热液学说不能完全解释金属从岩浆 (或岩石 )中分离和富集的自然条件。酸性岩中包体研究表明 ,存在特殊的硅酸盐熔体卤水 (silicate saltmelt brine)相 ,它在熔体结晶早期即从中分离出来 ,其中富含盐类 (质量分数可达 70 %)、金属、水、F、Cl、B等。而实验研究显示 ,原始的酸性熔体在冷却过程中分裂为硅酸盐熔体 (silicatemelt)和熔体卤水 (melt brine) ,熔体卤水还可进一步分离出更多的熔体卤水系列 (melt brines) ,它们也富含金属元素。熔体中高度富集的流体是产生这一过程非常有利的条件。
The hydrothermal theory can not fully explain the natural conditions for the separation and enrichment of metals from magma (or rock). Studies of inclusions in acid rocks show the presence of a special silicate saltmelt brine phase, which is isolated early in the melt crystallization and is rich in salts (up to 70% by mass), metals , Water, F, Cl, B and so on. However, experimental studies have shown that the original acidic melt splits into silicatemelt and melt brine during cooling, and the melt brine can further separate more melt streams brines), they are also rich in metal elements. The highly enriched fluid in the melt is a very favorable condition for this process.
