摘要
赣北地区包括长江中下游成矿带(江西段)和江南成矿带(江西段)。江南成矿带(江西段)钨矿床自南东侧至北西侧成岩成矿时代逐渐变轻160 Ma→150~140 Ma→135~125 Ma,其中主成矿期为150~140 Ma、135~125 Ma;控矿构造以NE向构造及其次级裂隙为主,成矿浆岩包括Ⅰ型和S型,以S型为主。区内成矿系列包括与S型酸性岩浆活动有关的钨锡银铅锌铀钍矿床成矿系列和Ⅰ2型中酸-弱酸性斑岩有关的钨、钼矿床成矿亚系列。将江南成矿带(江西段)钨矿自南至北划分为朱溪、大湖塘、阳储岭、香炉山-东坪、莲花山等5个矿集区。
Diagenetic and metallogenic ages of tungsten deposits in Jiangnan metallogenic belt(Jiangxi Section)gradually lightened from south to north,from 160 Ma to 150~140 Ma to 135~125 Ma, with the main metallogenic periods being 150 ~140 Ma and 135 ~125 Ma;NE trending structures and secondary fractures are theore-controlling structures.Metallogenetic magma geochemicallybelongs to Ⅰ-type and S-type, the latter being more prominent. Metallogenic series include W-Sn-Ag-Pb-Zn-U-Th deposits related to S-type acidic magmatism and W-Mo metallogenic subseries related to Ⅰ2-type intermediate acid porphyry. Tungsten distribution in Jiangnan metallogenic belt(Jiangxi Section) canbe further divided into five ore districts from south to north, namely Zhuxi,Dahutang, Yangchuling, Xianglushan Dongping and Lianhuashan.
