Magnetite skarn (Precambrian; Tilly Foster Iron Mine, near Brewster, New York State, USA) 5
This iron ore sample is from a magnetite body at New York State's Tilly Foster Iron Mine. The sample is dominated by magnetite (= Fe3O4, iron oxide) with serpentine and chondrodite. The deposit has been interpreted as a skarn, which is a contact metamorphic deposit. Skarn rocks have a crystalline texture and form by heating and addition of elements (metasomatism) to country rock in the vicinity of an igneous intrusion (batholith, stock, sill, dike, laccolith). The mineralogy of skarns varies and depends on the chemistry of the host rock and the intruding magma.
Locality: Tilly Foster Iron Mine, northwest of the town of Brewster Heights, southeastern New York State, USA

MagnetitMagnetit, veraltet auch als Magnetstein, Magneteisen, Magneteisenstein oder Eisenoxiduloxid, ist ein sehr häufig vorkommendes Mineral aus der Mineralklasse der „Oxide und Hydroxide“ mit der chemischen Zusammensetzung Fe2+Fe3+2O4 (vereinfacht Fe3O4). Magnetit ist damit chemisch gesehen ein Eisen(II,III)-oxid. .. weiterlesen
