On the Structure of the Albion Coal-Measures, Nova Scotia

Abstract

T he Coal-measures of the Albion Mines present some features very different from those observed in other parts of the coal-formation in Nova Scotia. This must he very evident to any one who compares the published sections and descriptions of the coal-measures of the South Joggins and Sydney, and those of the Pictou coal-field by Mr. Logan, Sir C. Lyell, and Mr. Dawson. Unfortunately the natural sections at Pictou are so imperfect, that the order of succession of the beds is much less fully known than at the other places referred to. Recent exploratory works, conducted by Mr. Poole, Superintendent of the Albion Mines, have, however, brought out some important facts which are exhibited in the Plan and sectional lists appended to this paper, to which these remarks relate, and with the aid of which I propose to state the more important points in which the Albion measures differ from the rocks of similar age in their vicinity, and, if possible, to indicate the causes of these differences. 1. The coal of the Albion Mines is somewhat peculiar in its structure and chemical composition. It is more highly laminated, abounds more in mineral charcoal, is more bituminous and much more free from sulphuret of iron, than the coals of other parts of Nova Scotia. I t has also white and very light ashes, and has a remarkable power of continuing in a state of combustion when covered with ashes, and of remaining alight until all the coaly matter
