Plant remnants replaced by bornite chalcopyrite and coveflive are described from Rongjing deposit, Sichuan Province, where at least chree stage have been depicted. Wood cell textures and textures reminiscent of wood leaves have thus been developed. Finally, an attempt was nade in order to clarify the organic matter related ore testures, in which both, sulghides and oxides can equally occur.

东北寨微细浸染一空代型金矿床赋存于三叠系碳酸盐岩-碎屑岩建造中，容矿岩石为含碳质黑色岩系。典型的矿石组构与含砷黄铁矿-雄黄-低温相毒砂-自然盘-辉锑矿-自然砷-石英-方解石为主的矿物组合显示低温浅成的矿石建造特征。同位素研究表明，矿质源于围岩系统，介质来自大气降水。包裹体测试结果说明成矿温度低（均-温度为236-129℃）、矿石就位浅（约1200-I600m）、流体盐度高（5.09-11.71，NaCI，wt），具一般地热卤水的特点。矿床成因属掺浣（滤）热卤水型。

从研究云南思茅-南坪盆地边缘造山带金（铜）成矿流体的地质地球化学特征和物理化学条件入手，通过氢-氧、碳-氧、氦-氩同位素组成示踪和矿物流体包裹体温度-压力、流体成分测试及物理化学参数计算，认为成矿溶液主要来自大气降水，并且成矿物质具有壳源的特点，不能排除构造/岩浆活动中其他壳源流体加入的可能性，其性状为浅成（低压）、低温、高盐度、弱碱性和弱还原性，流体组分别具有Na+>K+和Ca2++Mg2+、Cl->F-的特点，还原形式存在的硫占绝对优势，它对金的迁移和沉淀起着关键的作用；运用古水文地质学方法模拟成矿流体的水动力场与排泄条件，强调多成因含矿流体受古水文动力场运移、分布形式制约，高能量、高矿化度成矿流体经历漫长的地下反复溶滤、渗透、岩浆和构造驱动双重作用下，在水动力低压区排泄、沉淀富集成矿。

Laser Raman spectrochemical analysis on single inclusion reveals that multi-phase fluid inclusions exist in the Xuebaoding Beryl-Scheelite Vein Deposit. Besides the solid daughter mineral, there are vapor CO2, liquid CO2, water-deficient CO2 and salt water solution from its center to the border. A close study on the fluid inclusion components and carbon, oxygen, helium and argon isotope tracing and dating suggests that the volatile-rich ore fluid might derive from postmagmatic fluid and rare element enrichment is the result of the mixture of the plutonic alkali granite with crustal material.

The first independent Te deposit discovered in China occurs at northern pfunging end of Dashuigou thermal dome (diupiric granite) in centrel part of Daduhe ductile shear xine. The deposit is represented by an assembtage of Te, Bi, Sc, Au, Ag and Cu, in which Te is a muin mineraling element. The orebody occurs as vein form, oblique to Triassic metamiorphic rocks, Studies of mineralogy, fluid indusion and stuble isotope geochemistry suggers that Te has been concentrated during the early period of mineralization, and mineraliaztion fluid may be related to bydrothermal solution from granitic magma and meteocic water is conequent upon the fluid in the late period of Au mineralization. Preliminary study suggests that Dashuigou deposit represents a type of independent mesothermal Te deposit, which is mostly retated to granitic bydrothermal origin.
