1.Results indicated that the sulfur absorption rate is 10%15% for mid and early Cambrian dolomite; 15%26% for mid and early Cambrian dolomite; 30%47% for lower part of late Cambrian dolomite;
研究表明：中、下寒武系白云岩固硫率为10％～15％，石灰岩的固硫率为15％～26％，上寒武统下部白云岩的固硫率为30％～47％。
2.The later two stytes of mixing process are of a little difference from the traditional one. The angular gravel of breccia dolomite which has the same origin as the massive dolomite, replaced by Iow temperature hydrothermal, has a higher trace element value of Fe~(2+), Mn~(2+), Sr~(2+), Ba~(2+).
角砾白云岩中的白云岩角砾与下伏白云岩成因相同,但受后期低温热液的交代,使角砾白云岩的Fe~(2+)、Mn~(2+)、Sr~(2+)、Ba~(2+)显较高值,且有序度降低,最强衍射峰面网间距d_(104)值增大。
3.The results showed that white lime power, calcium carbonate power and dolomite power all worked well on improving brown red acidity and increasing cole yield, and the feasible applied amounts of modifiers should be 1125 ~ 1687.5 kg/hm2 of white lime power, 1500 ~ 2250 kg/hm2 of calcium carbonate power and 1500 ~ 3000 kg/hm2 of dolomite powder.
适宜的改良剂施用量为:熟石灰粉1125~1687.5kg/hm2、碳酸钙粉1500~2250kg/hm2,白云石粉1500~3000kg/hm2。
4.The wear reason of dolomite brick for AOD furnace is analyzed and the improving measure is put forward by analyzing the chemical composition and microstructure of the residual dolomite brick after used in AOD furnace.
通过AOD炉用白云石残砖的化学分析和显微结构研究 ,分析了AOD炉用白云石砖衬炉龄不高的原因 ,并提出了改进措施。
5.Combined with such as the seismic, well-logging data, core, FMI imaging logging data, the paper evaluates the reservoir of Ordovician in Ka 1 block, and designates tow type reservoir rock: dolomite, limestone and four type reservoir:dissolution-void reservoir, dispersive fracture reservoir, fracture-void reservoir, vertical fracture reservoir. Thereinto, dolomite of middle-lower Ordovician reveals be mostly fracture reservoir, limestone of upper Ordovician reveals be mostly dissolution reservoir.
卡1区块的主要储集岩为石灰岩与白云岩,储层主要有四种类型:溶蚀-孔洞型储层、分散溶洞型储层、裂缝—孔洞型储层、高角度裂缝型储层,中下奥陶统白云岩主要为溶蚀型储层,而上奥陶统石灰岩则主要发育裂缝型储层。
6.Based on the system coring and core analyzing materials combining log interpretation technology, the burial hill reservoir rock are mainly the dolomite of Ptd2 and the quartzite of Ptg4, meanwhile the quartzite of Ptg4 and the dolomite of Ptg2, g6 can also be the good reservoir rock.
利用本区潜山系统取心等岩心及岩心化验分析资料统计分析与测井解释技术相结合,确定潜山储集岩主要为Ptd2的白云岩及Ptg4的石英岩,其次Ptg4的石英岩、Ptg2、g6的白云岩也可成为有利的储集岩;
7.However, the authors discovered recently that the top and bottom surfaces of the Loushanguan Formation are palaeokarst unconformity interfaces, and there are a lot of interbeds of granular (oolite, pisolite and oncolite) dolomite and algae-mat dolomite, especially sedimentary structures such as the bird?s eye, stromatolite, cross bedding and tepee structures.
但笔者新近研究发现，其顶、底均为古岩溶不整合面，并有大量颗粒(鲕、豆、核形石)白云岩和藻纹层白云岩夹层，还有许多鸟眼构造、叠层石构造、交错层理、帐蓬构造存在。
8.2)the Lower Cambrian massive dolomite with relatively concentric values of δ 18 O and δ 13 C was the product of high density brine replaced dolomitizatin,whereas the lower Ordovician massive dolomite with high negative δ 18 O value was formed by the deep burial dolomitization;
（2）下寒武统厚层状白云岩具有δ18O和δ13C值相对集中，且δ18O略偏负的特点，而下奥陶统层状白云岩的δ18O具有很高的负值，反映了二者分别是高盐度卤水流交代白云岩化和埋藏白云岩化的产物；
9.The change in the microstructure and composition of the reactive carbonate rocks before and afterreacting with alkali was studied using AEM/EDS and thin film analytic techniques。 The distribution of Ca/Mgof dolomite in alkali-dolomite reaction was established.
应用分析电镜／能谱仪（AEM／EDS）和薄膜试样分析技术，研究了与碱反应前后活性碳酸盐岩的结构和组成变化，采用EDS定量分析测定了白云石晶体中的Ca／Mg（C）的分布，从理论上求出了碱－白云石反应碱溶液的pH临界值与白云石的组成C有关。
10.This geobarometer is more satisfactory than theprevious calcite-dolomite geobarometer. The typomorphic feature of the calc-ite-dolomite pair from the fault zone in this area is X_(Fe)~(Cc)>X_(Fe)~(Dol).
本文着重就该地区Fe~(2+)在方解石-白云石中的X_(Fe)~(Co)>X_(Fe)~(Dol)分配情况,提出新的计压方法。
