The formation of a tight syncline in the tuchengzi formation is depicted accurately . 3 . there are three main clast types in the conglomerate : andesite , limestone , and dolomite 4 、确定了土城子组砾岩中的三种主要砾石成分(安山岩、灰岩和白云岩砾石)的来源。
In the thesis , the ree concentration and ree distribution patterns are also studied for stream water , granite fissure water and water from carbonatite around the baisha region 本文还讨论了该区的河水、花岗岩裂隙水、灰岩出露地区地下水的稀土含量及其分布模式。
In the same conditions of temperature , pressure and specific surface area , the start - up dissolution velocity of limestone sample is more than the dolostone ' s one 在相同温压、相同比表面积的条件下，灰岩类岩石样品的启动溶蚀速率大于白云岩类岩石样品的启动溶蚀速率。
In the light of the engineering application , the applying basis , effects and prospects of the high - density resistivity method in the limestone area have been discussed in this paper 摘要从工程应用的角度出发，探讨了高密度电阻率法在灰岩地区的应用基础、实际效果和应用前景。
On the point favorable reservoir zones are predicted . it is suggested that donghe sandstone and bioclastic limestone members should be main targets of oil - gas exploration in the region 据此作出有利勘探区带预测，建议将东河砂岩段和生屑灰岩段作为本区油气勘探的重要目标。
The microfacies characteristic of carbonate rock of suonahu formation in cuoqinin basin constitutes with the marl lithofacies , the intraclast ash lithofacies , biological detritus ash lithofacies 措勤盆地唢呐湖组碳酸盐岩微相由内碎屑灰岩相、生物碎屑灰岩相和泥灰岩相组成。
The well - developed rimmed textures indicate that the dolostones in the study area resulted from the diagenetic replacement of limestones by mixed meteoric - marine pore fluids 广泛发育的白云石环边结构等淡水成因标志表明，该区白云岩是通过大气水海水孔隙混合流体交代灰岩所形成的。
Abstract : in the light of the engineering application , the applying basis , effects and prospects of the high - density resistivity method in the limestone area have been discussed in this paper 文摘:从工程应用的角度出发，探讨了高密度电阻率法在灰岩地区的应用基础、实际效果和应用前景。
Synthesizely contrasted the suonahu formation profile of the northern qiangtang basin and cuoqin basin of miocene epoch , used the intraclast ash rock as the marker bed of the suonahu formation 对羌北盆地和措勤盆地中新世的唢呐湖组剖面作了综合对比，将内碎屑灰岩作为唢呐湖组的标志层。
Wudaoliang group is grayish - white , yellow - grey , dark - grey ash rock , which interbeded with the conglomerate , sandstone , a little amount mudstone , oil shale with unconsolidated sand mud rock 五道梁群以灰白色、灰黄色灰岩为主，含有砾岩、砂岩，夹有少量泥岩、油页岩和未固结砂泥沉积。
