钠长岩

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

喷岩单元不仅仅由玄武岩组成，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.

构造破碎带岩石具有明显对称分带：破碎带中心为钠柱石矿体，向两侧依次为榍石透辉石长英岩带、黑云母钠长岩带，并逐渐过渡为围岩。钠柱石矿成因类型为沿构造破碎带热液交代脉型。
