GEOLGY OF FILDES PENINSULA,KING GEORGE ISLAND,WEST ANTARCTICA——A Study on the Stratigraphy and Volcanism

On the basis of the geological mapping, isotopic choronoogcal and petrological evidences, the aumors suggested that the early Tertiary volcanic strata in the Fildes Peninsula could be divided into two formations and four members. The erupted centers in the peninsula were gradualy migrating from the western coast to the eastern and the subvolcanic intrusives were regularly distributed along a series of NWW-SEE trending faults. All of these were basically formed in two stages of volcanic activities from Paleocene to Eocene.
