| 中文摘要:吉林省地质历史演化复杂,构造岩浆活动强烈,成矿地质条件有利,百余年来矿产勘查成果丰富。为促进新一轮找矿突破战略行动,提升国家战略物资储备保障能力,采用矿床的成矿系列理论对吉林省成矿规律及找矿方向进行了研编。研究表明,吉林省可划分5个Ⅲ级成矿区带,11个Ⅳ级成矿亚带,29个矿集区。松辽盆地石油—天然气—铀成矿区(Ⅲ-51)为一规模较大的中新生代沉积盆地,可划分为1个成矿系列、2个成矿亚系列、4个矿床式,油页岩为优势矿产。小兴安岭—张广才岭成矿带(Ⅲ-52)及吉中—延边成矿带(Ⅲ-55)范围为吉黑造山带一部分,可划分为12个矿床成矿系列、21个亚系列、39个矿床式,优势矿产为金、钼、镍；辽东(隆起)成矿带(Ⅲ-56)覆盖范围为吉南龙岗地块,划分为10个矿床成矿系列、15个亚系列、27个矿床式,金、铁、镍铜、钴铜、石墨、硼、硅藻土为优势矿产。 |

| Abstract:自己The geological history of Jilin Province is intricate, marked by robust internal tectonic-magmatic activity and favorable metallogenic geological conditions. Over the past century, significant strides have been made in mineral exploration, yielding substantial achievements. In accordance with the National Exploration Development Plan and with the aim of bolstering the capacity of the national strategic material reserve, the metallogenic regularities and prospecting directions of Jilin Province are investigated through the application of the minerogenetic series theory. The results show that Jilin Province can be divided into 5 grade Ⅲ metallogenic belts, 22 grade Ⅳ metallogenic sub-belts and 29 ore concentration areas.The oil-gas-uranium metallogenic area (Ⅲ-51) in Songliao Basin is a large Mesocenozoic sedimentary basin. It can be divided into 1 metallogenic series, 2 metallogenic sub-series and 4 deposit models. Its dominant mineral is oil shale. Its prospecting direction is Changchunling model. The Xiaoxinganling-Zhangguangcailing metallogenic belt (Ⅲ-52) and Jizhong-Yanbian metallogenic belt (Ⅲ-55) are part of the Jihei orogenic belt, which can be divided into 12 metallogenic series, 21 sub-series and 39 deposit models. The dominant minerals in Ⅲ-52 metallogenic belt are gold and molybdenum, and the prospecting direction for gold is Xiaoxinanzhan model, Jiusanggou model, and Zuizigou model. The dominant minerals in Ⅲ-55 metallogenic belt are gold, molybdenum and nickel. The gold prospecting direction is Lanjia model, Erdaodianzi model, Songjianghe model and Haigou model. Nickel prospecting direction is Hongqiling model, molybdenum prospecting direction is Daheishan model, Dashihe model, Shengli tun model, and Shimadong model. The East Liaoning Uplift metallogenic belt (Ⅲ-56), located in Nanlonggang area, can be divided into 10 metallogenic series, 15 sub-series and 27 deposit models. Gold, iron, nickel copper, cobalt copper, graphite, boron, and diatomite are the dominant minerals. From the perspective of prospecting direction, the gold’s is the Jiapigou model, the JinChanggou model, the Huanggoushan model, the Jinying model, the Xiangluwanzi model; Iron’s includes Anshan model, the Wudaoyangcha model, the Dalizi model, the Linjiang model, and the Hunjiang model; Nickel copper’s is the Chibaisong model; Cobalt copper’s is the Dahenglu model; Graphite’s is the Shuangxing type; Boron’s is the Gaotaigou model; Diatomite’s is Maanshan model. |
