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.

在东特提斯群岛追踪 Argoland 及其对印度-亚洲融合的影响

从东冈瓦纳到欧亚大陆的大陆碎片的增量增加导致了亚洲的增长和青藏高原的隆起，但其详细演变仍不确定。Argoland 是侏罗纪晚期从澳大利亚西北部裂开的大陆碎片，在印度洋的最初开放和东特提斯的演化中发挥了关键作用。然而，它目前的身份仍然难以捉摸，东爪哇-西苏拉威西目前被认为是最有可能的选择。为了限制缺失的 Argoland 及其在印度-亚洲融合中的作用，我们报告了来自印度尼西亚苏拉威西岛和缅甸西部缅甸的新碎屑锆石数据，并综合了东南亚相关地区的文献结果，其中（> 15,000）揭示了年龄分布西苏拉威西，中苏拉威西变质带，和东南婆罗洲与新几内亚的鸟头相媲美，而西缅甸和东/西爪哇的年龄模式与澳大利亚西北部相似。值得注意的是，在苏拉威西岛和婆罗洲很少发现澳大利亚西北部最主要的年龄人口。这些观察结果，结合以前的地质记录和最近的古地磁数据，表明西缅甸是神秘的阿尔戈兰，与目前流行的东爪哇-西苏拉威西模型相反，东爪哇和西苏拉威西可能分别起源于澳大利亚西北部和鸟头. 我们估计西缅甸的平均向北运动约为 6-8 厘米/年，大约在 20 年左右从澳大利亚西北部分裂到接近赤道。155-95 Ma，揭示了东冈瓦纳北部的重建和分裂，东南亚的进步建设，
