2019年,西北大学与青海省文物考古研究所联合对青海省都兰县夏尔雅玛可布遗址进行考古调查,重点记录了石墙、土坯墙、墓葬等遗迹现象,采集到陶片、石制品等遗物,明确了该遗址是一处由居址区和墓葬区组成的大规模诺木洪文化聚落,并发现... 详细信息

2019年,西北大学与青海省文物考古研究所联合对青海省都兰县夏尔雅玛可布遗址进行考古调查,重点记录了石墙、土坯墙、墓葬等遗迹现象,采集到陶片、石制品等遗物,明确了该遗址是一处由居址区和墓葬区组成的大规模诺木洪文化聚落,并发现居址区防御体系是由双重或三重石墙构成。碳十四测年结果显示该遗址距今3400~3000年。作为目前规模最大、功能齐全的诺木洪文化遗址,对夏尔雅玛可布的进一步研究将为揭示诺木洪文化内涵、探索青铜时代青藏高原东北缘与周邻地区的人群交往和文化融合等议题提供重要资料。

The Salobo 3A polymetallic Cu (Au-Mo-Ag) deposit, located in the southeastern part of the Amazonian Cra- ton, northern Brazil, is hosted by an Archean metavol- cano-sedimentary sequence of Salobo Group. The cop- per mineralization consists of bornite-chalcocite and bornite-chalcopyrite disseminated with magnetite. In this paper we attempt to date the mineralization episodes and to characterize the uid sources. The step- wise Pb leaching technique applied to chalcocite, tour- maline, chalcopyrite and magnetite yielded 207 Pb-206Pb ages of 2705 42 Ma, 2587 150 Ma, 2427 130 Ma, and 2112 12 Ma, respectively. The older age is inter- preted as the timing of primary mineralization. Ages of 2.58 Ga and 2.42 Ga are considered to be related to tec- tonic reactivation of the Itacai nas belt, and the younger age, obtained on late magnetite crystals, sug- gests the presence of Paleoproterozoic hydrothermal episode. Sm-Nd and Rb-Sr ages of 2.4 and 2.1 Ga were obtained for schists from the Salobo Group and chlori- tized gneisses of the Xing Complex, respectively. The strong radiogenic Pb isotopic compositions of all analyzed minerals suggest a continental environment for the mineralizations. Our geochronological results are in agreement with a primary syngenetic origin for the Salobo miner- alization, with late remobilization into brittle-ductile structures during a policyclic evolution of the Caraj s- Cinzento strike-slip system. Low-grade metamorphism and anorogenic granitic plutonism affected the area at ca. 2.1 and 1.8 Ga, respectively.
