Incremental accretion of continental fragments from East Gondwana to Eurasia resulted in the growth of Asia and rise of the Tibetan Plateau, yet its detailed evolution remains uncertain. Argoland, a continental fragment that rifted from NW Australia during the Late Jurassic, played a key role in the initial opening of the Indian Ocean and the evolution of eastern Tethys. However, its present identity remains elusive, with East Java-West Sulawesi currently assumed to be the most likely option. To constrain the missing Argoland and its role in India-Asia convergence, we report new detrital zircon data from Sulawesi, Indonesia, and West Burma, Myanmar, and synthesize literature results from relevant regions in Southeast Asia, which (>15,000) reveal age profiles of West Sulawesi, the central Sulawesi metamorphic belt, and southeast Borneo comparable to that of Bird’s Head, New Guinea, whereas age patterns of West Burma and East/West Java are similar to those of NW Australia. Notably, the most dominant age populations in NW Australia are rarely detected in Sulawesi and Borneo. These observations, combined with previous geological records and recent paleomagnetic data, suggest that West Burma is the mysterious Argoland, opposing the currently favored East Java-West Sulawesi model, with East Java and West Sulawesi probably having originated from NW Australia and Bird’s Head, respectively. We estimate an average northward motion of ∼6−8 cm/yr for West Burma, which split from NW Australia to approach the equator during ca. 155−95 Ma, shedding new light on the reconstruction and breakup of northern East Gondwana, progressive building of Southeast Asia, and India-Asia convergence.

AbstractThe Zhongwunongshan Structural Belt (ZWSB) locates between the Olongbruk Microblock of North Qaidam and the South Qilian Block in China, and it has important implication for understanding the tectonic significance of North Qaidam. Nowadays, there are few discussion on the Caledonian tectonothermal events of the Zhongwunongshan Structural Belt, and there exist different opinions on provenance and tectonic environment of the Zhongwunongshan Group in the ZWSB and its adjacent North Qaidam. In this study, a comprehensive analysis of the detrital zircon geochronological research was carried out on the Zhongwunongshan Group. The detrital zircon U-Pb dating results showed two major populations. The first was Neoproterozoic (966-725 Ma) with a ∈Hf(t) = −15.9 to 9.5, and the other was late Early Paleozoic (460-434Ma) with a ∈Hf(t) = −9.6 to −3.1. In combination with previous research, the dominated provenances were found to be the Neoproterozoic granitic gneiss of the Yuqia-Shaliuhe HP-UHP metamorphic belt and the late Early Paleozoic granite of the Tanjianshan ophiolite-volcanic arc belt in North Qaidam. The Zhongwunongshan Group was deposited in the back-arc sedimentary basin related to the Caledonian collisional orogeny during Middle Silurian-Early Devonian (434-407.9 Ma).

Ships sailing from Fujian to Southeast Asia could choose between two different sea routes. The first route followed the China coast to central Guangdong; it then led to Hainan, the Champa coast and Pulau Condore, an island near the southern tip of Vietnam. From there it continued in three directions: to Siam, to northwestern Borneo and to the Malayan east coast. Going south to the Malayan east coast was the most direct way to Trengganu, Pahang, Pulau Tioman, Johore and modern Singapore whence it was possible to sail into the Indian Ocean or to cross over to Sumatra, Bangka Island and Java.

AbstractThe Shuhi of Muli County, Sichuan Province, are one of multiple ethnic groups inhabiting the river gorges of the Qinghai-Gansu-Sichuan corridor between the Tibetan plateau and the Chinese lowlands. The Shuhi have grown paddy rice since times immemorial at an unusually high altitude (ca. 2,300 m above sea level). This article aims to explain this conundrum not merely through the ecology (as is common among Tibetan area specialists), but by researching the cultivation and consumption of rice as a historically-evolved cultural practice. According to a recently formulated agro-archaeological hypothesis regarding the macro-region of Eurasia, it is possible to identify two supra-regional culture complexes distinguished by their respective culinary technologies: rice-boiling versus wheat-grinding-and-baking. The hypothesis posits that the fault line between the two supra-regional cultural complexes is precisely along this river gorges corridor. In this article we provide support for this hypothesis arguing that Shuhi ritual and kinship practices have much affinity with those of other rice-boiling peoples in Southeast Asia, whereas certain of their current religious practices are shared with the wheat-grinding Tibetans.

Studies of the archipelago (nusantara) on the notes of foreign travelers written in the 9th and 10th of centuries are still quite rare.  Indeed, there have been several studies on the notes of travelers such as Ma Huan (China), Tome Pires (Portuguese), Ibn Bathuthah (Arabic), and some others. But, these studies revolve around the notes of travelers after the 10th of century.  Meanwhile, notes of travelers who came to the archipelago (nusantara) in the century before 10 AD have not got serious attention yet. This book is a travel note's report which captures various activities in India, China and Southeast Asia. This book also contains a history about how Islam met in the Sarandib area.  There are many interpretations of sarandib accurate location today. The findings of Keram Kevonian in his research on the names of regions in the Indian Ocean region using Armenian language sources stated that Sarandib means Swarnadipa which was no other than Sumatra.

This introductory chapter flips the more common historical perspective that European imperialism led to new patterns of legal pluralism across empires that spawned possibilities for interpolity contact and trade, acting as catalysts for the emergence of global legal regimes. It demonstrates how British and Dutch territorial jurisdictions expressed very specific relationships between territory, authority, and forms of law, and it simultaneously puts into stark relief the preponderance of diasporic Arab merchants generating their own jurisdictions across the Indian Ocean in tandem with those of the European colonist. Not only were these Arabs attuned to legal pluralism being the operative condition of law, they were also acutely aware of jurisdictional ordering and the concentration of power across time and space. The chapter proposes a spatial repositioning of the Indian Ocean from the perspective of Southeast Asia outward toward Hadramawt, a region located in present-day Yemen from which most Arabs in Southeast Asia originated. Ultimately, it presents the result of the legislation after members of the Hadhrami diaspora attempted to bring their own regulation with them, inscribing territorial lines across the Indian Ocean through law.

Abstract The Yangtze Block in South China constitutes an important Precambrian landmass in the present East Asian continent. The Neoproterozoic sedimentary successions of the Hengdan Group in the NW Yangtze Block record essential information for deciphering the Neoproterozoic tectonics along the NW margin. However, its depositional age, provenance and tectonic properties remain uncertain. Here, a combined analysis of detrital zircon U–Pb dating and geochemistry is performed on representative samples from the Hengdan Group. Concordant dating results of samples from the bottom and upper parts constrain the maximum depositional age at c. 720 Ma. Detrital zircon age patterns of samples reveal a uniformly pronounced age peak at c. 915–720 Ma, which is consistent with the magmatic pulses in domains at the NW end of the Yangtze Block. In addition, these samples display left-sloping post-Archaean Australian shale (PAAS)-normalized rare-earth element patterns and variable trace element patterns, resembling sediments accumulated in a basin related to an active continental margin geodynamic setting. Provenance analysis reveals that the main sources featured intermediate to felsic components, which experienced rapid erosion and sedimentation. These integrated new investigations, along with previous compilations, indicate that the Hengdan Group might have been deposited in a fore-arc basin controlled by subduction beneath the Bikou Terrane. Thus, such interpretation further supports proposals for subduction-related tectonics along the western margin of the Yangtze Block during the early Neoproterozoic.

Abstract The Tibetan Plateau (TP) and Himalayas have been treated as an essential external factor in shaping Asian monsoon and mid-latitude atmospheric circulation. In this study we perform numerical experiments with different uplift altitudes using the Nanjing University of Information Science and Technology Earth System Model to examine potential impacts of uplift of the TP and Himalayas on eastward propagation of the MJO and the associated mechanisms. Analysis of experimental results with dynamics-based MJO diagnostics indicates two potential mechanisms. First, the uplift considerably enhances low-level mean westerlies in the Indian Ocean and convection in the Maritime Continent, which in turn strengthens boundary layer moisture convergence (BLMC) to the east of the MJO convective center. The increased BLMC reinforces upward transport of moisture and heat from BL to free atmosphere and increases lower tropospheric diabatic heating by shallow and congestus clouds ahead of the MJO center, enhancing the Kelvin-Rossby wave feedback. Second, the uplift increases upper tropospheric mean easterlies and stratiform heating at the west of the MJO center, which contributes to eastward propagation of MJO by generating positive moist static energy at the east of MJO center. This study will contribute to a better understanding of the origin of the MJO and improvement in simulation of MJO propagation.
