In this investigation also Mr. Storrie gave valuable assistance. The Map is issued in two editions. On the edition for Solid Geology the Glacial Drift is omitted, while on the Drift edition the areas occupied by Drift are coloured, as well as those portions of solid geology which are not concealed by the Drift. Manuscript six-inch maps, geologically coloured, are deposited...

Page 32 - ... the calcareous rock assumes its usual highly fossiliferous character. That the little vent from which the discharges took place lay to the westward, under what is now the Bristol Channel, may be inferred from the disappearance of the volcanic zone as the ground is traversed in the opposite direction. Fragments of the amygdaloid were found by Mr. SPENCER PERCEVAL at the Tollgate, which show that this rock extends inland for a mile and a half. But immediately to the east over the bare limestone...

Page 31 - Weston-super-Mare [E. 3212 (23)], is a finegrained, chocolate-coloured rock, composed of pseuaomorphs after olivine, and probably augite, in a groundmass showing microlitic structure. The phenocrysts are represented by pseudomorphs in carbonate. The microlitic felspars of the groundmass are colourless, but they no longer show their characteristic optical properties. The groundmass is deeply stained with ferric oxide. Although all the minerals have been destroyed, the structure has been perfectly...
