中文摘要:
      柴北缘地区大地构造位置处于古亚洲构造域与特提斯构造域结合部位的多旋回弧盆造山系,锂铍等稀有金属矿成矿地质条件优越。近年来,该地区锂铍矿找矿取得重要进展。本文通过论述柴达木盆地北缘锂多金属矿的成矿地质背景、典型矿床、成矿条件等特征,并据柴北缘地区化探异常及找矿标志等特征,认为龙尾沟、大柴旦北山、布赫特山、沙柳河、茶卡北山等地区为伟晶岩型稀有金属重点找矿区;柴北缘地区也将是青藏高原东北缘锂铍等稀有金属矿找矿潜力区之一。
英文摘要:
      The tectonic setting of the northern Qaidam Basin is a multi-cycle arc basin orogenic system located at the junction of Paleo-Asian tectonic domain and Tethys tectonic domain. Rare metal deposits such as lithium beryllium in the northern margin of Qaidam basin have favorable geological conditions for mineralization. In recent years, important progress has been made in prospecting for lithium beryllium in this area. Based on the discussion of the metallogenic geological background, typical deposits, metallogenic conditions and other characteristics of lithium polymetallic deposits in the northern margin of Qaidam basin, and according to the characteristics of geochemical anomalies and prospecting criteria in the northern margin of Qaidam basin, Through research, we believe that Longweigou, Dachaidan Beishan, Buchert Mountain, Shaliu River, Chaka Beishan and other areas are key pegmatite rare metal prospecting areas. The northern margin of Qaidam will also be one of the prospecting potential areas for rare metal deposits such as lithium beryllium in the northeastern margin of the Qinghai-Tibet Plateau.
