AbstractThe debate concerning eastward versus westward subduction along the western margin of Mesozoic North America involves three main arguments: The tomography argument (westward) claims subducted slabs are observed by tomographic processing of seis…
AbstractThe age, emplacement, and metamorphic history of the garnet amphibolitic and retrogressed eclogitic slices in the Menderes Massif (Eastern Aegean) have been a matter of debate since the 1990’s. Late Cretaceous garnet amphibolitic and retrogress…
AbstractThe Late Paleozoic–Mesozoic Mongol-Okhotsk orogenic belt marks the final aggregation of East Asia. The geodynamics of the Mongol-Okhotsk oceanic plate subduction are still poorly understood due to its curved orogenic architecture, complex kinem…
AbstractHighly evolved granitic melts typically experience late-stage melt-melt and fluid-melt immiscibility as well as fluid-melt and fluid-rock interaction. These processes are particularly important in the formation of deposits of the rare metals Nb…
AbstractThe Cretaceous/Paleogene (K/Pg) boundary is marked by one of the largest mass extinctions in Earth’s history, with geological evidence for this event being expressed in hundreds of locations worldwide. An extensively studied section located nea…
AbstractAtmospheric circulation in western China significantly affects the inland climate of Asia. Constraining the provenance of eolian sequences can provide robust evidence for dust-transport pathways, and thus the evolution of paleo-atmospheric circ…
AbstractThe transition from the terminal Ediacaran to early Cambrian (ca. 550–530 Ma) witnessed both the decline of Ediacaran-type soft-bodied and skeletal biota and the rapid diversification of Cambrian-type skeletal biota, which dominate the Terreneu…
AbstractWe present the late Holocene eruption history of the poorly known Doña Juana volcanic complex, in SW Colombia, which last erupted in the twentieth century. This represents a case study for potentially active volcanism in the rural Northern Ande…
AbstractMany intraplate oceanic islands undergo “rejuvenated” volcanism following the main edifice-building stage. Honolulu features Hawai‘i’s most recent rejuvenated volcanism. K-Ar dating of Honolulu volcanism suggests that it started at ca. 750 ka a…
AbstractExposures of enclave-bearing granitoids can provide rare opportunities to directly evaluate the connection between compositional variability and the depth of origin of arc magmatic rocks. The ~1000 km long Gangdese batholith is a composite bath…
