Evidence from adakitic rocks for a switch in magmatic source at ca. 460 Ma in the Karamaili Ocean of East Junggar, NW China

Early Paleozoic magmatism can preserve critical geological records related to subduction-accretion in the Central Asian Orogenic Belt (CAOB). Here, we report new geochemical, geochronological and isotopic results for diorites-granitoids in the Karamaili ...

Palaeoproterozoic adakite- and TTG-like magmatism in the Svecofennian orogen, SW Finland

, 2021
The Palaeoproterozoic Svecofennian orogen in the Fennoscandian shield is an arc accretionary orogen that was formed at c. 1.92-1.86Ga. Arc accretion, magmatism and the subsequent continent-continent collision thickened the crust up to c.

Petrology and gold content of adakitic granitoids of usthbelovskii complex in Makarevskii range of Gorny Altai

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the discussed issue is caused by the need of researching petro-geochemistry and petrologic peculiarities of gabbrogranitoid massifs of Makarevskii range which are related spatially to gold occurrence.

Les adakites d'Equateur : modèle préliminaire

, 1997
L'ensemble des roches de 12 volcans quaternaires des Andes équatoriennes (286 analyses nouvelles) présente une signature adakitique, plus ou moins forte selon les appareils. Cette signature proviendrait de la fusion partielle de matériaux basaltiques métamorphisés de la croûte continentale (MORB et/ou basaltes d'arc) sous l'action des remontées ...

Magmatic Evolution of the Panales Caldera: Chemo- mineralogical characterization of the El Torito Dome, Mexico

Boletín Geológico
The aim of the present work is to determine the petrogenetic significance of a dacitic dome in central Mexico, and to establish the correlation with the geological evolution of the eastern sector of the Trans Mexican Volcanic Belt, which traverses the ...

Adakites from Ecuador : preliminary data

, 1996
Les premiers résultats du programme de volcanologie mené en Equateur par l'ORSTOM et l'Institut Géophysique de l'Ecole Polytechnique Nationale (Quito) montrent une forte proportion d'adakites parmi les roches échantillonnées sur les volcans quaternaires. Ces roches résultent de la fusion partielle d'une source basaltique.
