Many dolomitization models have been invoked to interpret the origination of virious diagenetic dolomites. However, the genesis of earlyformed dolomites has long been an enigma in sedimentology, often referred to as the "Dolomite Problem".

All these evidences indicate that the dolomite is resulted from dolomitization due to mixture of sea water with fresh water from the penesyngenetic period to the early diagenetic stage in the environment of intertidalsubtidal zone of continental sea.

Major factors that have impact on the dolomite reservoir quality are originalsedimentary facies, dolomitization degree, dolomitization type, development degreeof tectonic fissure and property and intensity of deep burial corrosion.

Feixianguan Formation of lower Triassic is an important reservoir, which mainly consists of the dense oolitic dolomite and limestone altered by the late dolomitization of oolitic bars.

It is difficult to explain the origin of crystalline dolomite by traditional dolomitization mechanisms. The diagenesis of the Feixianguan carbonates should be governed by some kinds of marine fluids rich in strontium and poor in manganese.

The origin of dolomites is a research topic attracting great attention in sedimentology. Many dolomitization models have been invoked to interpret the origination of virious diagenetic dolomites. However, the genesis of earlyformed dolomites has long been an enigma in sedimentology, often referred to as the "Dolomite Problem".

However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.

但極低的錳含量黄色网站地址一、相對(duì)較高的鍶含量和包裹體均一化溫度等資料均不支持有94%的大氣淡水參與了結(jié)晶白云巖的白云石化作用，其白云石化流體應(yīng)是埋藏成巖過程中囚禁的近同期夜夜澡人模人人添人人看、但是非同期的海源流體国产乱弄免费视频观看，其來源可能與埋藏成巖過程中該時(shí)間段蒸發(fā)鹽的溶解有關(guān)。

TheJiyang depression located in paleomonsoon climate zone in the period of the sahejieformation sedimentation, the wet and hot climate made ancient lake become deeperwater, enhanced stratification, reduced primary productivity of plankton, decreasingsedimentary velocity of carbonate, increasing sedimentary velocity of clay, fortifiedreductibility on certain degree, and then would be available for development of blackshale, dark shale and oil shale; In the contrast, the cold and dry climate lead ancientlake to shallower water, subdued stratification, increaser primary productivity ofplankton, enhancive sedimentary velocity of aphanitic carbonate, decreasedsedimentary velocity of clay, and then would be available for development calciteshale, calcite laminar shale, calcite mudstone, shaly carbonate rock, even laminarcarbonate or dolomite rock.
