2The Cosmic Dust in Suzhou Granite:Ablated Products of a Cometary ExplosionHu Zhong-wei,Wang Er-kang,Wan Yu-qiuDepartement of Astronomy,Nanjing University,Nanjing 210093,China Department of Earth Sdence,Nanjing University,Nanjing 210093,China Cosmic dust has been collected in large number from deap-sea sediments,Greenland ice deposits,the stratosphere and space,of cosmic dust,some are the unmelted micrometeorite,and most are the ablated products of me-teoroids in the atmosphere.Cosmic dusts were recovered from two sites of the 1908 Tunguska explosion and the 1965 Revelstoks explosion Since 1987,a large number of microspherules have been extracted from Suzhou granite of China Their suface and section structures,mineral and chemical composition show that these microspherules are of the ablated cosmic dust.The microspherules occurred in the inner contact complex intrusion.It suggests that the microspherules may be products of the same event and were aggergated in some strata and then captured by the emplacement of granitic magma.Although the microspherules are similare to other ablated cosmic dusts,there are some diferences.Our calculated results of cometary motion through the atmosphere and explosion show that the microspherules may be the ablated dust of a comet with mass above 1015g at its explosion near the ground. 1996紫金山天文台台刊1996,15,3:2
