矿产实物地质资料的筛选分级是实物地质资料采集、收藏的必要环节。本文在前人研究的基础上,引入模糊综合评价法,以地质特征、成矿背景和经济特征3类8项为评判因素,建立矿产实物地质资料的筛选分级评判模型。同时,以我国典型锡矿床为例,根据锡矿床的成矿背景、成矿区(带)、成矿时代、成因类型等资源分布特征,采用模糊综合评价法对锡矿实物地质资料进行筛选分级。结果表明,利用模糊综合评价法进行筛选分级是一种较为有效的手段。 相似文献

中国锰矿资源具有资源量丰富、矿床规模小、分布不均、品位普遍较低、成因类型复杂、成矿时代跨度大、对外依存度高等特点。截至2016年底,国内锰矿(矿石)查明储量为15.51亿t,矿床数量庞大,产生了大量实物地质资料。基于中国锰矿资源现状,结合实物地质资料的筛选原则,本文总结了国家级锰矿的筛选条件,即矿床规模大、品位高、成因典型,分布在重点成矿区或主要成矿时代和其他入选条件,并在全国范围内初步筛选出35个符合国家实物地质资料馆收藏的锰矿目录,反映了中国锰矿的成矿特点,为系统开展锰矿实物地质资料采集提供了科学依据和服务支撑。 相似文献

中国钼矿资源现状及国家级钼矿床实物地质资料筛选 总被引:1,自引:0,他引:1
根据中国钼矿床的成矿类型、成矿规模、成矿时代和分布等特点,简述了我国钼矿资源现阶段状况,提出了我国钼矿床实物地质资料筛选需要考虑的条件。结果表明:我国钼矿床类型多,以斑岩型为主,矽卡岩型次之,热液脉型、沉积型、海相火山岩型较少;我国钼矿床规模大,现阶段勘探、开发的矿床以大型、超大型矿床为主;钼矿床的成矿时代以燕山期成矿为主,其次为喜山期、印支期和海西期;钼矿床资源分布广泛,相对集中在燕辽、东秦岭、小兴安岭-张广才岭和大兴安岭4个钼矿矿集区。根据我国钼矿资源特点,结合国家实物地质资料馆馆藏规划,提出了当前符合国家实物地质资料馆收藏保管的34个钼矿床名录。 相似文献

在已有中国锡矿床科研成果的基础上,对中国102个中型及以上规模锡矿床进行了系统地归纳与总结。在成矿地质条件的基础上,按成矿作用的特点,再根据主要矿物的组合和蚀变特征,可将中国主要锡矿床分为热液型、夕卡岩型、变花岗岩型、云英岩型、斑岩型、伟晶岩型和砂矿型7种类型,其中热液型、夕卡岩型和砂矿型为主要矿床类型。锡矿床的主要成矿时期为燕山期,主要赋矿岩系为三叠纪的灰岩、大理岩系。结合主要矿床的品位模型,可以发现产于燕山期花岗岩中的热液型锡矿床和夕卡岩型锡矿床是今后主要的找矿类型及方向。 相似文献
