摘要/Abstract

摘要：

A large number of cosmic dust particles, micrometeorites and volcanic dust bands have been found and collected in Antarctic ice, snow and glacial sediments, especially in meteorite concentrated regions. Extraterrestrial spherules also have been discovered from the stratosphere and deep-sea sediments. On the basis of their distributive characteristics the cosmic dust particles are classified into interplanetary dust particles and interstellar dust particles. According to their origins cosmic dust particles can be divided into cometary origin particles, asteroidal origin particles, ablation particles from meteorites and interstellar origin particles. The criteria for identifying cosmic dust particles have been established and the origins of cosmic dust particles are also discussed in aegis paper.
