A study on the characteristics of regional geological setting, geologyof the deposit, isotopes of sulfur and lead, composition of fluid inclu-sions, and physico-chemical conditions of mineralization, all of theseindicate that the cassiterite-sulfide deposit in Beimianshan, Guangxi, isa post-magmatic hydrothermal deposit. This deposit had been formed byfilling and metasomatizing of the hydrothermal solution along the favour-able layers. The physico-chemical conditions of the mineralization are asfollows: the temperature from high to middle and low (355~103℃),pressure middle (800~1140 bar), slightly acid (pH=3.98~5.15), boththe fo_2 (10~(-32)~l0~(-94) atm) and fs_2(10~(-4)~10~(-12·5)atm) low. It seemsthat tin in hydrothermal solution had been transformed in the form offluorine-hydroxyl complex [Sn (F, OH)_x]~(4-x). The main factor had led todecempositing of the complex and precipitating of cassiterite as well asassociated metal sulfide was the reaction of hydrothermal solution withcarbonate rock, which had made the decrease of temperature and increaseof pH of the solution.

区域地质背景、矿床地质特征、硫铅同位素和包裹体成分特征以及成矿物理化学条件研究表明,白面山锡石硫化物矿床是岩浆期后热浪沿不同构造裂隙多次上升,在有利层位和构造条件下充填交代围岩形成的。成矿时的物理化学条件是高至中低温、中压、偏酸性和氧、硫逸度低。锡在热液中可能主要以Sn~(4=)的氟羟基络合物[Sn(F,OH)x]~(4-?)形式搬运;导致络合物分解、锡石和共生硫化物沉淀的主要原因是热液与碳酸盐类岩石起反应,温度降低,pH值升高。

The metallogenetic region of Shexingping lead-zinc deposit occures in the contact zone of granite and carbonatite. The former scholars considered it as a magmatic-hydrothermal deposit. Based on the synthetical study of the characteristics of the deposit, we regard it as a deposit which is formed under the synthetic control of the three ore-forming conditions: source beds metallogenetic body and structural position. So no matter whether in practice or in theroy, it is very significant to summarize the geological characteristics and ore-forming condition of this kind of deposits.

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。
