摘要
巴拉大才钨锡矿点位于青海省格尔木市以南约160 km处;构造上位于甘德-玛多断裂与昆南断裂之间,木孜塔格-布青山混杂岩与玛多-玛沁增生楔结合部位;区内地质条件良好,找矿潜力较大;笔者通过对巴拉大才钨锡矿点进行野外地质调查及手标本、光薄片进行详细观察与鉴定,查明了区内主要矿化体特征、矿石成分,并通过对比国内及区内白干湖钨锡矿田,总结了巴拉大才钨锡矿点主要控矿因素和找矿标志,初步认为该矿点为受岩浆与构造活动控制的中高温石英脉-云英岩型钨锡矿点(床)。
Baladacai tungsten-tin deposit is located at about 160km south of Golmud city, Qinghai province. It is tectonically in the binding site of Muzitage-Buqingshan melange betl and Maduo-Maqin accretionary wedge, between Gande-Maduo fracture and south Kunlun fracture. The geological condition and prospecting potential in this area are favorable. The main mineralization characteristics and mineral composition of Baladacai tungsten-tin deposit are clear and definite by the field geological survey and the detailed observation of hand specimens, the main ore-controlling factors and prospecting marks are summarized by comparing the domestic tungsten-tin deposits and Baiganhu tungsten-tin ore field. It is preliminary considered to be the high temperature quartz vein - greisen type tungsten-tin deposit controlled by magmatic and tectonic activities.
