The system of deposit formation established on the basis of geological phenomenon only possesses some properties and possibilities. Modern principles of deposit formation have been concerned in the essential problems graduully.The stress of research, however,is mostly put on the inspection of reactionary mechanism and its balanced conditions. But the fundamnental mechanism of deposit formation is the separate effect of ma terial constituents.Grounded on the theory of thermodynamicof irreversible processes, it is possible to dig up the separate effect of individual field in a process of deposit formation, such as gravitation field, temperature field, electric field, pressure field, and so on.Then we can obtain the separate effect of composite field on this basis. For example, the constituents with high specific gravity and high ion electric potertial(such as Fe~(3+),Fe~(2+),Cu~(2+),Cr~(3+), etc.) will concentrate favorably, where low pressure and low electric potential superpose each other. But the constituents with low specific gravity and low ion electric potential (such as[Co_3]~(2-),[Si_4O_(10)]~(4-),[AlSi_3O_8]~(1-),etc.)will concentrate favorably,where high pressure and high electric potential superpose each other.

建立在现象基础之上的成矿规律,只能具有某种特殊性与可能性。现代成矿原理已逐渐深入到本质问题方面,但是多侧重于反应机制与平衡条件的分析研究。而成矿作用的根本机制却在于物质组分的分离效应。 根据不可逆过程热力学的基本原理,分析成矿过程个别场的分离效应,如重力场、温度场、电场、压力场等;并在此基础上得出综合场的分离效应,如在低压力与低电位迭加空间最利于比重大离子电位高的组分富集(如Fe~(3+),Fe~(2+)、Cu~3+)、Cr~(3+)等等);而在高压力与高电位迭加空间则利于比重小离子电位低的组分富集(如[co_3]~(2-)[Si_4O_10]~(4-),[AlSi_3O_8]~(1-)等等)。

The content of gold and silver in natural gold ore was measured by the spectrum analysis in the gold deposits with different genetic types.Calculated the ratio between gold and silver of each natural gold grain,the continuous curves of gold and silver ratio are drawn to objectively reflect the metallogenic regularities and conditions of ore forming process of gold ores.The analysis supply a new tool for the geologic investigation and prospecting...
