摘要
甘肃镁矿勘查工作程度低,已知的矿产地在甘肃储量平衡表中绝大多数是以菱镁矿和白云岩矿产地"入库"的,仅天水市毕家里、环县阴石峡、平凉市转马台白云岩矿是以炼镁白云岩"入库"。经确认有2处菱镁矿矿床和42处白云岩矿(点)床符合提炼金属镁的工业要求,并具有成矿条件优越、矿床类型单一、资源丰富、分布广、质量好、多用途的特点。综述了镁矿成矿的时空分布规律,并以甘肃Ⅳ级成矿亚带为主线,简述了成矿特征,探求了资源潜力。如能加大镁矿勘查投入力度,有望在甘肃实现找矿的重大突破。
The exploration level of magnesium mine is low in Gansu Province.Most of the known mineral lands in Gansu Reserve Balance Table are stored by as magnesia and dolomite mines,and only the dolomite mines of the Bijiali in Tianshui city,yinshixia in Huan County and Zhuanmatai have been stored in magnesiasmelting dolomite.It has been confirmed that 2 magnesite deposits and 42 dolomite deposits which it is characterized by superior metallogenic conditions,single deposit type,abundant resources,wide distribution,good quality and multi-purpose,meet the industrial requirements for the extraction of magnesium metal.This paper summarized the temporal and spatial distribution of magnesium mineralization,and takes the IV metallogenic subzone as the main line,briefly describes the metallogenic characteristics and explores the resource potential.If we can increasd the investment in magnesium exploration,it is hopeful to achieve a major breakthrough in prospecting in Gansu Province.
