The Hercynian ore deposits from the Catalonian Coastal Ranges
reservas, similares procesos metalogenéticos habrian actuado en el Paleozoico Inferior del Brea. La deformación y el metamorfisme regional hercinicos no han actuado en este sector como un importante reconcentrador de menas, y la mayor parte de indicios epigenéticos Many mineralizations, showings and geochemical anomalies de edad tardihercinicaestán relacionados alas células hidrotermales have b...
متن کاملNickel ore grinding energy determination
This study describes the application of an empirical method to estimate the energy consumption in laboratory of the primary grinding of nickel ore with a specific mineralogical texture. This method developed by Donda was previously used in iron ore from the Iron Quadrangle (Minas Gerais, Brasil) with the same purpose. Through the grinding test, performed under standard conditions and based on t...
متن کاملBiogenic non-crystalline U(IV) revealed as major component in uranium ore deposits
Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV) species in an undisturbed U roll-front ore deposit in Wyoming...
متن کاملRb-Sr dating of sphalerites from Mississippi Valley-type (MVT) ore deposits
Mississippi Valley-type (MVT) ore deposits arc epigenetic carbonate-hosted Pb-Zn deposits that contain galena, sphalerite, fluorite, bar&e, dolomite, calcite, and quartz. Although they are thought to form from basinal brines, their exact origins are still unclear, partly because of the scarcity of reliable geochronological data. Rb-Sr dating of sphalerites has recently been shown to be a promis...
متن کاملRapid sequestration of rock avalanche deposits within glaciers
Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks. The magnitude-frequency of these landslides and their long-term ability to lower mountains above glaciers is poorly understood; however, small, frequent rockfal...
