Aeromagnetics and gravity

, 2007
Residual Magnetic Field: This image shows the colour-coded map of the residual magnetic field. The image has a pixel size of 200m which results from gridding of the digititally acquired flight-line survey data. The two main aeromagnetic surveys covering this area were flown between 1975 and 1978.

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.
