Petrology of the Machangqing complex in Southeastern Tibet: implications for the genesis of potassium-rich adakite-like intrusions in collisional zones

, 2021
Many intrusions with adakite-like affinities in collisional zones have obviously higher K2O contents and K2O/Na2O ratios compared with counterparts in subduction zones.

Origin of Eocene adakitic magmatism in northwest Turkey

Journal of Asian Earth Sciences, 2020
Abstract In this study, we focus on adakitic porphyries, which are rare and recently discovered in the northwest (NW) Turkey. We present a comprehensive dataset including their petrography, geochemistry, and 40Ar/39Ar geochronology to gain insight into the causes, timing, and possible melt sources of adakitic magmatism in the absence of active ...

An overview on the origin of adakites/adakitic rocks and related porphyry Cu-Au mineralization, Northern Luzon, Philippines

Ore Geology Reviews, 2020
Abstract The Philippine island arc is famous for the widely developed large porphyry and epithermal Cu-Au deposits and associated Cenozoic adakites/adakitic rocks. Northern Luzon is one of the most Cu-Au enriched areas in the Philippines, which develops Late-Oligocene to Pleistocene porphyry and epithermal Cu-Au deposits in the Central Cordillera ...

Petrogenesis of Middle Triassic Adakite-like Intrusions in the Asiha Orogenic Gold Deposit, East Kunlun Orogenic Belt, China

, 2023
The East Kunlun Orogenic Belt is considered as one of the important gold mineralization regions in the Tethys tectonic domain. These orogenic gold deposits are related to intermediate-acid intrusions formed at the end of Paleo-Tethys evolution, but the ...

Non-subduction Ichara adakite-like rocks from West Sakhalin (Russian Far East) versus supra-subduction Daisen adakites from SW Japan: Insight from trace-element modelling of sources

Geosystems and Geoenvironment
The Ichara Complex of small intrusions is located on the Late Cenozoic Orlov volcanic field of West Sakhalin, in the area of Lamanon Cape. Andesites and dacites of the Ichara Complex and Orlov volcanic field show adakite-like signature (high Sr/Y, low ...
