2D Seismic Reflection Surveys and Structural Mapping: Faults, Dips and Domes

In the local mineral exploration environment the high resolution imaging capabilities of 2D seismic reflection surveys continue to provide rapid, cost-effective mapping solutions over areas of structural mapping concern not otherwise speedily available from borehole data. This is particularly so where time-lines are short. 2D seismic sections sourced from the Wits Gold, Karoo coal, Canadian diamond and Bushveld platinum exploration sectors demonstrate in particular; • technique versatility in mapping orebodies or marker horizons having a tabular sheet geometry, and satisfying minimum thickness plus physical property requirements • a large spectrum of structural environments ranging from the benign to the complex. This spectrum ranges from flat dips with minor rolls and grabens through large scale wrench and listric faulting, to moderate dips with structural terraces or large grabens above Floor doming.
