Mineralogy of lacustrine sediments in the Schirmacher Range Area, Eastern Antarctica
A mineralogical study of the lacustrine sediment cores from lakes and varve deposits of the lake shore in the Schirmacher Range of East Antarctica is presented. Field observations and laboratory analysis indicate quartz and feldspar as principal allogenic phases derived from local crystalline rocks...
