四川省会东县金锁桥铁金矿床位于杨子地台西缘川滇黔铜多金属成矿带,地处环太平洋构造域和特提斯构造域的结合部位,川滇黔菱形地块之会理-昆明裂陷带。该区经历了自早元古代弧后盆地、早中元中代拗拉槽、中元古代陆内裂谷、中晚元古代大陆边缘陆弧体、晚元古代后造山裂谷、古生代块断升降、地裂运动及中生代前陆盆地和山间断陷等漫长的地史演化,是以前震旦系变质岩作基底、古生代海相沉积作盖层的长期隆起地带,具地槽型变质岩系活动带及地台沉积。构成了本区良好的成矿
The Gold Lock Bridge iron-gold deposit in Huidong County, Sichuan Province is located in the copper-polymetallic metallogenic belt of the Sichuan-Yunnan-Guizhou border on the western margin of the Yangzi platform. It is located at the junction of the Pacific Rim tectonic domain and the Tethyan tectonic domain. The Sichuan- Huili - Kunming rift zone. The area has experienced a series of geological processes since the Early Proterozoic backarc basin, the Early Middle and Middle Proterozoic Durassic slot, the Proterozoic intracontinental rift, the mid-late Proterozoic continental margin arc body, the Late Proterozoic post-orogenic rift, Paleozoic block Ascending and descending, ground-fissure movement and the long historical evolution of the Mesozoic foreland basin and fault depression in the mountains are long-term uplifts of the former Sinian metamorphic rocks underlain by basement and Paleozoic marine sediments. Belt and platform deposition. Constitute a good area of mineralization
