摘要
The Fanchang Basin is the natural laboratory to study internal relations and time-space relations of the Mesozoic tectonism-basin formation-magmatism-mineralization in East China. The Fanchang Basin at the southern margin is located within the knot of the Middle and Lower Yangtze River,which has three tectonic ore-controlling characteristics: 1) the Tongling-Nanling Fault Zone is the first-order ore-controlling structure; 2) the Yanshanian superimposed folds are the secondary-order ore-controlling structures which controls the transportation and emplacement of the hydrothermal ore-forming solution; and 3) the geologic bodies containing ores are third-order ore-controlling structures,some ideal spaces for ores transportation and accumulation.The Indosinian and Yanshanian tectonic movements provide favorable channels and emplacement spaces for the transfer of the Yaojialing polymetallic mineralizied fluids:1) rock-transporting structures; 2) ore-transporting structures; and 3) ore-accumulating structures.
