چکیده
an increasing numbcr af biaxial reflectance indicatrixes arc being reported from coals of >arious ranks from around the world (Cook, et ul., 1972: Stone and Cook. 1979; Hower and Davis. 1981; Levlnc and Davis. 19841. The objective of this preliminary study was to examinc a variety of coals from the Peacc Kiver Coalfield to determine if any biaxial reflecting coals are present, and to dcvise a methodology ti) identify these coals from particle samples. As part of the study 1 3 oriented coxtl samples wcrc collected from various locations in the central and northern portions of the coalfield.

Washability Characteristics of British Columbia Coals
As part of the British Columbia Geological Survey Branch’s Coal Quality Pmject, washability characteristics of coals from all parts of the province are being compiled (see manuscript S-l, this volume, for descriptions of other ongoing coul quality studies). The interpretation of these data will provide insight into the geological basis of washability. and hopefully provide practical information...
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 کاملMajor and Trace Element Geochemistry of Coals and Intra-Seam Claystones from the Songzao Coalfield, SW China
Silicic, mafic and alkali intra-seam tonsteins have been known from SW China for a number of years. This paper reports on the geochemical compositions of coals and tonsteins from three seam sections of the Songzao Coalfield, SW China, and evaluates the geological factors responsible for the chemical characteristics of the coal seams, with emphasis on the influence from different types of volcan...
متن کاملPeroxy Complex and Crossing Point Temperature of Talcher Coals - An Adducer to Assess the Spontaneous Combustibility Character
Spontaneous combustibility character of the Talcher coals has been measured in terms of peroxy complex and crossing point temperature. Coal samples collected from the two horizons i.e. Karharbari Formation and Barakar Formation were separately studied and the values measured for the aforesaid parameters were recorded. It was found that the coals of this coalfield are highly prone to spontaneous...
متن کاملGeol Fldwk-01.vp
There are two major coal-bearing formations in the Peace River Coalfield in northeastern British Columbia, The Gates and the Gething. The younger Gates Formation hosts to the two major coal mines that have operated in the area; therefore there is some coalbed methane (CBM) information available for the formation. In contrast there is very little CBM information available for the older Gething F...
