– In the North China block, Cretaceous extensional tectonics is expressed by numerous syntectonic plutons bounded by ductile normal faults and several metamorphic core complexes (MCC). Cretaceous half-grabens filled by continental terrigenous deposits are widespread. The examples of MCC from South Liaoning Peninsula, Yiwulüshan, Hohhot as well as the Yunmengshan syntectonic pluton spread along ...

Abstract A detailed geochronological study was conducted on zircons from a diorite sample of the Posets pluton (Axial Zone, Pyrenees). The extracted igneous constrain emplacement to 302 ± 2 Ma and 301 3 Ma, by means U–Pb sensitive high-resolution ion microprobe (SHRIMP) laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses, respectively. Considering syn- late-tectonic...

Abstract The Arbus igneous complex (SW Sardinia, Italy) represents a good example of short time lived post-collisional composite pluton emplaced at shallow crustal level in the external zone Variscan chain. almost consists granodiorite and leucogranite rock- suites 304 ± 1 Ma within main NW trending thrust separating metamorphic wedge from fold belt foreland. into dilatational step over connect...

Abstract The Takidani pluton (1·1–1·6 Ma) represents a shallow magmatic reservoir at the base of an exhumed caldera floor. deposits two large caldera-forming eruptions, Nyukawa Pyroclastic Flow Deposit (1·76 Ma; crystal-rich dacite) and Chayano Tuff Ebisutoge Deposits (1·75 sequence crystal-poor rhyolite), are distributed concentrically around pluton. We use major trace element chemistry whole-...
