Noble gases within the crust originate from three main sources: the atmosphere, introduced
into the crust dissolved in groundwater; the mantle, in regions of magmatic activity; and …

Gold-bearing quartz vein systems in metamorphic terranes are one of the most important
types of lode gold resource. Major vein-type Au mineralisation of this style in central Victoria …

This paper reports systematic changes in mudrock composition through time on a single
continental crustal block. The changes reflect both sediment recycling processes and …

China produces about 450 t Au per year and has government stated in-ground reserves of
approximately 12,000 t Au. Orogenic gold, or gold deposits in metamorphic rocks, and …

The solubility of quartz in H 2 O has been determined experimentally from 5 to 20 kb and
500 to 900° C. The results double the pressure range over which the molality of aqueous …

Systematic examination of published sedimentary and metamorphosed pelite analyses has
revealed evidence of significant mass transfer and volume strain during regional …

Abstract Comparison of mass transfer patterns, geometry and microstructures developed
within and around veins allows the interpretation of processes of fluid flow during …

Both sediment recycling and first-cycle input influence the composition of clastic material in
sedimentary systems. This paper examines conceptually the roles played by these …

The relationship between the supersaturation at the point of crystallization and the rate at
which supersaturation increases has been studied from nucleation experiments on barite …

Many large Archaean epigenetic gold deposits show a broad spatial relationship to regional
lineaments in greenstone belts, although in detail they are sited in subsidiary brittle-ductile …
