安徽亳县陨石研究

对亳县陨石进行了透明矿物、不透明矿物、球粒、穆斯堡尔谱、热释光、化学成分、同位素年龄、包裹体、力学性态的实验、古磁场特性等研究;确定了透明矿物16种;确定了不透明矿物12种,其中包括新矿物——张衡矿;确定了亳县陨石的化学群为LL,岩石类型为3—4之间的过渡型;对玻璃质球粒及球粒中玻璃质基质进行了研究与解释;对主要的球粒结构类型进行了成因上解释;对该陨石的形成与演化过程也进行了讨论。     

A STUDY ON BOXIAN METEORITE FROM ANHUI PROVINCE, CHINA

Investigation on the meteorite of Boxian, Anhui Province, China has been performed through transparent and opaque minerals, chondrules, Mssbauer spectra, thermoluminescence, chemical composition, isotopic chronology, inclusion, mechanical and paleomagnetic character, etc. The meteorite has 16 transparent and 12 opaque minerals, including a new mineral named Zhanghengite. The meteorite belongs to the chemical group of LL and the transitional rock type of 3—4. The principal textures of chondrules, the formation and evolution of the meteorite have also been studied and discussed.
