On the basis of an analogy and analysis of the metallogenic geologic conditions,geochemistry and microelement between domestic typical medical stone and that of Jiangxi Province,the author have pointed out the prospecting direction for medical stone s in Jiangxi Province.

通过对国内典型麦饭石矿与江西省麦饭石矿的成矿地质条件、岩石化学及岩石微量元素等特征的类比和分析，提出了江西省麦饭石矿的找矿方向。

JIANCHALING Ridge gold deposit and ultrabasic rocks in space-time and on the causes are closely related, in the Qinling Mountains in the Orogen is the first in China is rare type of gold deposits, to its unique geological background and characteristics of mineralization is important Significance of the study.

煎茶岭金矿床与超基性岩在时空和成因上具有密切关系，在秦岭造山带中尚属首例，在我国也是少见的金矿床类型，其独特的地质背景和成矿特征具有重要的研究意义。

A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

The relationship of ore-forming fluid salinity-aqueous cation lg demonstrated that water-rock reaction was also one of the potential gold deposition mechanisms besides mixing with meteoric water. All of these were consistent with that sericitization and pyritization hydrothermal alteration were extensively/intensively distributed (as high as 33%), gold grade linearly correlated with degree of alteration,∑REE depletion and δ〓O enrichment

成矿流体盐度-液相主要阳离子组分1g演化规律研究表明，除与大气降水的混合-稀释外，水-岩相互作用也可能是造成金沉淀的重要因素，这与本文所研究金矿床中绢云母化、黄铁矿化等热液蚀变广泛发育(可高达33％)，Au品位与热液蚀变程度、REE亏损量及δ〓O富集规模表现出较为明显的线性关系等一系列地质事实相吻合
