Cryptic differentiation in the endemic micromoth Galagete darwini (Lepidoptera, Autostichidae) on Galápagos volcanoes.
To gain insight into the early stages of speciation, we reconstructed a DNA-based phylogeny, using combined mitochondrial (cytochrome c oxidase subunits I and II: 1008 bp) and nuclear (elongation factor 1-alpha and wingless: 1062 bp) markers of populations of the moth Galagete darwini endemic to the Galápagos, which belongs to an insular radiation similar in size to that of Darwin's finches. Ad...
متن کاملLate Neoproterozoic A-type granites in the northernmost Arabian-Nubian Shield formed by fractionation of basaltic melts
Geochemical, isotopic and age constraints support a comagmatic origin for Ghuweir Mafics and the Feinan A-type granites. The two rocks types, named collectively in this paper as the Feinan Ghuweir Magmatic Suite (FGMS), formed between 556 and 572Ma ago according to Rb–Sr whole-rock dating. FGMS has low Sr initial ratios, which preclude a significant contribution of much older crust in the magma...
متن کاملSmall Martian Shield Volcanoes and Terrestrial
Introduction: A number of terrestrial analog studies have focused on characterizing individual lava flows [e.g., 3, 6-7]. Morphometric and compositional information from these features can be used to infer the rheological properties of similar lava flows, the timing and duration of the eruptions episodes, the depth of the magma chambers [2, 12-14], and even the eruptive and emplacement history ...
متن کاملA new model for the growth of basaltic shields based on deformation of Fernandina volcano, Galápagos Islands
a r t i c l e i n f o a b s t r a c t Keywords: basaltic shield InSAR data sill radial dike circumferential fissure Galápagos Islands Space-geodetic measurements of surface deformation produced by the most recent eruptions at Fernandina – the most frequently erupting volcano in the Galápagos Archipelago – reveal that all have initiated with the intrusion of subhorizontal sills from a shallow ma...
متن کاملThe H2O solubility of alkali basaltic melts: an experimental study
Experiments were conducted to determine the water solubility of alkali basalts from Etna, Stromboli and Vesuvius volcanoes, Italy. The basaltic melts were equilibrated at 1,200°C with pure water, under oxidized conditions, and at pressures ranging from 163 to 3,842 bars. Our results show that at pressures above 1 kbar, alkali basalts dissolve more water than typical mid-ocean ridge basalts (MOR...
