Summary The paper presents petrographical data and chemical analyses on the dioritic, tonalitic and granodioritic igneous rocks of the Midlands, which appear to be emplaced in argillaceous sediments of Lower Palaeozoic age. It is deduced that a subordinate Caledonian igneous-tectonic mountain belt lies buried, mostly beneath Trias and later rocks, along a WNW-ESE direction through the Midlands of England and that it may extend to the Brabant Massif of Belgium.
