Examples
- 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
通过本区白云岩的研究发现：已有的白云岩样品的岩石学特征没有显示出如示底构造、渗滤沙、新月型胶结物和重力胶结物等大气淡水作用的特征；在白云石mgco _ 3mol百分数和白云石sr含量的投点图中，无论是准同生成因的泥?微晶白云岩，还是粉?细晶(或中晶，或细晶以上的不等晶)的成岩白云岩，均投在海水线的附近；白云岩(或基质)的~ ( 87 ) sr / ~ ( 86 ) sr比值显著低于与孔洞或脉中充填的亮晶方解石，且与海水值十分接近， ~ ( 13 ) c和~ ( 18 ) o值显著高于孔洞或脉中充填的亮晶方解石，也偏向于海水值； mn含量则显著低于孔洞或脉中充填的亮晶方解石。
