Structuresteep east-dipping faults, The area has been affected by regional thrust faulting.
AlterationAlteration includes decalcification and weak silicification in siltstone, and formation of massive jasperoid in the upper part of the limestone unit. Alteration of dikes is mainly sericite-quartz-pyrite, with late pyrite-quartz-kaolinite.
