青藏高原及其周边地区具有漫长且复杂的构造演化历史.印度北部、拉萨、羌塘、柴达木、中祁连等大小不同的克拉通和地块,以及位于它们之间的造山带构成了青藏高原的主体.寒武纪时期,这些克拉通和地块大多位于冈瓦纳大陆的西北缘,并以发育与原特提斯洋有关的复杂岩浆-构造运动而与周边的阿拉伯、中伊朗、阿富汗、塔里木、阿拉善、华北、华南和滇缅马等构造单元相关联.从地层记录上看,这一时期区域内的大部分稳定陆块上发育了由陆源碎屑岩和碳酸盐岩组成的浅水陆棚沉积,其中包含面貌相近的典型浅水相三叶虫组合.而在原特提斯洋中的祁连构造带,寒武系则是一套在大洋扩张环境下形成的、以中基性火山岩和硅质岩为主的复杂地层序列,其中包含的碳酸盐岩含有斜坡相三叶虫组合.本文在广泛文献调研的基础上,结合第二次青藏高原综合科学考察中的野外观察及新获得的化石证据,对青藏高原及其周边地区不同构造单元上寒武纪地层发育的总体特征进行了概述.在此基础上,利用可获得的生物地层学和同位素年代学等资料,总结了不同构造单元上寒武纪地层的划分和年代地层对比,编制了岩石和生物地层的综合对比表.此外,从生物古地理的角度,简要讨论了寒武纪研究区内主要构造单元的古地理相关性,以及与原特提斯构造带演变有关的问题.

青藏高原及其周边的块体,包括印度板块、拉萨地块、羌塘地块、塔里木板块、欧龙布鲁克地块、中祁连地块、阿拉善地块、华北板块、扬子板块、中伊朗地块和阿曼等,以及各块体之间造山带的复杂演化历史是地球科学研究的前沿和热点.成冰系和埃迪卡拉系广泛分布于该地区的各个构造单元,其中阿曼、印度板块、扬子板块以及塔里木板块发育有相对完整的成冰系和埃迪卡拉系;而在中伊朗地块、南羌塘地块、中祁连地块、阿拉善地块及华北板块,目前已知仅有埃迪卡拉系发育.基于前人对青藏高原及其周边地区成冰系和埃迪卡拉系的研究,结合第二次青藏高原综合科学考察研究项目开展以来获得的新资料和研究进展,本文建立了该地区成冰系和埃迪卡拉系代表性地层序列对比表.在此基础上,本文梳理了该地区这一时期生物群和重大地质事件的研究现状和存在的问题.结果表明,该地区各板块埃迪卡拉纪化石的保存和组合面貌各具特色,但普遍发现有典型埃迪卡拉纪末期化石分子Cloudina和Shaanxilithes;除成冰纪两次全球性冰期事件外,在青藏高原北缘各块体(华北板块、阿拉善地块、北祁连构造带、中祁连地块、欧龙布鲁克地块、塔里木板块)以及伊朗中南部普遍记录了一次埃迪卡拉纪晚期的冰川事件,但该事件的时限、分布范围和成因有待进一步揭示;同时,埃迪卡拉纪中期DOUNCE/Shruam碳同位素负异常事件在青藏高原周边地区也具有广泛记录.综合现有研究资料发现,在成冰纪-埃迪卡拉纪期间,青藏高原及其周边地区大多数块体从罗迪尼亚超大陆裂解出来后,可能通过泛非运动构成东冈瓦纳大陆的一部分,而部分板块(如华北板块)位于冈瓦纳大陆和劳伦大陆之间.总体而言,该地区的主要块体在成冰纪-埃迪卡拉纪期间具体的古地理演化模型存在较多争议,亟需开展进一步的研究工作.

magnesium and aluminum alloys continually attract interest as lightweight structural materials for transport applications. However, joining these dissimilar alloys is very challenging. The main obstacle that hinders progress in dissimilar mg-Al joining is the formation of brittle intermetallic compounds(ImCs). As a solid-state joining technique, FSW is an excellent candidate to attenuate the deleterious ImC effects in dissimilar Al-mg joining due to the inherent low heat inputs involved in the process. However, the ImCs, namely Al_(3)mg_(2) and Al_(12)mg_(17) phases, have also been reported to form during Al-mg dissimilar FSW;their amount and thickness depend on the heat input involved;thus,the weld parameters used. Since the heat dissipated in the material during the welding process significantly affects the amount of ImCs,the heat input during FSW should be kept as low as possible to control and reduce the amount of ImCs. This review aims to critically discuss and evaluate the studies conducted in the dissimilar Al/mg FSW through a scientometric analysis and also with a focus on the strategies recently applied to enhance joint quality. The scientometric analysis showed that the main research directions in mg/Al FSW are the technological weldability of aluminum and magnesium during FSW, structural morphology, and mechanical properties of dissimilar welded joints. Considering the scope of application of the aforementioned joints, the low share of articles dealing with environmental degradation and operational cracking is surprising. This might be attributed to the need for well-developed strategies for obtaining high-quality and sustainable joints for applications. Thus, the second part of this review is conventional, focusing mainly on the new strategies for obtaining high-quality mg/Al joints. It can be concluded that in addition to the necessity to optimum welding parameters to suppress the excessive heat to limit the amount and thickness of ImC formed and improv
