Brief Description (Abstract):
Grain size analysis heavy mineral studies clay mineralogy and surface textural studies of quartz grains have been carried out on the offshore seabed sample from 215 m depth at 11?53 E - 69?57 S glacial sands and lake terrace sediments from the Schirmacher Oasis Queen Maud Land. Grain size of the sea bed sediments varies from coarse sand to clay size. Probability curve corresponds to marine shelf environment. Glacial sediment shows grain size variation from coarse sand to clay grade. Hornblende zircon garnet tourmaline kyanite epidote staurolite and hypersthene form the heavy mineral suite. llhte with subordinate chlorite are main clay minerals in lake terrace and offshore sediment .Plagioclase and phillipsite are also noted. Study of quartz grain surface textures by SEM show conchoidal fracture and V-shaped depressions. A probable glacial origin of the sands are inferred.
Status: Completed
Purpose: Present study deals with the sedimentological aspects of one offshore sea bed sample twelve land glacial sand samples and four samples from lake terraces of Schirmacher Oasis Queen Maud Land collected during the Third Antarctic Expedition. Most of the area is covered by thick ice Offshore sea bed sample was collected near the MV Finnpolaris wooring place. Glacial sands have been collected from the Schirmacher Oasis. Schirmacher Oasis has an area of 35 sq km.
