micrite
microcrystalline limestone
Examples
- The northern qiangtang basin suonahu formation microfacies of carbonate rock is divided for the intraclast ash lithofacies , biological detritus ash lithofacies , oncolite limestone lithofacies , contain the calcium and alga ash lithofacies , marl lithofacies and pure microlite limestone lithofacies
羌北盆地唢呐湖组碳酸盐岩微相为内碎屑灰岩相、生物碎屑灰岩相、核形石灰岩相、含膏藻灰岩相、泥灰岩相和纯微晶灰岩相等6种微相。 - This paper emphasizes the effect of the dissolution of aluminosilicate during diagenesis may provide more radiogenic strontium which would result in a high content of strontium in carbonate rocks . so we should avoid the vein of carbonate and select the samples with less terrigenous clastic , less grain content and lacking calcite cementation collected as analysis samples . the microcrystalline limestone and micro - to fine - crystalline dolomite are rather fairly whole rock samples
作者还强调了成岩过程中由长石等铝硅酸盐溶解提供壳源sr所造成的碳酸盐矿物成岩蚀变可能表现为较高的sr含量；因此，在用全岩样品进行旨在反映海水组成的各种分析时，应回避碳酸盐脉，选择含陆源碎屑低、颗粒数量少、缺乏方解石胶结物的样品，微晶灰岩或微?粉晶白云岩是较为理想的全岩样品。
