摘要
本文阐述了670地区角砾岩产状、形态、结构、组分诸方面特征,指出该地质体是在火山残浆及流体参与下,通过熔浆侵入、隐爆作用形成的产物;并在讨论该角砾岩成因的基础上,探讨了它在铀成矿作用中的意义。
Based on the characteristics of occurrence, form, texture and compositions of breccias in Area No. 670, this paper points out that the studied geological body was the product formed through magmatic intrusion and cryptoexplosion with the participation of volcanic residual magma and hydrothermal fluid; it also inquires into its significance in the course of uranium metallogenesis in terms of the origin of breccias discussed.
