Overview

Excerpt from On the Geology of the Neighbourhood of Carmarthen The outcrop of this series serves as a datum-line throughout the district, owing to the fact that the fossils are characteristic and abundant. The beds sweep across the country in a straight line from Felin-wen on the east to beyond N ant-y-ci on the west. From this point westward the outcrop takes a southerly bend, owing to the closing in of the anticline, and exposures occur south of Melin Ricket as described by the late Mr. Roberts. The general dip of the beds is magnetic north, at a greater or lesser angle with that of the cleavage. No actual junction with the higher beds is seen except in Pistyll - y-gwion quarry, where a yellow sandy series overlies the shales. The sporadic appearance of this sandstone, and the fact that we have here the higher beds of the Didymograptus Murchisoni-zone, render it admissible to suppose that the sandy rock is a local development of Llandeilo Limestone, otherwise absent throughout the district. Just north of the Plough and Harrow Inn higher beds also occur. N o certain boundary-line can at present be drawn between these beds and the underlying btfidus shales, as fossils are so exceedingly rare in the upper part of the latter.
