成岩

Under the guide of the theories of advanced carbonate diagenesis and reservoir geology,and associating with the newest progress relevant domestic and abroad,systermatically researched the reservoir characteristics, property,pore texture,division and evaluation of upper Ordovician reef bank inTazhong62 well area both from macrography and micrography.

本文以当代先进的碳酸盐成岩作用、储层地质学理论和方法为指导，结合国内外相关的新近展，对塔中62井区上奥陶统陆棚边缘的礁滩体从宏观、微观的储层特征、性能、孔隙结构、分类、评价等方面进行了比较深入和系统的研究。

The result shows that there existed four type of anomalies, and this reflected the characteristics of element association under different geological conditions and an internal coordinating mechanism and spatial relation during the diagenetic and metallogenetic processes.

计算结果表明：该区存在4种异常类型，反映了不同地质条件下元素共生组合及其在成岩成矿过程中的内在组配机制和空间关系。

The diageneses include compaction, cementation, metasomatism and dissolution, etc.

成岩作用包括压实作用、胶结作用、交代作用、溶解作用等。

Agglomerated rock is a kind of binary microcrystal binding material which is synthesized artificially to geotectonic rock formation theory.

凝石是依据大地成岩理论人工合成的一种微晶二元胶凝材料，它由主体及配体2部分物料组成。

The SHRIMP age range from 16.35 Ma to 17.58 Ma, while the Re-Os molybdenite age is 16.85 Ma. The two groups of age sapan are very close.

这两组年龄在误差范围比较接近，成岩、成矿的时代都大约持续1Ma，前者略早于后者。

On the basis of the analysis to mineralizing system texture, the rock- and ore-forming ages of the granite-porphyry and related molybdenum ores were precisely redefined by the SHRIMP zircon U-Pb and molybdenite Re-Os dating method.

在对矿区矿化系统结构研究的基础上，应用锆石SHRIMP U-Pb法和辉钼矿Re-Os同位素测年法对成岩和成矿进行精确定年。

A Late Permian Changxingian coral reef was recently discovered in Cili, Hunan Province, South China.

笔者对近期在湖南慈利发现的长兴期珊瑚礁的白云石化作用及成岩环境进行了研究。

It is concluded that the age of ductile shearing is about 140 Ma, indicating that ductile shearing deformation occurs after petrogenesis and mineralization.

据此认为韧性剪切变形的年龄为140Ma左右，韧性变形发生在成岩和成矿之后。

It will be helpful for the understanding of a complete process of the petrogenesis and evolution of pegmatites, the impact of voltiles (including H〓O, F, B, P) on the physical prorerties of peraluminous magmatic system, and the fractionation of REE and incompatible elements in the system.

对上述问题的研究和探讨，将有助于了解伟晶岩形成和演化的全过程，有助于了解挥发分对过铝质岩浆体系物理性质以及对REE和其它微量元素地球化学行为影响，这对于理解过铝质岩浆体系成岩、成矿作用过程具有重大的理论和实际意义。

A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
