宇宙尘的研究与月岩和陨石的研究一样,能够为探索地球起源和天体演化提供有用的数据。因此,多年来一直引起世界各国学者的关注。叶连俊等曾报道过我国燕山地区兴城附近震旦系地层中所发现的十亿年以前的宇宙尘。但是,由于当时受分析技术条件的限制,还缺乏充足的成分数据。近年来,随着电子显微分析技术的应用,国内外已有了较为详细的有关报道。最近在太平洋西部海域及我国南海和胶州湾海域沉积物中也找到了几种宇宙尘。本文系其研究的初步结果。
As with moon rock and meteorite research, the study of cosmic dust can provide useful data for exploring the origin of the earth and the evolution of celestial bodies. Therefore, it has attracted the attention of scholars all over the world for many years. Ye Lianjun et al. Reported the cosmic dust billions of years ago found in the Sinian strata near Xingcheng in Yanshan, China. However, due to the technical conditions at the time of the restrictions, but also the lack of sufficient composition data. In recent years, with the application of electron microscopic analysis technology, there have been more detailed reports at home and abroad. Recently, several types of cosmic dust were also found in the sediments of the western Pacific Ocean and the sea of South China Sea and Jiaozhou Bay in our country. This article is the preliminary result of its research.
