矿体

Previously, the metallogenic epoch of the deposit was indirectly deduced by the ages of such nearby granitic rocks as granite porphyry and quartz porphyry or altered minerals.

其成矿时代以往都是用矿体附近的花岗质岩石或蚀变矿物年龄来间接推断的。

Combined with related rare earth element and trace element geochemistry of Huangshaping granites and ore-bearing skarn, it is concluded in this paper that the age of 154 Ma should represent the metallogenic epoch of the deposit, and that there existed a close relationship between the ore-forming process of the deposit and the granite porphyry, which were both formed during the peak stage of Early Yanshanian large-scale rock-forming and ore-forming activities in South China.

结合黄沙坪岩体及含矿硅卡岩型矿体的稀土及微量元素地球化学特征，得出以下认识：该矿床的成矿年龄在154Ma左右；成矿作用与花岗斑岩关系密切，它们都是华南燕山早期大规模成岩成矿作用高峰期的产物。

The Songshugou copper deposit occurs at the contact of a Permian porphyry granite and is clearly controlled by the porphyry granite.

松树沟铜矿矿体主要赋存于二叠纪花岗斑岩体外接触带，明显受花岗斑岩体控制。

Mine is too ancient geological ore mixed granite and granite porphyry, ores major components of SiO2, accounting for 76.54%, Al2O312.56%, Qianhui, the fine-grained gray granite block change crystal structure, long-ramp of 27 -- 36 percent, longer-35-42 percent, 20-29 percent quartz, rock weighing 2.6 T/m3, hardness of 5.9-6.3 degrees, the porosity of 0.62-1.03 percent, compressive 1670-1931 kg/cm2, bending 141-167 kg / cm2, ore reserves 2000 investigation Grade D geological reserves 10.02 million cubic meters, designed for the use of reserves of 7.99 million cubic meters; mining area of 0.4 cubic kilometres, the highest elevation of 151 meters, the minimum 56 meters, hilly slope, with perennial Shuixi, More sparse vegetation.

矿山地质矿体属太古代混合花岗岩及花岗斑岩，矿石主要成分SiO2，占76.54%，Al2O312.56%，浅灰，灰白色的细粒花岗变晶块状构造，斜长石含量27-36%，更长石35-42%，石英20-29%，岩石体重2.6T/m3，硬度5.9-6.3度，孔隙度0.62-1.03%，抗压1670-1931kg/cm2，抗折141-167kg/cm2，矿石储量2000勘测D级地质储量1002万立方米，设计利用储量为799万立方米；矿区面积0.4立方千米，最高海拔为151米，最低56米，丘陵缓坡，无常年水溪，植被较稀疏。

In Late Jurassic period (159-135Ma), when the orientation of maximum principal compressive stress was NW direction, the Wuzhangshan granite intruded to upward, accompanied the formation of NW trending Sanrenchang and Huangshuian breccia pipe belts; In the Early Cretaceous period (135-120Ma), when the orientation of maximum principal compressive stress was NNW trending, the second stage of Huashan granite intruded to upward, accompanied the formation of NW trending Qiyugou breccia pipe belts; In 120-105 Ma, when the orientation of maximum principal compressive stress changed to NE direction, the gold-bearing quartz veins and gold orebodies in breccia pipes were formed along the NE trending fractures; In the Middle Cretaceous period (105-85 Ma), when the orientation of maximum principal compressive stress was NEE, the NEE trending Leimengou granite porphyry intruded to upward, accompanied the formation of NEE trending Leimengou breccia pipe belts.

在晚侏罗世(159～135Ma)，构造应力场最大压应力方向为NW向，形成了NW走向的五丈山岩体以及NW向展布三人场、黄水庵两个角砾岩带；在白垩纪早期(135～120Ma)，最大压应力为NNW向，形成了花山岩体第二期上侵，并伴有NW向的祁雨沟角砾岩带；其后(120～100Ma)，构造应力场最大压应力方向变为NE向，形成了NE向含金石英脉及角砾岩体中金矿体；最后(100～80Ma)，形成了雷门沟花岗斑岩以及NEE向展布的雷门沟-杨河沟角砾岩带(区域构造应力场的最大主压应力方向为NEE向)。

The orebody is located in a contacting belt between granodiorite of Mesozonic and calcareous-aluminous rocks of Peleozoic,and controled by structure and nature of the rocks.

矿床产于中生代花岗闪长岩和古生代钙铝质岩石的接触带中，矿体受构造和岩性控制。

By studying the occurance of gold orebodies,the ore types and features and the alteration of wall rocks ,it is found that Xuyaogou gold deposit is a quartz vein-metasomatite type locating in the exocontact zone of Muhuding granodiorite.

通过对许窑沟金矿床矿体产出特征、矿石类型及特征、金的赋存状态以及围岩蚀变等的研究表明，许窑沟金矿是赋存于牧虎顶岩体外接触带的石英脉-蚀变岩型金矿床。

Our investigation shows that neither the dioritic porphyry nor the sedimentary rock is the source of iron ores, and that the source of most ironrich orebodies is the ore magmahydrothermal system in the deep chamber. Ore magma which was formed by liquid immiscibility is the main source of Gushan deposit, and the residual ironrich hydrothermal fluids which occurred as NaFeCl complex is the main source of Baixiangshan deposit.

根据野外观察和地球化学研究，文中认为，闪长玢岩岩体和沉积围岩均不是铁质的主要来源，富铁矿体的成因主要来自矿田深部的矿浆热液系统，姑山式铁矿的铁质主要是液态不混溶作用形成的铁矿浆，白象山式铁矿的铁质主要来源于深部残浆分离出的NaFeCl络合物。
