The state of the upper mantle beneath southern Africa
... We construct the 3D upper mantle model for southern Africa employing the two-step procedure previously used for Australia (Debayle and Kennett, 2000b), eastern Africa (Debayle et al., 2001) and Siberia (Priestley and Debayle, 2003). We first use the automated version (Debayle, 1999) of the Cara and ...

In the slope and nose-like structure periclinal parts, there are good conditions for forming lithologic oil reservoir and great potential for exploration. For a detailed study of the sedimentary characteristics of lower Es3, we applied analysi ...
