中国东南部的赣南、湘东南、湘南、粤北、桂东北是全球罕见的世界级多金属成矿带—南岭有色金属成矿带,区内有色、贵金属成矿事件集中于中生代,明显与中生代构造-岩浆活化密切相关。近年来,中生代岩浆活动、成矿过程及其机制研究已成为我国地学领域的前沿和热点,但尚未取得共识。南岭地区构造层可分为南华纪-志留纪地槽构造层、泥盆-中三叠纪地台构造层、晚三叠纪-新生代地洼构造层三个部分。大量的同位素测年数据证实南岭地区中生代岩浆岩主要为印支期、燕山早期和燕山晚期
Southeast Jiangxi, southeastern Hunan, southern Hunan, northern Guangdong and northeast Guangxi are the world-class non-ferrous metallogenic belts in Nanling, a rare world-class polymetallic metallogenic belt in the southeastern China. The occurrence of non-ferrous and precious metal mineralization in the area concentrated in the Mesozoic, It is closely related to Mesozoic tectono-magmatic activation. In recent years, Mesozoic magmatic activity, mineralization process and its mechanism has become the forefront of geosciences and hot spots in China, but no consensus has yet been reached. The Nanling area structural strata can be divided into three parts: the Nanhuaji-Silurian terrane structure layer, the Devonian-Middle Triassic platform structural layer and the Late Triassic-Cenozoic depression structural layer. A large number of isotope dating data confirm that Mesozoic magmatic rocks in the Nanling area are mainly Indosinian, early Yanshanian and late Yanshanian
