Late Paleozoic magmatism in South China: Oceanic subduction or intracontinental orogeny?

Active continental subduction and crustal exhumation: the Taiwan orogeny

It is generally accepted that continental subduction and crustal exhumation play an important role in the evolution of many orogenic belts. A variety of geological evidence suggests that continental crust is occasionally subducted to depths of tens to perhaps 150 km (e.g. Chopin, 1984; Dewey et al., 1993; Matte et al., 1997). Recently, a series of simulations (Chemenda, 1993; Chemenda et al., 1...

Initiation of the Andean orogeny by lower mantle subduction

شیمی کانی، زمین‌شیمی و سن‌ پرتوسنجی سنگ‌های آذرین نفوذی منطقه کلاته (شمال-غربی خور): شاهدی بر فعالیت ماگمایی تریاس پسین در پهنه ساختاری ایران مرکزی

Dioritic plutons and pinkish alkali-feldspar granitic dikes of Kalateh area (northwest of Khur city) intruded in Neoproterozoic basemental of Jandagh- Arousan complex. Field observations, petrography and geochemical studies indicate that these intrusive rocks have I-type nature and belong to medium-high K calc-alkaline granitiods and also have genetically relationship with each other. Their par...

The Heart of China revisited: II Early Paleozoic (ultra)high-pressure and (ultra)high-temperature metamorphic Qinling orogenic collage

[1] Orogens with multiple (ultra)high-pressure ((U)HP) and (ultra)high-temperature ((U) HT) metamorphic events provide a complex but telling record of oceanic and continental interaction. The Early Paleozoic history of the “Heart of China,” the Qinling orogenic collage, offers snapshots of at least three (U)HP and two (U)HT metamorphic events. The preservation of remnants of both oceanic and co...
