前寒武纪沉积岩石学和沉积地质学是现代地质学的一个主要组成部分之一,因为陆地的前寒武纪杂岩在地球开始的历史阶段中占主要位置,并且包括了绝大多数的金属和非金属矿产。 1973年4月16—19日在莫斯科召开了第十次全苏沉积岩会议。来自88个单位的700多人参加了会议。会议的主要讨论议题有:(1)沉积变质岩的岩石学、原生介质和研究方法;(2)前寒武纪风化作用和沉积作用的各种问题:(3)前寒武纪的活质和有机质及其
Precambrian sedimentary petrology and sedimentary geology are one of the major components of modern geology because the pre-Cambrian complex terrestrial predominate in the historical stage of the Earth’s beginning and include the vast majority of Metal and non-metallic minerals. The 10th Quanzong Sedimentary Rock Conference was held in Moscow from April 16-19, 1973. More than 700 people from 88 units attended the meeting. The main topics discussed at the conference are: (1) petrology, original media and research methods of sedimentary metamorphic rocks; (2) various problems of Precambrian weathering and sedimentation; (3) Precambrian And organic matter and its
