摘要
Xinlu volcanic basin is not only a significant base for uranium production but also the only uranium ore district for exploration in Zhejiang Province at present. According to the geophysical deep profile, the relatively low velocity fluid occurs at the depth of -40 km, and the relatively high-velocity magma intrusion occurs in upper strata. There are four magmatic cycles from Mesozoic in the study area. There are also three tiers of stratigraphic configuration showing the obvious hotspot action with the lower tier being metamorphic basement, the middle tier being slippage strata, and the upper tier being lava and Cretaceous sediments.
