Pyroxene from the Squilver dolerite, south Shropshire
Published online by Cambridge University Press: 14 March 2018
Extract
The andesine-dolerite of Squilver Hill, situated nearly 3 miles due north of Bishops Castle, has been described in another place. This somewhat coarse-textured rock, with a distinctive greenish-blue colour, contains up to 20 per cent. of a fresh monoclinic pyroxene as crystals of irregular shape, many of which are about a millimetre in length. The rest of the rock consists of saussuritized plagioclase, some interstitial chlorite and prehnite, and accessory apatite, sphene, magnetite, and ilmenite; the unaltered nature of the pyroxene is noteworthy.
