Introduction MAG2007 was the first international workshop devoted to bringing together igneous and gas geochemists working on volcanology-related topics. It was held at the Institute of Earth Sciences, Academia Sinica, and at Taiwan’s East Coast, from 22 to 27 April 2007, and hosted an international group of some 45 leading experts and students of volcanology and igneous and gas geochemistry.

New U-Pb ages for detrital and igneous zircons constrain the depositional age and sedimentary provenance of the Beardmore Group, a siliciclastic succession that records transformation of the East Antarctic margin during Rodinia breakup and subsequent Gondwana amalgamation. We divide rocks previously mapped as the Beardmore Group into (1) an inboard late Neoproterozoic assemblage (probably ≤670 ...

" Within an area of 900 km2 in the southern Snake southern Snake Range of eastern Nevada. The granitoids Range, White Pine County, Nevada, six igneous masses exposed range in age from Jurassic through Cretaceous to are well ex...

“This continuity disappears, however, if one considers individual parts of the [Central American] chain and examines separate groups of volcanoes within a restricted volcanic field. It then becomes apparent that the continuity of the province as a whole is the result of grouping excessively large segments of the chain.” A.R. McBirney: Compositional variations in Cenozoic calcalkaline suites of ...

Abstract The Pleistocene (2.2–1.5 Ma) Koloula Igneous Complex (KIC) on Guadalcanal in the Solomon island arc consists of a low-K calc-alkaline sequence ultramafic to felsic plutonic rocks. We present whole-rock major and trace element Sr–Nd-Pb isotope data, as well mineral compositions that record magmatic evolution complex. intrusive is grouped into two cycles, Cycle 1 2, comprising gabbroic o...
