Solid hydrocarbon minerals occur in small quantities in the Lower Palaeozoic Welsh Basin, where Ordovician igneous intrusions mobilized them from local organic-rich source rocks. Hydrocarbon minerals are widespread in the Wenlockian and Carboniferous Limestones, and at least in the Carboniferous Lim

Abstract
A series of facies distribution maps with accompanying discussion is given for nine divisions of the Ludlovian; significant information on faunas and sedimentary features is incorporated. Isopachyte maps are presented for the whole of the Ludlovian and for its four component stages. Two sections are drawn across the area of sedimentation from northwest to southeast and northeast to southwest respectively. From the evidence assembled in these maps and sections deductions are made as to the probable palaeogeography of the Welsh Borderland area in Ludlovian times.

## Abstract The Nantglyn Flags consist of very thinly interbedded mudstones and laminated muddy siltstones with less frequent thin beds of calcareous siltstone. The lithology, sedimentary structures and fauna of these three rock types are described and discussed. It is concluded that the calcareous
Two formations are named in the presumed Precambrian sedimentary rocks of the Old Radnor Inlier. The Strinds Formation comprises fine-to medium-grained sandstones and pebbly sandstones. Grain-size, texture, clast types, and lithological invariance support correlation with the homogeneous and cross-b
