However, according to the zircon U-Pb concordia age of plagiogranite porphyry in the Chihu porphyry molybdenum-copper district, recently some researchers believe that the mineralized plagiogranite porphyry was emplaced during the Late Carboniferous and that the mineralization is related to calc-alkaline magmatic intrusion in the Late Carboniferous convergence stage on the southern active margin of the Kazakhstan-Junggar plate.
东天山赤湖斑岩钼铜矿床的形成时代和成矿地质背景至今尚存在争议，前人根据同一成矿带中土屋-延东斑岩铜矿的同位素地质年龄信息，认为赤湖钼矿的形成时代为中—晚泥盆世，系塔里木板块北部活动陆缘泥盆纪岛弧火山-深成作用的产物；近期一些研究者根据赤湖斑岩钼铜矿区斜长花岗斑岩锆石U-Pb和谐曲线年龄，认为矿化斜长花岗斑岩的侵位时代为晚石炭世，成矿作用与哈萨克斯坦-准噶尔板块南部活动陆缘晚石炭世汇聚阶段钙碱性岩浆侵入作用有关。
Corresponding to these two deformation styles, two ore-forming system are developed in the studied area. One is late-collision porphyry ore-forming system(40.86±0.85Ma in age of Re-Os), which is controlled by strike-slip faults, produced the Narigongma porphyry molybdenum-copper deposits and the ages of porphyry intrusions and mineralization ages become increasingly young from the north to the south in Sanjiang area. The other is hydrothermal ore-forming system which is controlled by thrust faults system and produced Dongmozhazhua and Mohailaheng lead-zinc deposits. These two deposits occurs in the front thrust zone of the thrust faults system at 35.03±0.89 Ma and 34.0±1.1Ma(in age of Rb-Sr) respectively and their orebodies are formed in fracture zones or back thrust areas in the upper or lower plate of the imbricate thrust faults.
对应于两种构造变形样式，研究区形成两套成矿系统，即晚碰撞阶段走滑断裂控制的斑岩成矿系统和逆冲推覆构造控制的热液成矿系统，前者形成纳日贡玛斑岩型钼铜矿床，其成矿年龄为40.86±0.85Ma，并呈现出整个三江地区由北向南斑岩侵位年龄和成矿年龄逐渐变新的趋势；逆冲推覆构造控制的热液成矿系统形成东莫扎抓和莫海拉亨铅锌矿床，矿床形成于逆冲推覆构造的前锋带内，矿体多产在叠瓦状逆冲断层的上盘破碎带或反冲断层附近，成矿年龄为35.03±0.89Ma和34.0±1.1MaRb-Sr法

Results show that Pb enrichment factors varied from 1.0～1.8 in the cultural layers, and were not quite high. However, with the history going on from the Dawenkou Culture to the Longshan Culture, the Pb enrichment factor displayed an obvious rising trend, which indicated that the Pb in the cultural layers was probably associated with the development of metallurgic activities in the middle stage of the primitive society. From 5050 cal a BP to 4000 cal a BP, China underwent Stone Age, Chalcolithic Age and Bronze Age in sequence. Pb dust in the atmosphere increased with intensifying utilization of copper resources, which was probably the main cause of the rising enrichment factor in the cultural layers.
但是随着时间的推移，从大汶口文化到龙山文化，Pb的富集系数有明显逐步上升的趋势，表明遗址剖面中的Pb很可能与原始社会中期发展起来的冶金活动有关。5 050～4 000 cal a BP间，中国先后经历了石器时代、铜石并用时代，到最后进入青铜时代，这个过程中铜资源利用越来越多导致产生的大气粉尘铅越来越多，很可能是YC1剖面中Pb富集系数逐步增长的主要原因。
