Downgoing Plate‐Buoyancy Driven Retreat of North Sulawesi Trench: Transition of a Passive Margin Into a Subduction Zone

Geophysical Research Letters, 2022
The transition of a passive continental margin into a subduction zone remains a hypothesis because few geological cases have been reported. The North Sulawesi subduction zone is a 5–9 myr system in Southeast Asia that has evolved from a passive ...

Geochemical Evidence of Island-Arc Origin for Sumatra Island; A New Perspective based on Volcanic Rocks in Lampung Province, Indonesia

Indonesian Journal on Geoscience, 2014
DOI: 10.17014/ijog.v6i4.128Since decades, Sumatra Island is considered as the Eurasia continental margin where the Indian Ocean plate has been subducted oblique beneath the continental plate of Sumatra.

Petrogenesis and tectonic settings of epithermal mineralization-related granites in the Xinchenggou area, NE China

Frontiers in Earth Science, 2023
The Xinchenggou area is located in the northeast part of the eastern segment of the Xingmeng orogenic belt (EXOB), NE China and has been demonstrated to be a promising exploration target for epithermal deposits.

Hydrocarbon accumulation in the deep waters of South China Sea controlled by the tectonic cycles of marginal sea basins

Petroleum Research, 2016
: The tectonic cycle of the marginal sea basins in South China Sea (SCS) includes two cycles, i.e., the formation and contraction of Palaeo-SCS and Neo-SCS.

Sedimentation record in the Konkan-Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin [PDF]

, 2007
The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin.

Structural inversion in the northern South China Sea continental margin and its tectonic implications

Terrestrial, Atmospheric and Oceanic Sciences, 2017
The northern South China Sea (SCS) continental margin was proposed to be an active margin during the Mesozoic. However, only a few papers discussed the Mesozoic structural evolution in this region.

Lithospheric controls on melt production during continental breakup at slow rates of extension: Application to the North Atlantic

, 2009
Rifted margins form from extension and breakup of the continentallithosphere. If this extension is coeval with a region of hotter lithosphere,then it is generally assumed that a volcanic margin would follow.

Ongoing Inversion of a Passive Margin: Spatial Variability of Strain Markers Along the Algerian Margin and Basin (Mediterranean Sea) and Seismotectonic Implications

Frontiers in Earth Science, 2021
Subduction initiation is an important but still poorly documented process on Earth. Here, we document one of a few cases of ongoing transition between passive and active continental margins by identifying the geometrical and structural signatures that ...
