Petrologists,both at home and abroad have spent a lot of time on the classification of pyroclastic rocks, and suc_cessively put forward the classification of pyroclasts, the petrographic and the petrogenetic classification of pyroclasic rocks.
长期以来 ,火山碎屑岩的分类研究受到了国内外学者的重视 ,先后提出了火山碎屑物、火山碎屑岩岩性和火山碎屑岩成因分类。

meanwhile,the volcaniclastic rocks were modificated by the thermal fluid activity,for example,sericitization of plagioclase,chloritization of volc.
同时,受热流体活动的影响,热流体对火山碎屑岩具有一定改造作用,如在安山质岩屑凝灰岩中,斜长石绢云母化、火山岩岩屑绿泥石化明显;在凝灰质泥岩中,热流体对围岩中有机碳具有明显的"催熟"加热作用,微量元素则出现异常现象。
