摘要
A great quartity of cosmic dust（spherules） was found in deep-sea sediments during May to July,1983manganese nodule investigations by the R/V“XIANGYANGHONG 16”in the area 7°-11°N,167°-178°Win the Pacific.Comprehensive study of the cosmic dust and determination with Laser Raman MolecularMicroprobe（LRMM） of the molecules in it showed that besides Fe-Fe,Fe<sup>3+</sup>-O,Fe-Ni,Al-O,Fe-Obr-Si and Si-Onb,it also contained the organic molecules C-H-O and C-H-S-O,various no fixed form molecules of C,CH<sub>2</sub>,CH<sub>3</sub> and volatile molecules CO<sub>2</sub>,H<sub>2</sub>O,OH<sup>-</sup> and H<sub>2</sub>S,etc…The study result has very important applications for exploring the origin of interplanetary dust parti-cles and life material.
A great quantity of cosmic dust (spherules) was found in deep-sea sediments during May to July, 1983 manganese nodule investigations by the R/V 'XIANGYANGHONG 16'in the area 7°-ll°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 Si-Onb, it also contained the organic molecules C-H-O and C-H-S-O, various no fixed form molecules of C, CH_2, CH3 and volatile molecules CO2, H_2O, OH^- and H_2S, etc….The study result has very important applications for exploring the origin of interplanetary dust parti-cles and life material.
