The Freetown Layered Complex (FLC) is a massive mafic layered intrusion cropping out along the coast of Sierra Leone. The present combined geochemical and geochronological (40Ar/39Ar on plagioclase: 201·7 ± 0·7 and 202·3 ± 2·3 Ma; U–Pb on bad

Exploration of tektite formation processes through water and metal content measurements

Autor: Cin-Ty A. Lee, Nigel Watt, Romain A. Bouchet

Publikováno v: Meteoritics & Planetary Science. 46:1025-1032

Impact events are a significant surface-modifying process on solar system objects lacking frequent resurfacing by atmospheric or igneous processes. To better explore the effects of impacts on surface materials, we measured the water and trace element

In order to elucidate the nature and history of the different geological units in the western USA and correlate geochemical signatures with features identified in seismic models developed from USArray, we compiled from the literature Pb isotope compo

International audience; Mafic volcanism gradually encroaching on the tectonically stable Colorado Plateau in the southwestern United States appears to originate from within Paleoproterozoic lithosphere. New Hf and Nd isotope data strengthen evidence

Copper systematics in arc magmas and implications for crust-mantle differentiation

Autor: Peter Luffi, Emily J. Chin, Rajdeep Dasgupta, Douglas M. Morton, Qing-Zhu Yin, Daphne Jin, Romain A. Bouchet, Cin-Ty A. Lee, Véronique Le Roux

Publikováno v: Science (New York, N.Y.). 336(6077)

Copper-Bottomed Crust The formation of volcanic arc chains near subduction zones brings large amounts of magma from the upper mantle to the crust, contributing to the formation of island chains in the ocean and adding material to continents. Over tim
