Sedimentary and tectonic evolution of Paleocene-Eocene chaotic facies from Western Ligurian Flysch (Italy) [PDF]

Swiss Journal of Geosciences
Chaotic deposits are common in convergent margins and are crucial for understanding subduction dynamics and basin evolution. This study re-evaluates key chaotic deposits within the Western Ligurian Flysch, focusing on the Colla Domenica Shales and the ...

Surficial sedimentary properties of Makran accretionary prism and its application to natural gas hydrate distribution

Frontiers in Marine Science
The Makran accretionary prism (MAP) resulted from the low-angle, slow-rate subduction of the Arabian Plate beneath the Eurasian Plate. The MAP is an active continental margin, with natural gas hydrate (NGH).

INTRA-OCEANIC ARCS OF THE PALEO-ASIAN OCEAN

Геодинамика и тектонофизика, 2017
Intra-oceanic arcs (IOAs) form at Pacific-type convergent margins, in the upper “stable” plate, when the subducting plate submerges to the depths of melting, i.e., to ca. 50–100 km.

Punctuated growth of an accretionary prism and the onset of a seismogenic megathrust in the Nankai Trough

Progress in Earth and Planetary Science, 2018
Ocean drilling in the Nankai Trough forearc suggests a new scenario for the evolution of the Nankai subduction zone. Continuous subduction since the Late Cretaceous has been a common tectonic scenario, although the plate subduction was transferred from ...

Origins of porosity and velocity variations at Cascadia Accretionary Prism [PDF]

Geophysical Research Letters, 1997
At Cascadia accretionary prism, log‐based porosities exhibit complex lateral changes in response to variations in cementation, horizontal compression, and fracturing. Porosities at the prism toe are lower than in reference sediments, whereas porosities landward of the toe are slightly higher than those of reference sediments.

Analogue model experiments on the formation of accretionary prism

The Journal of the Geological Society of Japan, 2006
スケールアナログモデル実験（以下モデル実験と略）は，地質構造の形態やその形成過程を検討するための優れた手法である．自然現象である地質構造形成過程を縮小して，それと物理学的に等価な現象を実験室で再現するためには，相似律と呼ばれる理論に基づいてサイズや物性を変更する必要がある．上部地殻の岩石変形挙動を脆性破壊で近似した場合，相似律によると実験材料を乾燥粒状体（砂やガラスビーズなど）にする必要がある．今回のミニスクールでは，実験理論である相似律と実験材料の物性に関して概略を説明した後，実際に乾燥砂を使ったモデル実験を行って，モデル化した付加体形成過程を観察する．

Assessing the Risk of Potential Tsunamigenic Earthquakes in the Mentawai Region by Seismic Imaging, Central Sumatra

Geochemistry, Geophysics, Geosystems
In the marginal regions along subduction zones, oceanic plates subducting beneath continental plates produce the largest number of earthquakes on Earth and sometimes devastating tsunamis.
