The extrusive rock unit includes basalt, andesite, boninite and albitite as well as breccia and tuff.

喷出岩单由玄武岩组成，还包括安山岩、玻安岩、钠长岩以及角砾岩、凝灰岩等。

There is an obvious rock zonation from the middle to bothsides of the structural shatter zone, generally from marialite orebody through diopside-felsite,biotite-albitite to the host Proterozoic rocks.

构造破带的岩具有明显的对称分带性：破带的中心钠柱矿体，向两侧依次透辉长英岩带、黑云母钠长岩带，并逐渐过渡围岩。钠柱矿的成因类型沿构造破带产出的热液交代脉型。
