Verdine and other associated authigenic (glaucony, phosphate) facies from the surficial sediments of the southwestern continental margin of India
Abstract
Green grains, pale green-brown infillings of foraminifer tests and brown friable aggregates occur in the coarse fraction of the surface sediments from the southwestern continental margin of India, between the Periyar River in the north and Quilon in the South. Study of the nature, distribution, mineralogy and internal structure of these particles resulted in (1) the discovery of a verdine facies and (2) determination of the relationships of phosphate with glaucony and verdine in these sediments
