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。
The Nakagawa region has experienced three stages of toughness, brittleness and ductility, and brittle deformation, and suffered three magmatic intrusions in three phases. The Liba gold deposit is a moderate-low-temperature epithermal-magmatic reconstituted ore deposit. Its source rock is mainly deposited in the Late Paleozoic. The mineralization process has undergone an early stage of activation and migration of gold elements. During the transformation stage of the tectono-hydrothermal mineralization and printing Branch - Yanshanian magmatic rejuvenation stage. The regional deep faults are the main channel of the metallogenic thermal cycle. The ore-forming fluid is dominated by atmospheric precipitation, and part of the magmatic fluid is involved in metallogenesis.
