黄铁矿化的

The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.

矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S＝4.0‰—-4.2‰，呈塔式分布，δ〓S集中在0附近，表明其成矿体系具有均—化硫的同位素组成，而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰)，除一个样品外均为负值，这是硫同位素分馏作用的结果。

Based on the analysis of the occurrence characteristics of gold bearing pyrite veins in the area and its microscopic characteristics the paper explained the origin of mineralized veins using the principle of water pressure caused fracturing and further discussed the mechanism of holding and releasing super pressure fluid combined with the evolvement of the ore controlling structure recognizing the relation of idiomorphic coarse pyrite formed at the initial ore forming stage with gold enrichment .

在分析矿区内含金黄铁矿脉的产出特征以及镜下特征的基础上，应用水压致裂的原理来解释矿化细脉的成因，并结合控矿构造的演化，进一步阐述超高压流体的保持与释放机制，重新认识了成矿初期阶段中形成的自形粗粒黄铁矿与金富集之间的关系。

Their characters include (1) the particular configuration of the MT structures;(2) the obvious interface with rich organic matter and pyrite between the MT ribbon cracks and the host rock;(3) the host rocks are characterized by nonstromatolitic micrite limestones with few liminites;(4) the special macroscopic fossils of algae which were simultaneously developed with the MT structures.

这些特征包括：(1)臼齿状构造特别的形态学特征，(2)由微亮晶所充填的臼齿状裂缝具有明显的边界（以富集残余有机质和黄铁矿为特点），(3)臼齿状构造的宿主岩石是不发育叠层石和纹理化构造的隐晶质泥晶灰岩，(4)与臼齿状构造常常共生的极为特别的宏观藻类化石等。

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。
