Geochemical and isotopic data for metabasic rocks in NW Yunnan constrain the nature of the mantle source beneath the East Himalayan syntaxis during Neotethyan subduction and the timing of initial collision between India and Asia. Our results indicate that these mafic rocks crystallized at 50-55 Ma and were metamorphosed at 9 Ma, contemporaneous with magmatic flare-ups and high-grade metamorphism in South Tibet. The mafic rocks in NW Yunnan are divisible into three groups. Group 1, from Nabang, shows geochemical affinity to a MORB-like source modified by the recycled component with εNd(t) of +5.1 to +9.5 and εHf(t) of +5.1 to +11.6, and resembles back-arc basin basalt. Group 2 is mainly from Jinzhouzhai and Tongbiguan to the east of Group 1, and is marked by high Al2O3, enrichment in LILEs and depletion in HFSEs, along with negative εNd(t) values(–1.1 to –5.6) and εHf(t)(-4.6 to-0.9). Group 2 is interpreted to have originated from the lithospheric mantle modified by input from a slab-derived component in a continental arc setting. Group 3, from Nanjingli, is located a considerable distance east from Group 1, and exhibits negative εNd(t)(–6.7 to –7.6) and εHf(t)(-7.1 to-2.2), and is inferred to be derived from the Tengchong lithospheric mantle but with limited involvement of a slab-derived component. Overall Nd-Hf isotopic compositions show a sharp decrease from Group 1 to Group 2 and then a more subdued decrease to Group 3, with the three groups corresponding to an overall spatial distribution from west to east. Our results suggest that early Eocene magmatism in NW Yunnan represents the eastward continuation of the Gangdese magmatic belt and that Neotethyan subduction continued until 0 Ma followed by India–Asia collision. At least two eastward subduction zones are involved in the Neotethyan suprasubduction system prior to 55 Ma. The sudden decrease in convergence rate in the early Eocene(55-50 Ma), together with the inferred positive buoyancy of the Tengchong lithosp

Acta Geologica Sinica(English Edition) 2020年第S01期94卷 8-8页

The Makran represents a huge accretionary wedge in SE Iran that resulted from the long-lasting subduction of the Neotethys Ocean since the Mesozoic. From west to east, this accretionary wedge extends ~1000 km between the Minab Fault in Iran, and the Ornach-Nal Fault in Pakistan. The ongoing oceanic subduction characterizes this belt between the Iranian Plateau and the Tibetan Plateau, both of which were generated by collision of Eurasian with the Arabian and Indian plates, and provides an ideal target to recover the tectonic history of subduction. The western Makran located in Iran can be subdivided into four units: The North Makran ophiolitic mélange, the Inner Makran, the Outer Makran, and the Coastal Makran. Based on our detailed structural analysis and geochronological dating, we obtain several new results that can help us to better understand the structural evolution:(1) The North Makran ophiolitic mélange includes thick piles of volcanic rocks and limestone that directly cover the mantle peridotite, so it is likely to be part of an Early Cretaceous volcanic arc by our zircon dating at ~115 Ma on mafic intrusions;(2) The entire western Makran underwent three phases of deformation. D1 is characterized by top-to-the S/SW thrusting as evidence by southward emplacement of the ophiolitic mélange onto the Eocene sedimentary rocks. D2 deformation strongly folded the pre-late Miocene/early Pliocene strata that also corresponds to the final emplacement of the ophiolite to the surface. D3 structures extends in a N-S direction with top-to-the W kinematics that overthrust the Miocene sandstone onto the Pliocene fluvial sediments along the Minab Fault;(3) Combined with geological and geochronological relationship, D1 occurred at ~45-35 Ma, D2 initiated in middle Miocene and ended with a regional late Miocene-early Pliocene uncomformity, and D3 structures are still active as the subduction continues.

为了满足不同的技术和经济目标,从轻度混合动力、插电式混合动力到全电池动力的电动汽车,都将依赖于新型的、先进的(如基于锂的)蓄电池。这些电池在各种应用条件下的性能预测和寿命表征费工、费时,目前尚未得到充分的发展。一些国家已投入资金和人力进行相关的研究,其实通过国际合作,这些努力和花费也许能发挥更大的作用,例如目前正在国际能源机构(The International Energy Agency,IEA)框架内开展的准备工作。正在致力于开发一套标准化的、加速的测试程序,将允许各个测试机构合作分析电池的测量数据。该文评述了欧洲、日本和美国在加速寿命测试程序上的最新进展。以国际合作为目标,搜集、对比和分析现有的测试程序。

拟建中巴铁路是我国"一带一路"倡议中南下通道的重要组成部分。中巴铁路廊道位于喜马拉雅、喀喇昆仑、兴都库什三大山系的交汇区,裂点分布密集,类型齐全。为了增强对裂点地貌效应的认识并合理利用,以中巴经济走廊红其拉普—塔科特段为研究区,首先基于铁路选线对地貌观测尺度的需求,提出了裂点规模的判据并建立了不同类型裂点的判识方法;然后通过对裂点上下游山地灾害数量的对比,证实了裂点上游河段更稳定的规律;最后基于不同类型裂点河流地貌演变效应的分析,提出构造型裂点上游的河流相基座阶地、滑坡型裂点形成的淤积地貌均为铁路布线的良好地形,对于冰川型裂点形成的开阔地形,须确认属小冰期冰川未到达的区域方可利用。

中巴经济走廊是我国"一带一路"倡议的先试区和重点项目区,拟建中巴铁路是其重要组成部分。走廊区域经历了多次强隆升作用和冰川作用,存在河流阶地、洪积扇、泥石流扇、冰碛台地等沿河台地。以中巴经济走廊Thakot至Khunjerab段为研究区段,归纳总结各类沿河台地的分布特征以及铁路选线的可利用性。结果表明:由于强隆升作用导致河流阶地拔河高度较大并出现了泥石流扇抬升后成为流通区的现象,Ⅰ级阶地和老扇面区成为可利用的地形;小冰期时冰川活动未企及的冰碛台地也可利用。研究结果有益于中巴铁路线路方案的优化。
