假玄武玻璃及其形成过程和机制综述

对假玄武玻璃的概念和特征以及形成环境和产状作了综合性描述，并对其摩擦熔融成因进行了论证，对假玄武玻璃的形成过程和形成机制以及形成假玄武玻璃的地震断层的动力机制、活动方式和脉动性质进行了深入探讨；同时对母岩矿物性质和流体对假玄武玻璃形成的影响进行了分析，概述了假玄武玻璃形成过程中的化学成分变化，最后提出了有待进一步研究的几个问题。

A GENERAL SURVEY OF PSEUDOTACHYLYTE AND ITS FORMATION PROCESS AND MECHANISM

In this paper are summarized the concept, characteristics, occurrences and formation enviornments of pseudotachylyte, and its frictional-melting origin. A thorough discussion is also made on the process and mechanism for the formation of pseudotachylyte, the dynamic mechanism, behavior and pulsation of the seismic fault in which the pseudotachylyte was generated. The effects were analyzed of the minerals properties and the fluid in host rocks on the formation of pseudotachylyte. The chemical changes during the formation of pseudotachylyte are also dealt with in this paper. Finally, several problems for future investigation are put forward.
