microcrystalline limestone 中文意思是什麼
-
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
作者還強調了成巖過程中由長石等鋁硅酸鹽溶解提供殼源sr所造成的碳酸鹽礦物成巖蝕變可能表現為較高的sr含量；因此，在用全巖樣品進行旨在反映海水組成的各種分析時，應迴避碳酸鹽脈，選擇含陸源碎屑低、顆粒數量少、缺乏方解石膠結物的樣品，微晶灰巖或微?粉晶白雲巖是較為理想的全巖樣品。
