(Table 1) Chemical composition of palygorskite and host sediments from Core VITYAZ4599-GC

Palygorskite streak veinlets were studied in the lower part of a sediment core collected at Station VITYAZ4599 in the central (Mid-Indian) basin of the Indian Ocean. It is suggested that this palygorskite is of hydrothermal origin and was formed in pre-Pliocene time.

对印度洋中部（中印度洋）海盆VITYAZ4599站位采集的沉积岩心下部的坡缕石（Palygorskite）条带状细脉开展了研究。研究表明，该坡缕石属于热液成因，形成于上新世之前的地质时期。
