The eastern and western sides of the Yunkai block are bounded by the northeast of Wuchuan-Sihui fault and Bobai-Cenxi fault, Proterozoic experienced a multi-period structure, magmatic effect. The strata exposed in the area are mainly the Neoproterozoic Yunkai Group metamorphic rocks, the Caledonian mixed rocks and the Lower Paleozoic strata.
