penecontemporaneous meaning in Chinese

沉积后到固结前的准同期的准同生的
准同时的

Examples

According to the mechanism of dolomitization , it can be divided into penecontemporaneous dolostone and post - penecontemporaneous dolostone
白云岩可据白云石化作用的机理和时间分为准同生白云岩和准同生后白云岩两大类。
According to whether remnant grains exist , post - penecontemporaneous dolostone can be divided into remnant grain dolostone and crystalline dolostone
准同生后白云岩根据残馀颗粒的有无可分为残馀颗粒白云岩和晶粒白云岩两大类。
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。
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，我们认为桩西、埕岛地区寒武?奥陶系白云岩主要有两种不同的成因类型，即准同生白云岩和成岩白云岩，并且成岩白云岩是在埋藏成岩过程中，在粒间孔隙水中由交代作用形成的。
