Changing Sources of Magma Generation Beneath Intra-Oceanic Islands Arcs: An Insight From the Juvenile Kohistan Island Arc, Pakistan Himalaya [PDF]

, 2006
The Kohistan arc, situated in the Pakistan Himalaya, is a Cretaceous intraoceanic island arc which was initiated during the northward movement of the Indian Plate. The arc was sutured to Asia at ca. 100 Ma.

Peculiarities of Subduction in the Junction of the Kuril–Kamchatka and Aleutian Island Arcs [PDF]

Doklady Earth Sciences, 2020
The peculiarities of the junction between the Kuril–Kamchatka and Aleutian island arcs are studied using different techniques and experimental data. The models of medium structure that were obtained by using surface wave tomography and studies of S-wave anisotropy in the asthenosphere beneath the subduction plate detected an ascending asthenospheric ...

Active faulting in Sredinny Range, Kamchatka Peninsula

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The paper presents the results of remote sensing interpretation of active faults of the Sredinny Range of Kamchatka. The use of remote sensing data allowed us to identify fault scarps and magma-conducting fractures, expressed in the topography by chains ...
