The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm，与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比，具有向短波长方向移动的特点，据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩；长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征，而基性超基性岩石显示Fe2+和Fe、MgOH特征，利用不同的铁价态和次要矿物可以区分它们：ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度；砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物，在221 μm（band 6）存在有特征的吸收谱带，并且在165 μm（band 4）具有较高的反射率，而蓝片/绿片岩在221 μm（band 6）反射率较高，不具有明显特征吸收谱带，同时其在165 μm（band 4）反射率较低，因此蓝片/绿片岩ASTER band4/band6 比值低。

The Changxing Formation reservoirs are mainly a set of reef dolomite, sparry oolitic dolomite, and have moderate to high porosity, moderate to high permeability and good physical properties. The reservoir space types are mainly intercrystalline pore, intercrystalline solution pore, intergranular dissolved pore, intragranular dissolved pore, moldic pore and dissolved expanding pore, and to a lesser extent, crack and suture.

长兴组储层主要为一套礁白云岩、亮晶鲕粒云岩和残余颗粒云岩，以高中孔、中高渗，孔隙型储层为主，储集空间类型以晶间孔、晶间溶孔、粒间溶孔、粒内溶孔、铸模孔以及溶蚀扩大孔为主，裂缝和压溶缝合线次之，具有较好的物性特征。

Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.

结果 二叠纪裂谷盆地的成岩强度大，以机械压实作用为主，原生孔隙丧失多且早，晚期成岩作用较重要，裂缝是油气运聚的通道和空间，可出现次生孔隙发育带；三叠纪－古近纪拗陷盆地的成岩作用表现为机械压实和化学压实作用并重，原生孔隙多被保留；晚海西、印支、燕山运动等表生成岩阶段对该区的成岩演化和油气运聚起到重要作用；二叠系中特征的泥云岩和藻云岩可能是在有淡水注入的较高盐度湖泊中经混合作用而形成的。

The crystal powder dolomite reservoir of Layer Jia22 B and micrite-crystal powder dolomite reservoir of Sub-member Jia21 are the principal fluid producing formation in Moxi Structure of the Central Sichuan Basin and have the favorable physical property and stable distribution in plane.

摘要嘉二2B层的粉晶云岩储层和嘉二1亚段的泥晶—泥粉晶云岩储层是川中磨溪构造嘉二段气藏的主力产层，物性较好，且平面上分布稳定，但测试成果显示，其产能相差甚远。

Dolomite in powders and rocks reacted with alkalies come from alkaline solutions or released by the hydration of cement to form brucite, calcite and CO〓ions. In concrete or cement compacts, CO〓ions produced would react with portlandite to form calcite and regenerate OH〓ions, which permited a continuing reaction with the dolomite.

在混凝土或水泥压实体中，反应生成的CO〓离子会与水泥中水化生成的羟钙石反应生成方解石，并再生OH〓离子，这有助于去白云化反应的继续进行。

The three types of dolomite have similar strontium content with higher ~(87)Sr/~(86)Sr ratios to some extent than that of the coeval seawater.The difterenee of distribution coefficient of Sr in calciteand dolomite is the most important control factor on the strontium content in dolomites.

三种类型白云岩具有类似的锶含量，但其(87)~Sr/(86)~Sr 比值均不同程度地高于同期海水值，锶在白云石和方解石中分配系数的差别是影响白云石化过程中白云石锶含量最为重要的因素。
