In Central and Western Anatolia two continent-derived massifs simultaneously underthrusted an oceanic lithosphere in the Cretaceous ended up with very contrasting metamorphic grades: high pressure, low temperature Tavşanlı zone Kırşehir Block. To assess why, we reconstruct paleogeography plate configuration of using structural, metamorphic, geochronological constraints Africa-Europe reconstructions. We review provide new 40Ar/39Ar U/Pb ages from Anatolian magmatic rocks ophiolites show...
Apparent polar wander paths (APWPs) calculated from paleomagnetic data describe the motion of tectonic plates relative to Earth's rotation axis through geological time, providing a quantitative paleogeographic framework for studying evolution interior, surface, and atmosphere. Previous APWPs were typically collections poles, with each pole computed sites, site representing spot reading field. It was recently shown that choice how sites are distributed over poles strongly determines...
Based on the marine magnetic anomalies identified in Argo Abyssal Plain offshore northwestern Australia, conceptual continent of Argoland must have rifted off Late Jurassic (∼155 Ma) and drifted northward towards SE Asia. Intriguingly, Asia there are no intact relics a major such as India, but instead region displays an intensely deformed, long-lived accretionary orogen that formed during more than 100 million years oceanic continental subduction. Within this orogen, fragments may represent...
SE Asia comprises a heterogeneous assemblage of fragments derived from Cathaysia (Eurasia) in the north and Gondwana south, separated by suture zones representing closed former ocean basins. The western part region Sundaland, which was formed Late Permian-Triassic amalgamation continental arc now found Indochina, Thai Penisula, Peninsular Malaysia, Sumatra. On Borneo, Kuching Zone eastern margin Sundaland since Triassic. To Zone, Gondwana-derived SW Borneo East Kalimantan accreted...
Abstract Subduction polarity reversal during arc‐continent collision has been proposed as a key mechanism to initiate new subduction zones. Despite often interpreted, well‐exposed geological record that document the is sparse. The ophiolitic lithounits of Andaman and Nicobar Islands have formed initiation zone following Woyla Arc Sumatra with Sundaland (Eurasia). We here present field, petrological geochronological data evaluate timing subduction. targeted previously inferred but unstudied...
SE Asia exposes an intensely deformed, long-lived accretionary orogen that hosts accreted fragments of oceanic and continental crust, such as the Sula Spur Argoland were derived from Pangea-Tethys realm Proto-South China Sea was Panthalassa realm. The geologic record in provides incomplete remains subducted lithosphere forms basis for reconstructing lost tectonic plates paleogeography. Reconstructing these their paleogeography is challenging, often leads to widely different reconstructions,...
Reconstructing paleogeography from accretionary records is challenging due to the difficulty of integrating data sources different specialized fields. Here, we present ‘orogenic architecture diagram’ method systematically compile geological in temporal and spatial context at scale nappes - ‘building blocks’ orogens use their interpreted histories as a base for tectonic paleogeographic reconstruction. We identify lower plate-derived Continental or Ocean Plate Stratigraphy, upper ophiolites...
The configuration and evolution of subduction zones in the Eastern Mediterranean region Cretaceous time accommodating Africa–Europe convergence remain poorly quantitatively reconstructed, owing to a lack kinematic constraints. A recent palaeomagnetic study suggested that triangular Central Anatolian Crystalline Complex (CACC) consists three blocks once formed an ~N–S elongated continental body, underthrusted below ophiolites Late time. After extensional exhumation upon Palaeogene collision...
Abstract The Sibumasu Block in SE Asia represents the eastward continuation of Qiangtang Block. Here we report a detailed rock magnetic and paleomagnetic study on Middle Jurassic Paleocene rocks from northern Sibumasu, to document crustal deformation during India‐Asia collision since reconstruct overall strike Qiangtang/Sibumasu elements before collision. Although fold test is inconclusive based solely our data, positive reversal test, regional with previous results, detrital origin hematite...
Abstract The dynamics of slab detachment and associated geological fingerprints have been inferred from various numerical analog models. These invariably use a setup with slab‐pull‐driven convergence in which detaches below mantle‐stationary trench after the arrest plate due to arrival continental lithosphere. In contrast, reconstructions show that post‐detachment is common trenches sutures are rarely during detachment. Here, we identify more realistic kinematic context using example...

The Andaman and Nicobar ophiolites, in the forearc of western Sunda subduction zone, underwent enigmatic, rapid Cenozoic vertical motions: shallow-water sediments with abundant arc debris characterize middle Paleocene–middle Eocene are under- overlain by significantly deeper sediments. Recent paleomagnetic results revealed a near-equatorial paleolatitude West Burma Block associated at similar latitude as until early Eocene, providing new avenue toward explaining unusual stratigraphy. Here,...
The South China, Indochina, and Borneo margins surrounding the China Sea contain long-lived arcs that became inactive at approximately 85 Ma, even though an embayment of oceanic crust (the ‘Proto-South Sea’) remained in intervening region. This eventually subducted Cenozoic below Cagayan arc, while modern opened its wake. To investigate enigmatic cessation Mesozoic subduction Borneo, we studied a fragment overlyinƒg trench-fill sediments accreted to NW during final stages subduction. Based...

Can continents get lost? The geological textbooks predict that when enter subduction zones, either stops, or part of the crust is scraped off and preserved in orogens. A possible exception has been conceptual continent Argoland. Argoland must have broken NW Australian margin Late Jurassic migrated north to end up somewhere SE Asia, but previously identified fragments may form candidates are too small represent all Argoland, geology shows they were once separated by oceanic basins much older...
