摘要
The Luzong Mesozoic volcanic basin is located in the Lower Yangtze River fault-depression zone, where is the northern margin of the Yangtze Block. The volcanic and intrusive plutons occur widely in Lu-Zong Basin, including four formations of volcanic rocks such as: Longmenyuan Formation, Zhuanqiao Formation, Shuangmiao Formation and Fushan Formation and 34 intrusive plutons. A lot of metallic and nonmetallic deposits such as iron, copper, gold, lead, zinc, uranium, alunite and anhydrite deposits orrur in the basin. The acid alteration widely developed in the north part of the basin, indicating the existence of high sulfidation epithermal hydrothermal system.
