| Abstract: | The specimens of Lei-gong-mo (tektites) which form the object of the present study were collected from Hainan Island and Leizhow Peninsula during the period from 1963 to 1975.The distribution,forms,sculpture,abration surface (bald spot),internal structure and chemical composition of Lei-gong-mo are discussed and the studies of these materials lead to the following conclusions :1.The specimens of Lei-gotig-mo so far known can be morphologically divided into eight types.2.The sculptures on the surface of Lei-gong-mo are formed probably due to the corrosion effect of volcanic gas on it,and the abration surface due to the aerodynamic corrosion.3.The folded structures in the layered Lei-gong-mo (Muong Nong-type tektite) seem hardly to be formed by an impact of meteorites,but they might be produced in the flow process of magma when the Lei-gong-mo was melting within the crater vent.4.The comparison of its chemical composition with that of basalt from Hainan Island does not show that Lei-gong-mo came from the local volcano.Based on the studies mentioned above,the author is inclined to agree with the hypothesis of the lunar volcanic origin of tektites. |
