| 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)。

Discussion on Geological Features and Genesis of Baladacai Tungsten-tin Deposit in Qinghai Province |
| |
| Abstract: | Baladacai tungsten?tin deposit is located at about 160km south of Golmud city, Qinghai province. It is tectonical?ly 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 consid?ered to be the high temperature quartz vein?greisen type tungsten?tin deposit controlled by magmatic and tectonic activities. |
