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.

The seismic reflection Moho across the mid-Norwegian continental rifted margin

Communications Earth & Environment, 2022
The seismic reflection Moho at the Mid-Norwegian continental rifted margin can be imaged in the context of the lower crust and upper mantle across the whole margin using high resolution seismic reflection data.

Estimation of the gas hydrate saturation from multichannel seismic data on the western continental margin of the Chukchi Rise in the Arctic Ocean

Frontiers in Earth Science, 2022
A multichannel seismic survey was conducted to investigate the geophysical characteristics of gas hydrates along the western continental margin of the Chukchi Rise around an ARAON mound cluster, which was first recovered in 2016. In the seismic data, gas

Mechanical decoupling of high-pressure crustal units during continental subduction. [PDF]

, 2008
International audienceThe mechanics of the transition from continental subduction toward upper crustal nappe stacking is still poorly understood and is studied here through a 2D thermal and strength numerical modelling of a subducted passive margin ...

A leaf phenomics approach for estimating belowground traits in North American licorice

American Journal of Botany, EarlyView.
Abstract Premise Selective breeding over thousands of years has prioritized aboveground yield, with little regard for changes belowground. Roots underpin plant growth and resilience, but our knowledge of these critical structures lags behind that of aboveground structures.

Climate and seed mass drive intraspecific variation in seed longevity in storage

American Journal of Botany, EarlyView.
Abstract Premise Conservation seed banks are essential for ex situ plant conservation, but stored seeds slowly deteriorate and lose viability. Seed longevity in storage is determined by the initial seed viability and the rate of seed viability loss. The rate of seed viability loss in storage varies between species and possibly between populations or ...

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 ...

Structure of Continental Margins

Journal of geomagnetism and geoelectricity, 1970
The margins of the continents or transition zones between continents and oceans are divided traditionally into two types: Atlantic and Pacific. There are also some transition types between these two.From the geophysical point of view the border between a continent and an ocean is determined now as an area where changing the crust from continental type ...

Geochemical Signature of Mesozoic Volcanic and Granitic Rocks in Madina Regency Area, North Sumatra, Indonesia, and Its Tectonic Implication [PDF]

, 2009
Http://dx.doi.org/10.17014/ijog.vol4no2.20094Five samples consisting of two Permian-Triassic basalts, two Triassic-Jurassic granitic rocks, and a Miocene andesite were collected from the Madina Regency area in North Sumatra that is regionally situated on
