中国矿物岩石地球化学学会陨石学与天体化学委员会和中国空间科学学会空间化学与空间地质学委员会于今年5月22—26日在长沙召开了《全国第三届陨石学、空间化学与地质学学术讨论会》。在会议上宣读了65篇论文,反映了我国陨石学、空间化学与地质学的研究工作领域扩大了,研究程度加深了,研究水平又有新的提高。对当前国际上共同关注的一些重大课题,在许多方面我国学者提出了新的理论与见解。 1.我国听收集到的地外物质的研究我国已收集有近百次陨石的样品。每年能获得 China Society for Geochemistry of Mineralogy of Petrology and Astrochemistry and the Chinese Society of Space Science Space Chemistry and Geospatial Geological Commission held in Changsha, May 22-26 this year, “the third meteorite, space chemistry and geology discussion”. 65 papers were read out at the conference, reflecting that the areas of research in meteorite science, space chemistry and geology have been expanded, the degree of research deepened, and the level of research increased again. On the major issues of common concern in the international arena, our scholars in many aspects have put forward new theories and opinions. 1. China to listen to the collection of extraterrestrial material research China has collected nearly 100 meteorites samples. Can be obtained every year
