搞清古砂岩的物源是沉积岩石学的主要目的之一。随着对板块运动史的加深了解。人们对砂岩成份与区域构造的关系重新产生了兴趣。但这类研究大多限于物源区性质并非总能搞清,成岩作用杂沓的烙印使砂的源区特征变得模糊不清的古地层。本文是继论述现代深海砂的岩类学(译文见本刊1982年第2期所载的《现代深海砂的碎屑类型以及它们与构造背景的关系》和化学特征的文章之后的第三篇论
To clarify the provenance of ancient sandstone is one of the main purposes of sedimentary petrology. With the deepening understanding of the history of plate movement. There is renewed interest in the relationship between sandstone composition and regional tectonics. However, most of these studies are limited to the nature of the provenance area, and it is not always possible to find out the characteristics of the source area of the sand that have become obscure paleontology due to the imprint of diagenesis. This article is the third in a series of articles on the petrography of modern deep-sea sand (translated from “The Debris Types of Modern Deep-Sea Sand and Their Relationship to Tectonic Setting” and the Chemical Characteristics, 2nd ed., 1982) s
