The Kunduleng pluton is relatively diminutive in comparison to numerous other plutons, with dimensions of approximately 14 km along its longest axis (NE-SW), 3 km along its shortest axis (NW-SE) and covering an area of about 42 km2. The granite intruded into the intermediate to acid volcanic rocks of the Early Permian Dashizhai Formation and the rhyolitic pyroclastic rocks of the Late Jurassic Manketouebo Formation. Subsequently, it was overlain by the rhyolitic lava flows and welded tuffs of the Early Cretaceous Baiyingaolao Formation. The predominant lithology of the pluton consists of massive, porphyritic, medium- to coarse-grained granite with a pale red color. There are four locations of high radioactive anomalies within the Kunduleng pluton. The anomalous area is about 3 km2 in total, accounting for 7% of the surface exposure of the granite pluton. Detailed examination of the identified uranium anomalies found they were confined to the area characterized by well-developed joints. In the vicinity of joints, these granites frequently undergo varying degrees of hydrothermal alteration, leading to the formation of reddish altered rocks containing elevated concentrations of radiogenic elements.
