摘要
宁夏虽地域面积较小,但矿产资源种类众多,能源、金属、非金属、水气类矿产均有发现.已发现 60余种矿产(含亚矿种)中,获探明储量的矿产种类达 50余种,煤、石膏、灰岩、冶镁白云岩、硅石等为优势矿种.笔者总结了宁夏矿产资源的时-空分布演化规律:时间上分为元古宙、古生代、中生代和新生代4个时段.非金属矿在加里东期及喜马拉雅期、金属矿在晋宁期及燕山期、能源矿产在华力西期及燕山期、水气矿产在喜马拉雅期分别达到成矿高峰期.空间上以宁夏 12个五级(Ⅴ)构造单元为基本空间单元开展:金属矿产主要集中地即为贺兰山、卫宁北山、南-西华山地区.非金属矿产主要集中在贺兰山褶断带及香山褶断带中,其次为烟洞山-窑山冲断带,陶乐-彭阳冲断带.能源矿产在陶乐-彭阳冲断带聚集特征明显.水气矿产绝大部分聚集在银川断陷盆地内.在综合消化已有地质矿产资料的基础上,对宁夏全区划分 9个Ⅳ级成矿亚带及 19个矿集区或远景区,厘定9个矿床成矿系列及10个矿床成矿亚系列,并建立了区域成矿谱系.
Abstract
Although Ningxia is small in area,there are many kinds of mineral resources,including energy,met-al,nonmetallic and groundwater-gas minerals.More than 60 kinds of minerals(including subminerals)have been discovered,of which more than 50 kinds of minerals have proved reserves.Coal,gypsum,limestone,mag-nesia dolomite,silica and other dominant minerals.This paper summarizes the time-space distribution evolution of mineral resources in Ningxia:The time can be divided into Proterozoic,Paleozoic,Mesozoic and Cenozoic.The non-metallic minerals reached their metallogenic peak in Caledonian and Himalayan ages,the metallic min-erals in Jinning and Yanshanian ages,the energy minerals in Hualissian and Yanshanian ages,and the water-gas minerals in Himalayan ages.In space,12 grade Ⅴ structural units in Ningxia are used as the basic spatial units:Metal minerals are mainly concentrated in Helan Mountain,Weining North Mountain and South-West Huashan region.Non-metallic minerals are mainly concentrated in helan Mountain fold and Xiangshan fold,followed by Yandong Shan-Yaoshan thrust belt and Taole-Pengyang thrust belt.Energy mineral resources are concentrated in taole-Pengyang thrust belt.Most of the hydrogas minerals are concentrated in yinchuan fault depression basin.Most of the groundwater-gas minerals are concentrated in Yinchuan fault depression basin.On the basis of comprehensive digestion of existing geological and mineral data.The whole area of Ningxia is divided into 9 grade Ⅳ metallogenic subbelts and 19 ore clusters or prospective areas.Nine ore-forming series and 10 ore-forming subseries were determined and regional metallogenic genealogy was established.
