Abstract:
According to field geological survey, rock sampling, and analysis of former geological, geochemical, geophysical data, the mineralization characteristics and prospecting potential of uranium in the Keke region is probed. It is found that F4 thrust fault and F5 normal fault controlled the distribution and size of uranium deposits in Keke region, mica-quartz schist is the wallrock of uranium mineralization, metamorphic quartz sandstone is one of most rich uranium-hosting rock series, red alteration in metamorphic sandstone is the most obvious uranium guide of prospecting. It is also found that the pegmatite dikes, lamprophyre dikes and diorite-porphyrite dikes are significantly related to uranium mineralization, and are also core guide of uranium prospecting. It is thought that the most prospecting potential zone lies between the downthrow of F4 reverse fault and hanging wall of F5 normal fault.
