CAINOZOIC AEOLIAN SEDIMENTS AND THEIR DIAGENESIS AT ISIPINGO BEACH, NATAL SOUTH COAST, SOUTH AFRICA

摘要

Calcareous arenites at Isipingo beach, Natal south coast, Republic of South Africa are aeolian sediments of Cainozoic age. The aeolianites show two patterns of cumulative frequency curve, with grain-size parameters of Mz=0.823 to 2.353<)>, So=0.434 to 1.048<|>, SK,=-0.2 65 to 0.2S2 and Kg=0.786 to 1.276, reflecting a varied dynamic aeolian environment. Two major types o? sedimentary facies, i.e. the large scale (>2m) high-angle (30-3
