To the north and north-east of Cardiff there is a small inlier of Silurian rocks (described in detail by Professor Sollas in 1879) covering an area of rather more than two square miles. There are representatives of both the Ludlow and the Wenlock Series, and the general dip of the beds is towards the north, in which direction Ludlow mudstones pass with apparent conformity beneath the Old Red Sandstone.
