Plenty of gold deposits related to Late Mesozoic craton destruction are widely distributed in eastern North China Craton.However,significant differences in research degrees,ore-forming characteristics,and proven reserves exist among different regions in the North China Craton.The Liaodong Peninsula has similar regional geological characteristics to those of the Jiaodong Peninsula,with both experiencing craton destruction during Late Mesozoic,but the two areas have substantial differences in terms of gold mineralization and the proven gold resources.Based on regional geology,Mesozoic magmatic-tectonic evolution and ore geology,combined with integrated geophysical exploration and big data AI resource prediction,in this paper,we propose that the ore-forming materials of Late Mesozoic gold deposits in Liaodong were mainly originated from mantle-derived melts and/or fluids induced by craton destruction.The gold deposits were primarily controlled by NE-NNE-trending faults,mainly classified as fracture-controlled altered rock-type and sulfide-bearing quartz vein-type.Moreover,our study predicts that the Yalu River fault zone and its related secondary faults,as well as the periphery and deeper parts of known goldfields,are the important regions for future gold resource exploration.The Yalu River metallogenic belt has an enormous potential for gold resources,and the Liaodong Peninsula has a potential to add thousands of tons of gold resources.
