Ankerite microclinite, a special type of rock, is closely related to the ore-forming process of massive sulfide deposits in the East Liaoning Proterozoic rift.

铁白云微斜岩作为一种特殊岩类型，在辽东元古宙裂谷块状硫物矿床中与成矿关。

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.

构造破碎带岩具有明显对称分带性：破碎带中心为钠柱矿体，向两侧依次为榍透辉英岩带、黑云母钠岩带，并逐渐过渡为围岩。钠柱矿成因类型为沿构造破碎带产出热液交代脉型。
