The metamorphic rocks consist of three basic-acid volcanic-sedimentary cycles and show the features of bimodal volcanic rocks.

东岩组地层由3个基性、酸性火山喷发 (溢)沉积旋回组成,具有双峰式火山岩特征。

The results showed that the metamorphic volcanic rocks were bimodal volcanic rocks,and its primary rocks were the alkali-basalt and the calc-alkaline rhyolite which both had the similar geochemical characteristics with those of t.

结果表明,矿区变质火山岩为一套以玄武岩为主的双峰式火山岩,其原岩为基性的玄武岩和酸性的流纹岩。

这些基性火山岩型和酸性火山岩型矿床被统称为昆仑式火山岩型块状硫化物铜矿床。

As the magma evolved chemically, it withdrew from the chamber underneath the summit, causing the ground there to collapse and feeding eruptions on the flanks.

随著岩浆的化学演进，从火山山峰下的岩浆库退去，造成地面塌陷，并促成了侧边的爆发。
