Calculated the lower limit of abnormal after the plane through the delineation of the contour map of the occurrence and analysis of abnormal findings were as follows: work area on the lithology in terms of more or less divided into two parts, East and West, the western area for the low-resistivity, lithology is metamorphic carbonaceous sandstone or slate, for the emperor in eastern areas, lithology for granite and granite porphyry, quartz vein occurrence in eastern and more, these quartz veins is into the eastern part of the resistivity of the form of alternating high and low.

计算了异常下限值后，通过圈定了平面等值线图上的矿点异常和其它分析得到结论如下：工区就岩性而言大致划分为东西两部分，西部为低阻区，岩性为变质砂岩或炭质板岩，东部为高祖区，岩性为花岗岩及花岗斑岩，东部多赋存石英脉，这些石英脉是的东部电阻率成高低交替的形式。

The studies on mineralogy, fluid inclusions, and decrepitation temperature indicate that the gold deposit was formed by mixing of two kinds of fluids from different origins, instead of by gradual evolution of a single fluid.

石英脉型矿体主要与花岗岩浆热液关系密切，蚀变岩型矿体主要与深源流体有关，在矿体浅部它们强烈的挤压复合部位形成明金富矿体石英脉。

Through the geological work of Baxiannao area,we find that the area contains fracture zone compound type of quartz vein,the belt type of rock in thin vein,the belt type of greisen quartz in thin vein and some other kinds of the same stuff with multitype which are wolframite and cassiterite ore deposit polymetallic ore.

通过对八仙脑矿区的地质工作，发现本区存在破碎带-石英脉复合型、石英细脉带型、云英岩-石英细脉带型等一体多型钨锡多金属矿床类型，本文对其地质特征进行了较为详细的论述，总结了区内各钨锡多金属矿床类型找矿评价的工作方法。

Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。

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。

Fracturing of mineralization stage is found mainly concentrated in the early quartz veins or the hydrofracturing breccia in the sandy tectonic lenses, the lens-like orebody mainly consisting of the cataclastic quartz veins and hydrofracturing breccia form.

成矿阶段的破裂主要集中在砂岩构造透镜体中早期石英脉或液压角砾岩上，形成以碎裂石英脉及液压角砾岩为主要矿化母岩的透镜状矿体。

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。

It is considered that the quartz vein has something to do with concealed igneous rock., and its forming is because of pneumatolytic hydrothermal upwelling from magma differentiation in the deep.

综合分析认为，该区石英脉与推测隐伏火成岩体紧密相关，深部岩浆分异后期的气成热液上涌是石英脉形成的主导因素。

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.
