Jiapigou region is rich in gold and is one of the most important gold mining area in China. More than ten of gold deposits and over a hundred gold mineralizations were found along the Jiapigou-Dalazi compressional fault zone in the aureola 0-6 km to the south-west of Huangnihe Granite. In the same area huge quantities of veins were collected. Isotopic ages, the accessory minerals and petrochemistry of the veins are comparable to those of Huangnihe Granite.Trace elements and their abundances and K/Rb, Rb/Sr,...

Jiapigou region is rich in gold and is one of the most important gold mining area in China. More than ten of gold deposits and over a hundred gold mineralizations were found along the Jiapigou-Dalazi compressional fault zone in the aureola 0-6 km to the south-west of Huangnihe Granite. In the same area huge quantities of veins were collected. Isotopic ages, the accessory minerals and petrochemistry of the veins are comparable to those of Huangnihe Granite.Trace elements and their abundances and K/Rb, Rb/Sr, Mn/Ti, V/Ti, Co/Ni and Au/Ag ration are almost alike among the veins, the granite and the gold ore-bodies. In the K-Rb,Sr-Ba,Sm-La and(Sm/Fu)sample/(Sm/Eu)chondrite Sm diagrams, the projected points cluster in alike patterns; especially in the last knid of plot which shows the cognate relationship of rocks. The projected points are strictly in linear disposition. The shape, inclination and location of their chondrite-nomalized REE plots are nearly the same. All of their δEu values are positive and δCe values negative.The most important geological characteristics of gold deposits in Jiapigou region is that the gold ore-bodies and the veins coexist spatially and cut each other. According to their cross-cutting, the veins can be divided into three groups: (1)pre-mineralization veins; (2)syn-mineralization veins; and (3)post-mineraliza-tion veins The δD%. values are -86.72 and -86.06 to -91.3 respectively, nearly the same; the type, contents and Cu/Zn, Au/Ag and Co/Ni ratios of trace elements of quartz and magnetite in the granite are similar to those in gold ore-bodies; some ore-forming minerals,such as pyrite, galean, magnetite etc can be found in granite as accessory minerals.All evidences mentioned above undoubtedly indicate that the Huangnihe granite, the veins and the gold ore-bo'dies in Jiapigou region all are the products of a regenerated magma. Therefore the gold deposits in Jiapigou belong to Granite-magmatic hydrothermal deposits.

夹皮沟地区金矿床已有三十余年的研究历史,但关于金矿床的成因问题依然是众说纷纭。笔者利用大量的地质地球化学标志,论证了金矿脉与岩脉及岩脉与海西期花岗岩间的同源性,建立起夹皮沟地区海西期岩浆岩脉与金矿脉的形成演化序列。根据金矿脉与花岗岩之间明显的地球化学相似性,进而直接地证明了夹皮沟地区金矿床属花岗岩浆热液成因。

More and more attention has been paid to Northwestern Guangxi since micro- disseminated gold deposit was discovered in the middle Triassic turbidites there in 1985. On the basis of regional geological background and the geological characteristics of gold deposits, the authors place an emphasis on the analysis of gold mineralization such as resource material, water source, thermal source, ore -conducting and -hosting structures, physical - chemical conditions, transportation -deposition mechanism and ore -forming processes, and then come to a conclusion that the middle Triassic turbidite series is one of ore - hosted strata, but not source strata; and that the regional magmatism existed in the basement during mineralization. The authors point out that Ke's normal inspection method, porosity and permeability of sedimentary rock - masses,vitrinite reflectance and conodont colour change index are adopted to pick anomaly values in calculating abundance value of minerogenetic elements, and also discuss the relation between Youjiang turbidite basin and the mineralization, and the cause of zoning change of gold -hosted strata.

自1985年在桂西北中三叠统浊积岩中发现微细粒浸染型金矿以来,该区己受到世人所瞩目。本文在简介区域地质背景与矿床地质特征的基础上,侧重于金矿成矿作用分析。通过对成矿的三源(矿源、水源、热源)、构造(导矿、容矿)、物理—化学条件与运移—沉淀机制和成矿过程分析等,得出中三叠统浊积岩系为容矿岩系之一,而非矿源岩,成矿时基底存在区域岩浆热液活动的认识;并指出在求取元素丰度值过程中所剔除异常值性质的判断时,采用了柯氏正态检验法、岩石孔渗性、镜质组反射率与牙形石色变指数等研究方法的成果。还探讨了右江浊积岩盆地与成矿作用之间的关系、产金层位分带性变化原因。
