Spatial and temporal evolution of fluids in hydrothermal ore deposits
… typically have vertical extents of several hundred<br />meters and their geochemical characteristics (e.g. mineral assemblages) vary considerably<br />over that vertical extent. As a consequence the expression in outcrop varies depending on<br />the level of erosion. Therefore understanding the …

Silicate Melt Inclusions in Igneous Petrogenesis
… homogeneous glass representative of magma stored at depth before eruption. Melt inclusions are difficult to recognize in quartz phenocrysts from porphyry copper system because they are crystalline and hidden by exsolved magmatic volatiles. The inclusions range in size from less than 5 to over …

Geochemical studies of earth materials
… chalcopyrite-bearing fluid inclusions from the Red Mountain, Arizona, porphyry copper prospect have been used to experimentally document the movement of hydrogen into and out of fluid inclusions in quartz. Chalcopyrite daughter minerals in inclusions do not dissolve during heating studies of "as …
