sparry iron

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 通過本區白云巖的研究發現:已有的白云巖樣品的巖石學特征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征;在白云石mgco _ 3mol百分數和白云石sr含量的投點圖中,無論是準同生成因的泥?微晶白云巖,還是粉?細晶(或中晶,或細晶以上的不等晶)的成巖白云巖,均投在海水線的附近;白云巖(或基質)的~ ( 87 ) sr / ~ ( 86 ) sr比值顯著低于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值顯著高于孔洞或脈中充填的亮晶方解石,也偏向于海水值; mn含量則顯著低于孔洞或脈中充填的亮晶方解石。

The primary rocks were sparry oolitic limestone and micrite oolitic limestone , but dolomitization destroyed the original sedimentary textures 原生巖石為亮晶鮞粒石灰巖和泥晶鮞粒石灰巖,白云石化作用使其巖石結構大多遭受破壞。
