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

原生岩为亮晶灰岩和泥晶灰岩，白化作用使其岩结构大破坏。

Grainstones are the main part of the section, among which the oolites, intraclast limestones and most bioclast limestones are cemented by sparry calcite.

颗灰岩在剖面中占绝大数，其中，灰岩、内碎屑灰岩和数生物碎屑灰岩均为亮晶方解胶结。
