Penecontemporaneous or seepage-reflux dolomitization is the original mechanism for gypsum-bearing muddy dolomicrite.

准生白云化或卤水回流渗透白云化是泥-微白云岩（含膏云岩）的形成机制。

The primary rocks were sparry oolitic limestone and micrite oolitic limestone, but dolomitization destroyed the original sedimentary textures.

原生岩为亮鲕岩和泥鲕岩，白云化作用使其岩结构大多遭受破坏。
