After analysis of hydrocarbon to different kinds of ore, rock and inclusion, it is discovered that organic materials had been more or less participated in the mineralization process of Au, Ag, Sn, Pb, Zn, Cu, Sb deposits (include some mid-high temperature deuteric hydrothermal deposits). At the same time, higher content of hydrocarbon has been well preserved to present, even more than tens thousands uμl/kg.

首次系统地对各类矿石、岩石、矿物气液包裹体等进行了烃类组分分析，结果发现，各种金、银、锡、铅、锌、铜、锑等金属矿床(包括岩浆期后中高温热液矿床)的成矿过程均不同程度地存在有机物的参与，至今仍存在很高的烃气含量，甚至高达几万μl/kg。

Under scanning electron microscope,barite in these samples occurs as euhedral crystal,co-existing with authigenic quartz and albite with the same idiomorph.Considering the geological setting and c rystal form,it is believed that barite occurred in the study area is compara ble with that found in the Guaymas Basin,Gulf of California,i.e.,with hydrothermal origin.

通过对东太平洋多金属结核中国开辟区表层沉积物和短柱状沉积物的系统观察和分析，首次根据矿物学和地球化学两方面的证据，发现中国开辟区沉积物中热水活动及其产物的存在。X射线衍射分析表明，沉积物样品中普遍含有重晶石，部分样品中含量高达10%以上。

Of Fe , Cu in the metal phase and Mg, Si in the silicate phases to understand the processes of mixing of metal and silicate phases and further decipher the mechanism of formation of mesosiderite;(2) to study in detail the geochemical characteristics of each phase in the meteorite, to provide necessaryevidence for the model of formation of mesosiderite;(3) to study and update in detail the composition of each phase in the meteorite, and provide a new and complete set of data for understanding the mechanism of formation of mesosiderite.

Cu和硅酸盐相中的Mg， Si等中等挥发性元素的稳定同位素进行分析，判断中铁陨石的金属相和硅酸盐相混合过程的环境特征，进而阐明中铁陨石的形成机制；（2）对这块陨石的各相进行详尽的地球化学分析，通过这些相的地球化学关系判断中铁陨石的形成机制，对中铁陨石的形成模型提供必要的制约和证据；（3）全面更新对中铁陨石各矿物相化学成份的认识，为中铁陨石的成因之谜的全面揭开提供最新最完整的数据。

In the initial stage of the bioleaching, when the bacteria are not active, the chemical oxidation of ferric irons to the solid sulfide minerals is primary; While in the whole course of the bioleaching, it is very limited; ferric irons inhibit the bacterial activity, lower the oxidational ability of the bacteria to ferrous irons in the liquid phase; ferric irons and their precipitations reduce the quantities of the attached bacteria and their activity, and have bad influence on the direct bioleaching action.

结果表明，在浸出的初始阶段，Fe3+的化学氧化作用是主要的；但在整个金属浸出过程中，Fe3+的化学氧化作用是很有限的；Fe3+对T.f菌有一定的抑制作用，降低了它们对液相中Fe2+的氧化能力；Fe3+及其沉淀使细菌在固体矿物颗粒表面的吸附量减少，降低了吸附细菌的活性，从而影响了细菌的直接氧化浸出作用。

The paper expatiated the physical characters and mechanical performances of the composite material slabs synthesized by one, two, three or four minerals namely mica, mica + calcite, mica+ pyrophyllite + calcite or mica + calcite + pyrophyllite + periclase. It is concluded that the quality of the composite material consist of multiple minerals is better than the single material.
