The dolomitized patches were produced by early diagenetic dolomitization which preferentially began within Thalassinoides burrows and spread into the surrounding lime mud.
云斑状构造是早期白云石交代作用优先沿着痕迹化石Ｔｈａｌａｓｉｎｏｉｄｅｓ潜穴进行，然后向围岩扩散而形成的。
Spotted structures are developed in ore-body and wall rock in Limin Gold Ore Belt .
斑点状构造是礼民金矿带矿化体岩石及围岩的显著特点,围绕中川岩体的北部、东部和南部成环带状于接触变质圈泥质岩石内发育,由岩体向外划分的红柱石亚带(Ⅲ)、(?)青石亚带(Ⅲ)、黑云母带(Ⅱ)和绿尼绢云母带(Ⅰ)中,其斑点构造的矿物组分由(?)青石+绢云母→黑云母+石英+黄铁矿。
