diagenetic dolostone 中文意思是什麼
-
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。 -
The formation mechanism of the pore of diagenetic dolostone includes : 1 ) the primary porosity is essential condition for the formation of dolostone reservoir
成巖白雲巖孔隙的形成機制有: l ）巖石的原生孔隙度是成巖白雲巖儲層形成的必要條件。 -
The reservoir of dolomite is mainly distributed in diagenetic dolostone. so the formation mechanism of diagenetic dolostone have directly relation with that of the reservoir pore
白雲巖儲集巖主要分佈在成巖白雲巖中，因而成巖白雲巖的形成機制便直接與儲層孔隙的形成機制相關。 -
So we can draw a conclusion that the dolostone of c - o stratum in the regions of zhuangxi and chengdao has primarily two genesis types, they are penecontemporaneous dolostone and diagenetic dolostone. the diagenetic dolostone is formed by replacement in intergranular pore water on the course of burial diagenesis
因此，我們認為樁西、埕島地區寒武?奧陶系白雲巖主要有兩種不同的成因類型，即準同生白雲巖和成巖白雲巖，並且成巖白雲巖是在埋藏成巖過程中，在粒間孔隙水中由交代作用形成的。 -
A lot of diagenetic dolostones have remainder granulation structure, and the native rock of it may be various intraclast limestone. this type of rock usually has high primary porosity. the high primary porosity is the important base of forming the pore of dolostone reservoir
一部分成巖白雲巖仍具有殘余粒屑結構，其原巖可能主要為各種類型的粒屑灰巖，這類巖石通常具有較高的初始孔隙度（原生孔隙度） ，這是以後形成成巖白雲巖儲層孔隙的重要基礎條件。
