| 中文摘要: |
| 宁夏青龙山石湾沟南冶镁白云岩矿床(矿石资源量3973.6万t)位于宁夏吴忠市青龙山东道梁南段,在该地区出露南北向数十千米中元古界蓟县系王全口组,岩性以灰色中厚层白云岩为主,其层位稳定,冶镁白云岩矿层厚度大,质量好,是硅热法及半连续硅热法炼镁的优质原料。本文结合前期地质勘查结果,根据矿体特征、产状及规模、矿石矿物成分、结构构造、矿石自然类型及成因分析,认为该矿床属稳定的化学沉积环境中形成的台地相碳酸盐岩沉积类型矿床。该研究为石湾沟南冶镁白云岩矿的后续勘查开发提供借鉴。 |
| 英文摘要: |
| Ningxia Qinglongshan Shiwangou south metallurgical magnesium dolomite deposit locates in southern part of east ridge, Qinglongshan mountain in wuzhong city of Ningxia . The Wangquankou formation of Mesoproterozoic Jixian system is exposed at northward and southward tens of kilometers in the area, lithology is mainly with gray medium bed dolomite, which is kind of quality raw material for magnesium smelting for ferrosilicon process and semicontinuous ferrosilicon process as for its stable horizon, massive thickness and good quality of smelting magnesium dolomite. Based on scientific and effective means and methods on geological work during the preliminary geological exploration project, In this thesis, based on the analysis on geological characteristics of ore body, occurrence and scale, mineral composition, structure and construction, natural type and genesis of the ore, the authors considered that the deposit mentioned above belongs to platform carbonate sedimentary type deposit which is formed in a stable chemical sedimentary environment. This study provides reference for the follow-up exploration and development of the metallurgical Magnesium dolomite deposit in Shiwangou South. |
