    摘要:

    辽东-吉南成矿带是2008年确定的首批16个重要成矿带之一,随着新的找矿进展和预测成果不断涌现,需要对其开展新一轮研究总结。本文以新的研究成果和找矿突破为基础,通过综合分析,将其命名为“辽东-吉南Fe- 菱镁矿- Cu-Au成矿带”并对其开展成矿作用类型及勘查部署综合研究。该区带范围与III级成矿带辽东(隆起)Fe- Cu- Pb- Zn- Au- U- 硼-菱镁矿-滑石-石墨-金刚石成矿带一致,结合区域成矿地质背景、成矿作用类型及典型矿床的综合研究,初步建立了辽东-吉南Fe- 菱镁矿- Cu- Au成矿带成矿谱系,并将其主要成矿期归纳为三期:新太古代、古元古代和中生代燕山期;在典型矿床成矿地质特征及潜力评价综合分析的基础上,总结了研究区主要成矿类型为沉积变质型铁-菱镁矿、火山沉积-变质改造型铜锌矿、沉积变质-叠加改造型铅锌矿、岩浆型铜镍硫化物矿、岩浆热液型金矿以及造山带型金矿。结合区域找矿进展和潜力评价最新成果,认为本区Fe、菱镁矿、Cu、Au潜力巨大,为下一步勘查部署的主攻矿种,同时在本区划分了12个远景区,其中10个为重点远景区,2个为远景调查区,对研究区下一步矿产勘查部署工作有一定指导意义。

    Abstract:

    The Liaodong Jinan metallogenic belt, which is one of the 16 important metallogenic belts first specified in 2008, needs new research about the metallogenetic potentiality and boundary delimitation. Based on the new research results, this paper proposed suggestion for exploration deployment through comprehensive analysis and named the belt the Liaodong Jinan Fe- Mg- Cu- Au metallogenic belt. The range of this metallogenic belt is consistent with that of the eastern Liaoning (uplift) F-e Cu- Pb- Zn- Au- U- B- Mg- talc- graphite- diamond metallogenic belt. Combined with the comprehensive analysis about regional geology setting, mineralization type and typical deposits, we preliminarily established the metallogenic pdigree of this metallogenic belt and summed the metallogenic epoch into three stages: Neo archean, Paleoproterozoic and Yanshanian in Mesozoic. The main metallogenic types in study area are: sedimentary metamorphic iron magnesite ore, volcano sedimentary metamorphic reformed copper zinc ore, sedimentary metamorphic superposition remould Pb Zn, magmatic Ni Cu sulfide ore, magmatic hydrothermal type gold and orogenic gold deposit. It is also pointed out that Fe, magnesite, Cu, Au are leading minerals for the next research in study area. In addition, this research also determined 12 prospect areas in the Liaodong Jinan Fe- Mg- Cu- Au metallogenic belt and 10 of those are key areas. This study may guide the next exploration deployment work effectively.
