Magmatic-Hydrothermal Events, Mineralogy and Geochemistry of Tourmaline Breccia in the Giant Río Blanco – Los Bronces Porphyry Copper Deposit, Central Chile

Autor: Hohf Riveros, Michael

The Río Blanco–Los Bronces (Chile) is one of the richest endowed porphyry copper-molybdenum districts worldwide, where about 20% of the known mineralization is hosted by tourmaline-cemented hydrothermal breccia. This work seeks: (1) to find a rela

Vein mineralizations of different age and formation were studied in the northern Eifel area and its foreland. The focus was put on microstructure, geochemistry and isotopic composition to characterize discrete fluid flow events and to date their gene

Lösungskinetik von Gips und Anhydrit

Autor: Jeschke, Alexander A

The dissolution kinetics of gypsum and anhydrite have been measured under various conditions. For gypsum an almost linear rate equation R=ks1(1-c/ceq)n1 is valid, where R is the surface rate, n1 1 is the kinetics order, c is the total calcium concent
