- Abstract
Volcanic type uranium deposit is an important type of hydrothermal uranium deposits in China. The deposit occurs in the volcanic basin of the regional volcanic eruption belt and controlled by combination of tectonic-lithology lithofacies-hydrothermal circulation. The structural form can reflect the properties of volcanic facies and hydrothermal fluid, and reflect the characteristics and internal laws of volcanic hydrothermal uranium mineralization. The volcanic type uranium deposits can be divided into four subtype: volcanic breccia tube, subvolcanic rock, dense fracture zone and interlayer fracture zone. This paper expounded the developing patterns of different subtypes by the volcanic hydrothermal activity from the volcano center to the far source, established a comprehensive metallogenic model of volcanic rock type uranium deposits in China and summarized the metallogenic geological conditions of different subtypes of uranium deposit(structure, lithology, lithofacies, host rock), the mineralization and genesis(metallogenic fluid,metallogenic temperature, mineralization depth, mineralization characteristics ore body shape, ore minerals, associated elements) characteristics in geophysics, geochemical exploration, remote sensing etc. This model will benefit the selection of effective technical methods in the prediction and prospecting practice of volcanic type uranium deposit at different basin parts or environments.
