摘要

Abstract

A great quantity of cosmic dust (spherules) was found in deep-sea sediments during May to July

1983 manganese nodule investigations by theR/V “XIANG YANGHONG 16” in the area 7°–11° N

167°–178°W in the Pacific. Comprehensive study of the cosmic dust and determination with Laser Raman Molecular Microprobe (LRMM) of the molecules in it showed that besides Fe−Fe

Fe3+−O

Fe−Ni

Al−O

Fe−Obr−Si and S−Onb

it also contained the organic molecules C−H−O and C−H−S−O

various no fixed form molecules of C

CH2

CH3 and volatile molecules CO2

H2O

OH− and H2S

etc … The study result has very important applications for exploring the origin of interplanetary dust particles and life material.
