Palaeoexogenous ground water runoff in a typical uranium orefield in Jiangxi Province
After restoring the paleotopography and regional groundwater paleocurrent field of a uranium orefield in Jiangxi,the meas-ured pressure data of gas-liquid inclusions of two typical samples were used to invert the topography of the liquid recharge zone in the inclusions,reaching the conclusion,namely,that the exogenous water in the convective mode could not enter the high-pressure magma in the metallogenic period.The results of hydrogen and oxygen isotope testing of 9 mineral fluid inclusions in the mining area show that water in the inclusions partly came from atmospheric precipitation.In addition,temperature measurement data of fluid inclusions invol-ving 10 magmatic inclusions and exogenous water,as well as the relative position of the distribution of regional deposits and paleovolca-nic craters,can also prove that part of the water in the ore fluid came from paleoexogenous water,and the paleoexogenous water under-went"turbulence"during the mineralization process.
