Mechanisms of sill and dyke intrusion.
Mechanisms of sill and dyke intrusion require an understanding of fracture growth,stress distributions and intensities, dilation,intrusion rates, hydraulic pressure,host-rock effects,en echelon fracture arrays,and flow ...
The petrology and geochemistry of the Merensky reef in the Rustenburg area.
Four Merensky reef underground exposures of different reef thickness, representative of the lithological variations exposed in mining, have been drilled and mapped. The relationship of the Merensky reef to the underlying ...
