Abstract
This report summarizes the results of the Narragansett Basin Project activities investigated by the Bureau of Mines. Since 1976, 28 drillholes have yielded 20,000 ft of core. Results show that the basin is complexly folded and faulted and variably metamorphosed. The northern two-thirds of the basin is less deformed and metamorphosed than the southern third. The deformational model that explains the data and that will guide future drilling holds that coal has been mobilized during deformation and concentrated in the crests and troughs of folds as greatly thickened pods and lenses. About 60 pct of the 28 holes have encountered coal over 10 ft thick and seams up to 20 ft have been mined in this century. The coal is low-sulfur, high-ash anthracite. Mapping of surficial geological and societal factors important to potential mining has been done and a computerized mapping capability of the basin of 1 sq mi grid was developed based on weighting values of geologic and nongeological factors.
