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
通過本區白雲巖的研究發現：已有的白雲巖樣品的巖石學特徵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徵；在白雲石mgco _ 3mol百分數和白雲石sr含量的投點圖中，無論是準同生成因的泥?微晶白雲巖，還是粉?細晶（或中晶，或細晶以上的不等晶）的成巖白雲巖，均投在海水線的附近；白雲巖（或基質）的~ （ 87 ） sr / ~ （ 86 ） sr比值顯著低於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值顯著高於孔洞或脈中充填的亮晶方解石，也偏向于海水值； mn含量則顯著低於孔洞或脈中充填的亮晶方解石。 -
Among of them, carbonate rock is the primary type of them, it is the product of stable platform facies of marine. we study the geochemical characteristic of carbonate rock of lower palaeozoic burial hills in the regions of zhuangxi and chengdao and find that the calcite fillings in cave or vein have high value of 87sr / 86sr, low value of 13c and 18o and high mn content among of different structural components. so it has been exposed to be dissolved by meteoric water on supcrgene diagenetic stage
通過對樁西、埕島地區下古生界碳酸鹽巖的地球化學特徵研究，表明在巖石的各種結構組分中，洞或脈中的方解石充填物具有顯著較高的~ （ 87 ） sr ~ （ 86 ） sr比值，較低的~ （ 13 ） c 、 ~ （ 18 ） o和較高的mn含量，其所經歷的重要巖溶作用是大氣淡水成巖作用，發生的時間為表生成巖階段。 -
The diagenetic environment results in different water - rock reaction and development of secondary porosity
成巖環境在一定程度上影響了水巖反應及次生孔隙發育。 -
Algae - rich carbonate of cambrian is typical sediment of foreslope facies in sandu and danzhai, eastern guizhou province. after sediment, it experiences many changes of diagenetic environment, and takes place much diagenetic altercation, among which the biggest is salt water dolomilization, and then is compaction, recrystallization, pressure solution, organic dissolution, burial dolomilization, cementation and silicification
貴州省東部三都丹寨地區中上寒武統富藻碳酸鹽巖是典型的斜坡沉積，其在沉積后漫長的地質歷史時期內，經受了諸多成巖環境的改造，發生了極大的成巖變化，最大的成巖變化為鹹水雲化，其他的成巖作用有壓實作用重結晶作用壓溶作用有機溶解作用埋藏雲化作用膠結作用及硅化作用等。 -
In the upper jurassic to tertiary, there is the alkali diagenetic ambient, in which the inter - pore fluid is inherited from the buried syngenetic water, i. e., alkali saline
上侏羅紀至第三系為堿性成巖環境，隙間流體繼承了封存同生水特徵，為堿性鹽鹵水。 -
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，我們認為樁西、埕島地區寒武?奧陶系白雲巖主要有兩種不同的成因類型，即準同生白雲巖和成巖白雲巖，並且成巖白雲巖是在埋藏成巖過程中，在粒間孔隙水中由交代作用形成的。
