15 صفحه اولMelt inclusions from Marianas arc lavas: implications for the composition and formation of island arc magmas
We have measured the major and trace element compositions of a suite of olivine-hosted melt inclusions in basaltic lavas from the islands of Agrigan and Guguan (one sample each) from the Mariana arc, part of the larger Izu–Bonin–Mariana system. The two lava samples examined show distinctly different chemical signatures that are considered to represent the dominance of sediment melt (Agrigan) or...
متن کاملMechanism for Coherent Island Formation during Heteroepitaxy
Monte Carlo simulations are reported for an atomistic model of heteroepitaxial growth. Dislocations are excluded but lattice misfit is assumed to encourage atom detachment from islands by reducing the barrier for this process by a morphology-dependent strain
متن کاملTectonic Evolution of the Japanese Island Arc System
■ Abstract Growth of the Japanese arc system, which has mainly taken place along the continental margin of Asia since the Permian, is the result of subduction of the ancient Pacific ocean floor. Backarc basin formation in the Tertiary shaped the presentday arc configuration. The neotectonic regime, which is characterized by strong eastwest compression, has been triggered by the eastward motion ...
متن کاملThe Effect of Raw Material Ratios on the Fe-TiC/Al2O3 Composite Formation Mechanism
Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites which are used as cutting tools. Few publications can be found in the literature that discusse the effect of molar ratio of aluminum and graphite on the Al2O3/TiC–Fe formation mechanism. Therefore, the present research is designed to make the issue clear. To achieve this goal, at first, the mechanism o...
