A REVIEW OF SULPHUR IN COAL: WITH SPECIFIC REFERENCE TO THE TELKWA DEPOSIT, NORTH-WESTERN BRITISH COLUMBIA
The Jura-Cretaceous coal seams of the Currier, Mist Mountain, &thing and Gates formations generally formed in delta or strand plain environments with little marine influence. The sulphur contents of coal from these formations is therefore generally low, nearly always less than I % and often less than 0.5 %. Coalbearing formations of the Cretaceous Nanaimo and Skeena groups were deposited in coastal areas with more marine influence. Consequently sulphur contents are more variable and tend to be higher. It is therefore important to study aspects of sulphur in Cretaceous coal seams such as the seams in the Skeena Group at Telkwa (Figure I).
POTENTIAL COAL AND COALBED METHANE RESOURCE OF THE TELKWA COALFIELD, CENTRAL BRITISH COLUMBIA (93L/11)
sampling and desorption testing of fresh coal samples obtained from companies conducting exploration throughout the province. In addition methane adsorption isotherm tests arc: performed on some samples. During the summer of 1992 a project was undertaken to test coal seams intersected in the ongoing Manalta Coal Limited drilling program in the Telkwa coalfield. On-sitc activities consisted of the collection and desorption 01 five samples. This report presents the desorption result!; and coal quality data for the five samples and thret: adsorption isotherms. The coal resource, the potmtial coalbed methane resource and reserve for the Telkwa coalfield are also discussed.
The succession above the soft bed and bassy mine in the pennine region
The measures between the Soft Bed and the Middle Band Coal of Yorkshire and the equivalents of these seams in Lancashire, the Bassy and Lower Foot Mines, are remarkably uniform. The horizons of two thin Lingula bands, first described by the author from Huddersfield, may be traced, usually as marine shale, northward to Bradford and Burnley, southward to near Sheffield, westward to St. Helens and south-westward to Goyt's Moss, Derbyshire, where the lower band has yielded Gastrioceras sp. The bands of Lingula divide the measures into three small-scale cyclic units of sedimentation which contain non-marine lamellibranchs throughout much of their vertical extent. 
 
 
 
Studies of faunas from localities which yielded the types of Carbonicola fallax, C. protea and C. haberghamensis Wright are described in some detail. At Feniscowles, near Darwen (type locality for the first two species) it is shown that with passage upward into slightly more coarse grained beds in the lower cyclic unit the small shells of the C. fallax group show an upward increase in H/L ratio with some evidence of a split into two species. 
 
 
 
The non-marine succession, of Honley, near Huddersfield, is regionally summarized. Attention is drawn to a maximum of Carbonicola rectilinearis Trueman and Weir in the lower part of the lower cyclic unit and to the marker horizons of Carbonicola discus Eagar and C. haberghamensis Wright in the upper part of the middle unit. 
 
 
 
Carbonicola pilleolum, the new species described, covers variants previously referred to, or compared with, C. sulcata (Brown).
