Overview

Excerpt from Journal of the Royal Geological Society of Dublin, Vol. 8 At the Meeting of the British Association of this year, held in Dub lin, I brought this subject, in conjunction with Mr. J ukes, before the Geological Section, and in a paper which I communicated at the Meet ing of 1843, held in Cork, I entered at some length on the discussion of the class of rocks to which the reddish-brown sandstone district, situate to the north-east of Lough Erne, should belong; and I then generally de scribed their unconformity with the red and gray sandstones which form the base of the Carboniferous series, and also their apparent conformity with the strata of the two small Silurian districts in the neighbourhood of Pomeroy and Lisbellaw. I also stated the probability of these brownish-red rocks being Silurian, from the analogy subsisting between them in the three districts I have mentioned, in two of which we find fossils of Silurian age. At the same Meeting, in a communication on the lower Carboniferous rocks, I pointed out that at Lisnarrick the Calp rests unconformably on the brownish-red conglomerates, while on the east and south the latter appeared to conform to the Silurian strata; and I observed that the red colour can no longer be considered a test of age, as it had been shown that red beds rested on undoubted Carboniferous rocks.
