calcite dolomite 中文意思是什麼
calcite dolomite
解釋
灰質白雲巖-
Many carbonate masses older than middle palaeozoic are of dolomite rather than calcite.
中古生代以前的許多碳酸鹽類礦物是白雲石而不是方解石。 -
Most dolomite is obviously the result of replacement of precursor calcite but certainly not all.
多數白雲石顯然是原來方解石交代的結果，但肯定不是全部。 -
We find that the petrology characteristic of all the samples have no characteristic of meteoric water such as geopetal structure, infiltrative sand, ( uniform cement and gravitational cement on base of the research of the dolomite in the regions. on the dot diagram of combination of mgco3 ( mol % ) and sr, the dot are all close to the line of seawater whether they are microlite - crystalline penecontemporaneous dolostone or diagenetic dolostone of various crystals. the 87sr / 86sr value of dolostone or matrix is less than the one of sparry calcite in cave or vein, and close to the value of seawater
通過本區白雲巖的研究發現：已有的白雲巖樣品的巖石學特徵沒有顯示出如示底構造、滲濾沙、新月型膠結物和重力膠結物等大氣淡水作用的特徵；在白雲石mgco _ 3mol百分數和白雲石sr含量的投點圖中，無論是準同生成因的泥?微晶白雲巖，還是粉?細晶（或中晶，或細晶以上的不等晶）的成巖白雲巖，均投在海水線的附近；白雲巖（或基質）的~ （ 87 ） sr / ~ （ 86 ） sr比值顯著低於與孔洞或脈中充填的亮晶方解石，且與海水值十分接近， ~ （ 13 ） c和~ （ 18 ） o值顯著高於孔洞或脈中充填的亮晶方解石，也偏向于海水值； mn含量則顯著低於孔洞或脈中充填的亮晶方解石。 -
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。 -
The cement material consists mainly of calcite, clay, and minor amount of dolomite and pyrite
膠結物主要包括方解石和粘土，還有少量的白雲石與黃鐵礦。
