| 摘 要： | 随着找矿的深入,在鲁中东-苏西北地区新发现了一批大中型金、铁和金刚石矿床,该区已成为我国重要的矿产资源基地。本文在新的研究成果和认识基础上,通过综合分析,在该地区划分新的重要成矿部署区带,厘定边界并命名为"鲁中东-苏西北Au-Fe金刚石成矿带",初步建立了该成矿带成矿谱系,结果显示成矿带内存在太古宙、元古宙、古生代、中生代以及新生代等5期成矿。区内矿产以金、铁以及金刚石为主,金矿床类型主要有石英脉型、破碎蚀变岩型,铁矿类型主要有沉积变质型和矽卡岩型,金刚石矿主要为岩浆型。结合研究区找矿最新进展和全国矿产资源潜力评价最新成果,认为本区Au、Fe、金刚石资源潜力巨大。在此基础上划分了6处远景区,为进一步实现找矿突破及地质找矿战略部署提供了科学依据。

| Abstract: | With deepening of prospecting work, a number of large medium scale gold, iron and diamond deposits have been found in the area bounded by central eastern Shandong and northwestern Jiangsu provinces, making it an important mineral resources base. On the basis of the latest research results and comprehensive analysis, this study re defined the metallogenic zones for this area, which was named the Luzhong Suxibei Au- Fe- diamond metallogenic belt. The metallogenic lineage was also established. The study results show that five metallogenic stages occurred in this belt, mainly in the Archaean, Proterozoic, Paleozoic, Mesozoic and Cenozoic epochs. Minerals in the belt are dominated by Au, Fe and diamond. The gold deposit types include quartz vein type and altered rock type; the iron deposit types are sedimentary metamorphic type and skarn type; the diamond deposit type is only magmatic type. Geological prospecting progresses and national mineral resource potential assessment project indicate that Au, Fe and diamond are of big resource potential. Six metallogenetic prospective areas are divided for further guidance exploration deployment, thereby providing a scientific basis for mineral prospecting. |
