碎屑岩

They mainly consist of sandstone,in which quartzarenite and litharenite are dominant and arkose is lack.

碎屑类为主，其中又石英类和屑类为主，缺少长石类。

The first rock is mainly andesite clinkering agglomerate, andesite breccia, dacite breccia, rhyolite breccia and rhyolite clinkering tuff.

正常火山碎屑亚类石类型主要为安山质熔结集块,安山质、英安质及流纹质火山角砾及流纹质熔结凝灰。

The ore-bearing beds have a bimodal rock association and exhibit assembly characteristics of pyroclastic rock, orebody and exhalite.

含矿系为双峰石组合，具有火山碎屑-矿体-喷气“三位一体”特徵。

Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.

在红色碎屑建造中有层间氧化带和“泥--泥”结构发育，并有良好水承压和循环体制，是寻找可浸型铀矿有利区。

Xiaertai rock group,a set of metamorphic rock system in Xiaertai area,has experienced strong ductilebrittle deformation and then thermal contact metamorphism and dynamometamorphism in the late stage.

经原恢复可将二台群分为三个组：盘岭组，黄顶子组及烧锅屯组，其原建造分别为火山建造、碳酸盐建造及碎屑建造。
