In:
Geological magazine : Vol. 92 Iss. 1-6 Year. 1955Summary: Abstract
Recent work in the Middle Shire Valley has revealed a swarm of biotitite bodies emplaced in gneisses and granulites of the Basement Complex. The rocks of the Basement Complex are described briefly and referred to the Amphibolite and Granulite Facies of regional rnetarnorphism. The field relations, distribution, and petrology of biotitite bodies show that they are a series of metamorphosed ultrabasic intrusions. An occurrence is described in which hydrothermal agencies have altered biotitite to vermiculite rock.
