摘要
Abstract
The measurements of oxygen and hydrogen isotopic com position for minerals and liquid inclusions in minerals show that theδ1 8O andδD values for ore-forming hydrothermal solution in the Xiangshan uraniu m or e-field range from -9.8‰～+1.8‰(SMOW) and -45.0‰～87.1‰ (SMOW) respectively. The variation of δ18O values in the altered system reveal that the w ater reacted with rocks in the field is of low-δ18O meteoric characterist ics. Under the conditions of different water/rock ratios, the theoretical calculatio ns for the equilibrium water-rock isotopic exchange reactions indicate that the U ore-forming fluid originated from paleo-meteoric water-rock interaction during the mineralization epoch instead of magmatic origin.关键词
