... plutons) have shown these intrusive bodies to be approximately 3213 to 3236 Ma. Also adjacent to the metavolcanic rocks of the Nelshoogte Schist Belt is a sequence of metamorphosed ultramafic-mafic cumulate rocks that make up the Stolzburg Layered Ultramafic Complex. This Complex, which is fault bounded...
