2. Notice on the Geology of Gottland, from the Observations of Mr Laing
Published online by Cambridge University Press: 16 March 2015
Extract
The fine Map of Sweden by Hissenger shews that the greatest part of that kingdom, to beyond the 61° N. Lat., may be characterized as a vast gneiss formation, skirted on the SW. and NE. by extensive detrital or alluvial formations.
The gneiss is interspersed with considerable tracts of granite, especially in the province of Ostergottland, and here and there exhibits small portions of hornblende-rock, porphyry, quartz-rock, mica-slate, and primary sandstone; but these rocks scarcely form any considerable tracts, and the scarcity of mica-slate is rather remarkable in a gneiss country.
