碎屑岩,尤其是角砾岩,除同生沉积和火山喷发成因者外,以往,几乎无例外地都视为构造作用的产物.构造角砾岩比比皆是,这种状况一定程度上妨碍了人们正确地认识碎屑岩类.近年来,随着岩浆地下“隐蔽爆发作用”及“爆发角砾岩”概念的引入和广泛研究,碎屑岩成因的构造一统说的传统观念动摇了,跃然而起的是一套别具特色的隐爆岩类.这种研究无论在岩浆起源、岩浆作用机制等岩理学的理论探索方面,还是在指导找矿方面,都有重要的意义.但是,随之而来的另一倾向是不加分析地把一些与岩浆隐蔽无关的角砾岩也都定为爆破角砾岩,甚至见之于公开发表的文章.这是有待澄清的.本文是在《江
Clastic rocks, especially breccias, have almost always been regarded as tectonic products except for genesis of synsegene and volcanic eruption, and tectonogenetic breccias abound to a certain extent, which hinders People have correctly recognized clastic rocks.In recent years, with the introduction and extensive study of the concept of “hidden explosion” and “breccia” in magma underground, the traditional conception of the unified formation of clastic rocks has been shaken, It is a distinctive set of implosion rocks which is of great significance.This research is of great significance not only in theoretical exploration of magmatic origin, magmatism mechanism, etc., but also in prospecting for ore deposits.However, It is to be clarified that the other tendencies that follow are that both breccia which has nothing to do with the magma occultation have also been identified as blasting breccias without any analysis. This is something to be clarified. "River
