Abstract

Abstract

The authors studied the regional geological setting and metallogenic characteristics of the Xiangshan ore field and analyzed the sources of ore substances and ore fluids and channels for transport of ore substances, and on that basis, they constructed a uranium metallogenic model for the Xiangshan ore field. Uranium metallogenesis of the Xiangshan ore field took place in a specific temporal-spatial domain controlled by the regional geological setting; regional uranium-rich strata provided substances for metallogenesis; and ore fluids derived from magmatic water, mixed meteoric water, magma and postmagmatic hydrothermal fluids were carriers of uranium transport. The uranium metallogenic model emphasizes that the formation process of volcanic rocks was a process of ore substance concentration. The evolution of the volcanic postmagmatic hydrothermal ore system gave birth to ore-forming processes with a time span of 50 Ma in the Xiangshan volcanic basin. The coupling of metallogenic mechanisms such as temperature decline, concentration and mixing of fluids promoted uranium precipitation and ore formation.
