中国菱镁矿成矿地质特征与资源潜力
|
摘要
国土资源部为了基本摸清全国重要矿产资源"家底",为矿产资源保障能力和勘查部署决策提供依据,开展了全国重要矿产资源潜力评价项目。菱镁矿是开展的25个重要矿种之一。本项目的实施,是我国矿产资源方面的一次重要的国情调查。本次工作以成矿地质理论为指导,深入开展区域成矿规律研究;充分利用地质、物探、化探、遥感和矿产勘查等综合成矿信息,建立典型矿床预测模型和区域预测模型,圈定成矿远景区和找矿靶区;充分应用现代矿产资源预测评价的理论方法和GIS评价技术,逐个评价其成矿远景区资源潜力;用地质-体积等多元信息方法估算了地下2 000m以浅的菱镁矿资源量,为科学合理地规划和部署矿产勘查工作提供依据。中国菱镁矿主要成矿时代为古元古代,成矿类型以沉积变质型为主,全国共有累计查明资源储量(矿石量)36.42亿t,主要分布于辽宁、山东和新疆。全国共圈定菱镁矿最小预测区129个,获2 000m以浅预测资源量(矿石量)131亿t。全面总结并建立了菱镁矿典型矿床预测模型及区域预测模型,共划分菱镁矿成矿区带11个。
The Ministry of Land and Resources in order to make out the nationwide important mineral resources,which provide the basis for mineral resources protection ability and exploration deployment decisions,to carry out the important mineral resources potential evaluation project.Magnesite is one of the25 important minerals to be carried out.The implementation of this project is an important national condition survey of mineral resources in China.In this work,we investigated the regional metallogenic pattern of magnesite through geological,geophysical,geochemical,remote sensing and mineralogical researches to establish a typical mineral deposit prediction model and a regional prediction model.Metallogenic prospect and target areas were identified,and the metallogenic resource potential of each prospecting area was assessed by modern theoretical analyses of mineral resource prediction and evaluation and GIS technology.The amount of 2000-meter subsurface shallow magnesite resources was estimated by means of geological volume and multivariate methods to provided a scientific basis for the rational planning and deployment of mineral exploration.Our study showed that the main metallogenic age of Chinese magnesite is Paleoproterozoic,and the metallogenic type is mainly sedimentary metamorphic type.A total of 36.42 million tons of magnesite resources were discovered largely in Liaoning,Shandong and Xinjiang provinces.In total,129 minimum magnesite prediction areas were identified,with 2000-meter shallow ore reserves amounted to 13.1 billion tons.Nationwide there are 11 typical magnesite ore deposit zones.
