From the study of the inclusions in the mineral fissures, the paper indicates that theore-forming fluid from the ductile shear belt type gold deposits in Huangtuling are low salinity(<10 %),moderate temperature (192~274 ℃) high sulphur, rich in HCO3, Cl-and base cations.There are three types of fluid inclusions: CO2,CO2-H2O and H2O. They coexist in minerals andhave different salinities and densities. This shows that the phase separation and effervescence occurred when the inclusions were trapped.The isotopic...

From the study of the inclusions in the mineral fissures, the paper indicates that theore-forming fluid from the ductile shear belt type gold deposits in Huangtuling are low salinity(<10 %),moderate temperature (192~274 ℃) high sulphur, rich in HCO3, Cl-and base cations.There are three types of fluid inclusions: CO2,CO2-H2O and H2O. They coexist in minerals andhave different salinities and densities. This shows that the phase separation and effervescence occurred when the inclusions were trapped.The isotopic compositions of the water in the inclusionindicate that the hydrothermal solution is mainly metamorphic water,mixing with some rain water and geothermal water. It is considered that the key factors of gold mineralization are phaseseparation and effervescence. So abundant CO2 inclusions,and high CO2 and sulphur in fluids canbe used as good exploration guides to the gold deposits.

包裹体研究表明,河南鲁山黄土岭韧性剪切带型金矿的成矿流体为低盐度、中低温度、高硫、富HCO和Cl-及碱金属离子的热流体。包裹体类型有CO2,CO2-H2O及H2O三种,它们在矿物中共生,并且各自的密度、盐度有区别,表明包裹体捕获时流体发生过沸腾作用,有过相态分离。包裹体水同位素研究结果显示热液以变质水为主,混有一定量的岩浆水与雨水。沸腾作用、相态分离是矿床形成的关键因素。CO2包裹体大量出现、流体中CO2的高含量、富硫等是这类矿床的找矿标志。

A new buoyancy salinometer sultabe for field tal laboratory uses has been dCsigned and made in 1995. ms instrumnt is charterised by low cost, simple construction and high reliablity. Its main advantages include simple operation and fast determination; no power source, chemical agent and standard correction before determination are needed Its accuracy of measurement is immune to the interference by suspended material and seawarer constituent variations. this method is accurate to 0.02, the same as tha of the Kundsen method. The Present experiment shows that the salinity derived using the salinometer is correct with the seawater temperature ranging from 0 to 35℃. The buoyancy salinometer can be applied to the monitoring of surface seawater salinity in nearshore, estuarine and mariculture areas. 1 Principle and apparatus The priociple of buoyancy salinometer is based upon the intermlationships betWeen buoarey, density and salinity. For a buoyancy meter with given volum and weight the buoyancy is related to the density of seawater which is influenced by the seawater temperature and salinity. If the temperature is known. the salinity can be determined. The buoyancy salinometor consists of a buoyancy meter, a centigrade thermometer, a slide salinity ruler, a ruler for correcting the temperature effect, a sampling volummer and a safeguarding device for the buoyancy meter. Three salinity rulers can be used for the salinity ranges of 0-16, 16-32 and 32-48, respectively. These are matched by thee rulers for uses with temperature of 0-35℃. 2 Calibration The water level line is applied to Calibrate the basic possition for the temperature ruler. 3 The working curve The working curve of the buoyancy salinometer (Fig.1) shows tha the buoyancy salinometer has a satisfactory responsibility for a salinity range of 0-48. 4 Precision and accuracy The precision and accuracy were determined by Beihai Brach of the State Stabdard Measure Center. The data shown in Tables 1 and 2 are satisfactory for salinity measarements using the buoyancy slinometer.
