摘要
宇宙尘较广泛地分布于各地质时代和各种岩石中,它形成在不同的物理化学环境下,因此具有比较复杂的结构构造。本文对产于不同时代、不同岩性岩石中具有似文象结构的宇宙尘进行了广泛的研究,一方面研究Si、Al等元素的赋存状态,另一方面研究这些元素与似文象结构的关系,进一步为它们的成因提供信息。
Cosmic dusts are widely distributed in various types of rocks of different geologic times. They were formed under different physico-chemical conditions, exhibiting complex textures and structures.This paper deals with cosmic dusts occurring in different types of rocks of different geologic times. Studies have been conducted on the existing forms of Si, Al ang other elements on one hand and on the relations between these elements and graphic texture on the other hand so as to ascertain the origin of the cosmic dusts.
