即铀含量较高的晚期二云母过铝质花岗岩是铀成矿作用的铀源，而且，铀源主要来源于被风化并剥蚀掉的那部分母岩，而不是来源于热液流体对现存母岩的交代。

The 40Ar/39Ar geochronologic study indicates that with the ratio 40Ar/39Ar in atmosphere which changes with time,the time and strength of degassing of the earth can be probed,and that the 40Ar/39Ar dating method can help researchers study not only crust mantle evolution and the history of magma dynamics during the cooling process and granitoid emplacing, but also the hydrothermal ore deposit dating.

研究表明：可以通过大气中40Ar/39Ar比值随时间的变化窥探地球去气作用的时间和强度；40Ar/39Ar法不仅有助于研究岩浆冷却过程和花岗岩侵位机制等岩浆动力学的历史和壳幔演化，而且对研究热液成矿年龄也是很有效方法之一；在一定的地质条件下，沉积地层时代越老，40Ar/39Ar值越高；当今40Ar/39Ar年代法已为全球环境演变研究提供了一种强有力的工具。

The temperature of the heated seawater must be less than 150℃.(2) Anhydrite precipitation within the large deposit is mainly controlled by the seawater heating process and the mixing process of hydrothermal fluid and entraining seawater.
