On TEM Method for Studying Ringwoodite with High-pressure Phase Minerals in Naturally Shocked Meteorites;

陨石中高压相矿物多形态林伍德石的电子显微研究

Chemical separation and purification of cosmogenic radionuclides ~(10)Be and ~(26)Al in meteorites;

陨石中宇宙成因核素~(10)Be和~(26)Al的化学分离纯化

Petrography and mineral chemistry of 100 meteorites collected from the Grove Mountains,Antarctica,were studied and their chemical-petrographic types were assigned.

本文主要报道了南极格罗夫山新回收的100块陨石的岩石学和矿物化学特征。

On the basis of the distribution area, density as well as the diversity of the petrographic, mineralogic and chemical characteristics, we regard the Escarpment zone in the Grove Mountains as a new meteorites enrichment area.

中国南极考察队于 1 998～ 2 0 0 0年两次对东南极格罗夫山地区进行了陨石回收工作 ,共回收 32块陨石 ,根据 1 5、1 6次队回收的陨石的分布范围、密度和岩石化学类型的差异性 ,初步确定格罗夫山阵风悬崖一带是一个新的陨石富集区。

Thermoluminescence studies of meteorites suggest that the level of natural TL in meteorites is determined by competition between build up,due to exposure to cosmic radiation,and thermal decay.

陨石热释光研究揭示了陨石中自然ＴＬ值取决于陨石暴露在宇宙空间时的宇宙射线辐照和自身热衰变之间的平衡。
