Zhongchuan area underwent ductile→ductile-brittle→brittle deformation with 3 periods and 5 times of magmatic intrusion. Liba style Au deposits are medium-low epithermal-magma reworked deposits. Late palaeozoic sedimentary formations are the source beds. Ore formation included the early Au mobilization and transportation, tectonic-hydrothermal rework and Indo-China-Yanshanian magmatism rework. The regional deep fractures are main conduit of ore fluid which is dominated by meteoric water.%中川地区历经了韧性→脆韧性→脆性变形3阶段,遭受了3期5次岩浆侵入.李坝式金矿床为中低温浅成热液-岩浆再造矿床,其矿源层主要为晚古生代沉积建造,成矿过程经历了早期金元素活化迁移阶段、构造-热液成矿作用改造阶段和印支&燕山期岩浆作用再造阶段.区域性深大断裂是成矿热循环的主通道,成矿流体以大气降水为主,有部分岩浆流体参与成矿.
