| 摘 要： | 西藏玉龙铜矿带以班岩铜矿带闻名于世，而对成矿带中最具工业价值的似层状氧化矿体的研究较少。在“国家计委'９５重大项目专题研究”的最新基础资料和研究成果基础上，我们首次提出了西藏东部上三叠统甲丕拉组的“沉积矿质初步富集”，并以玉龙铜矿床似层状矿体的解剖阐述它与玉龙铜矿带的关系。这对于在玉龙铜矿带进一步寻找同类型富矿提供了一个新的方向。

| Abstract: | The copper ore provenance effect by sedimentation of Jiapela Formation of Upper Triassic in the East Tibet is first put forward by the authors based on the latest data and research from srtatigraphy ,sedimentology, geochemistry of trace elements and rare earth elements ,and so on. And the relationship between the proveper ore was been principally affected by sedimentation in Late Triassic ,and its forming environment was anactive continental margin. The chondrite normalized pattern of REE from copper sandstones and mudstones of Jiapela Formation is different from the Yulong granite-porphyry in the content of REE and oblique type from the pattern. |
