    Geopressure zones as proximal sources of hydrothermal fluids in sedimentary basins and the origin of Mississippi Valley-type deposits in shale-rich sequences

    By A. D. Fowler, M. T. Anderson

    A phenomenological model is presented that relates Pb-Zn mineralisation to proximal geopressure zones. Typically, geopressure zones (GPZ) consist of masses of undercompacted sediment encapsulated with

    Silver solubility in sodum silicate slags

    By Xiao Min You, D. R. Swonbourne

    Smelting of Cu anode slimes involves the use of a slag to hold the oxidised Cu, but some Ag is also inevitably oxidised to the slag. The solubility of Ag in sodium silicate slags at 1 100 and 1 150 de

    Design methods to control violent pillar failures in room-and-pillar mines

    By R. K. Zipf

    The sudden, violent collapse of large areas of room-and-pillar mines poses a special hazard for miners and mine operators. This type of failure, termed a cascading pillar failure, occurs when one pill
