摘要/Abstract

摘要：

After a field work on recently raised coastal features in South Shetland Islands, we conclude that there are three kinds of recent coastal features, i. e, fragmental coast, rock coast, and ice cliff coast. The processes and forms of the fragmental cost formed by wave action with floating ice are studied. Systermtic study of the raised coasts enables us to distinguish two groups of the coasts by an elevation of 20m a. s. l. The raised coasts above 20m a. s. l. belong to older group and those below 20m a. s. l. belong to younger group. Mean uplift rate of coast in this area is 6.7 mm/a.

Abstract:

After a field work on recently raised coastal features in South Shetland Islands, we conclude that there are three kinds of recent coastal features, i. e, fragmental coast, rock coast, and ice cliff coast. The processes and forms of the fragmental cost formed by wave action with floating ice are studied. Systematic study of the raised coasts enables us to distinguish two groups of the coasts by an elevation of 20m a. s. 1. The raised coasts above 20m a. s. 1. belong to older group and those below 20m a. s. 1. belong to younger group. Mean uplift rate of coast in this area is 6. 7 mm/a.

Key words: Coastal phenomena, isostatic uplift, Fildes Peninsula
