Between east and west, the mineralization in subalkalic intrusive complex is different. In the west, the veins are chiefly quartz veins, quartz veinlets and network veins, the wall rocks are mainly syenite and quartz monzonite. In the east, the fine quartz network veins, altered kata-rocks, alkali-syenite and syenite are dominant.

成矿作用在偏碱性侵入杂岩体的东部与西部有所不同，西部多以石英脉、石英细脉、网脉型为主，围岩以正长岩、石英二长岩为主；东部则多为石英细网脉和破碎蚀变岩型，围岩主要是碱长正长岩、正长岩。

The study of the geological characteristics, ore-forming condition and genetic type from the Pingdingshan gold deposit, shows that the cryptomerous diorite and dioritic porphyrite in different stages formed a vein rock zone with gold containing ore bodies in the area, and five vein ore bodies were blocked out by spreading out with the NNE direction in the field.

黑龙江嘉荫平顶山岩金矿床的地质特征、形成条件和成因类型的研究表明：矿区内不同阶段的细晶闪长岩、闪长玢岩形成一个含金矿体的脉岩带；矿床范围内圈定5条呈脉状沿北北东向展布的矿体；矿石类型为石英脉型和蚀变岩型；金以裂隙金、晶隙金和明金为主，以银金矿的形式存在，且主要与石英、黄铁矿、毒砂和水云母共生；成矿作用分为热液期及表生期，其中热液期又分为4个成矿阶段，即纯石英阶段，黄铁矿毒砂石英阶段，黄铁矿毒砂水云母石英阶段和石英碳酸盐阶段。

According to modes of occurrence, auriferous quartz veins might be divided into three types:(1) bedding quartz veins;(2) ferriferous dolomite quartz veins;(3)quartz veins along NE trending joints.

根据含金石英脉的产状可将其分为三种类型：①顺层石英脉；②含铁白云石石英脉；③NE向节理石英脉。

The quartz in this region shows a array of deformations from High-temperature -High pressure condition to crust environments: coesite → the high-temperature quartz → sheared quartz vein → feldspathic shear zone (the quartz from two-mica schist)→ the ordinary quartz in eclogites.

7本区石英的变形构成了一个从高温高压到中上地壳的连续变形序列：柯石英→榴辉岩中高温石英→剪切石英脉→长英质剪切带(超高压二云母片岩中石英)→榴辉岩中普通静态重结晶石英。

Based on study of the thermoluminescent features of q uartz from vein No.505 and No.530 in Wenyu gold deposit,the value 10 000CPS for total thermoluminescent intensity and 150CPS for thermoluminescent peak strength of quartz were proposed as quantitative indicators to evaluate the auriferous f eature of quartz veins.According to this criteria,mapping of thermoluminescent intensity of quartz on limited parts of vein No.505 and vein No.530 were carried out,and conclusions that the deep parts beneath the e...

在对文峪金矿床505、530脉石英矿物热发光特征研究基础上，提出了以石英热发光总强度1000CPS，峰强150CPS为评价石英脉含金性的定量判别标志；根据上述准则，开展了505及530脉局部范围的石英热发光强度填图工作，并得出了505脉13中段及530脉10中段在现在矿体深部仍有较好成矿前景的结论，为脉型金矿床深部成矿远景评价提供了新的途径。

The rock gold deposits born in Pre-cambrian system stratum and performed as bed-bear ing quartz vein, shear-quartz vein, stringer vein. alteration host rocks and tectonic breccia etc. and embraced with many ascepts of common metallogenetic geology characteristics, not only have the obvious and close distributional relationship on tectonic zones, but also share possibly the same genetic mechanism.

研究表明，产于前寒武系地层中，以层间石英脉、剪切石英脉、石英细脉、蚀变围岩、构造角砾岩等多种型式产出的、具有很多共性成矿地质特征的岩金矿床，不仅具有明显密切的空间展布关系，而且更重要的是它们可能具有某种深刻的内在共性成因联系。

Beginning with areal geologic background, the authors have discussed the features of quartz vein at Rujigou mining area Ningxia, such as lithology, contact correlation with wall rock, scales, space-time distribution, attitudes, assemblage, mineral inclusion, and have compared the quartz vein with the veins within other coalfields and coal measures.
