Rea and Homestake, have had limited past production, and others have undergone extensive exploration and development. Less known and understood are the sediment-hosted mas...
متن کاملComparing ordinary kriging and advanced inverse distance squared methods based on estimating coal deposits; case study: East-Parvadeh deposit, central Iran
Finding a proper estimation method for ore resources/reserves is important in mining engineering. The aim of this work is to compare the Ordinary Kriging (OK) and Advanced Inverse Distance Squared (AIDS) methods based on the correlation between the raw and estimated data in the East-Parvadeh coal deposit, central Iran. The variograms and anisotropic ellipsoids are calculated to estimate the ash...
