Insights into the formation of the Dasuji porphyry Mo deposit (North China Craton) gained from mineral chemistry data

The Dasuji Mo deposit is located within the northern margin of the North China Craton. Based on vein cross-cutting relationships, mineral assemblages and alteration characteristics, the formation of the deposit can be divided into four stages: stage 1, consisting of two vein types developed in deep, is characterized by K-feldspathization with minor molybdenum mineralization; stage 2, containing four distinct vein types, is the main stage of...
