...Donald Raymond Hunter; J. G. Urie Abstract Deposits of kaolin in the Mahlangatsha mountains of Swaziland were derived from dolerite dikes in quartzites of the Precambrian Mozaan series. The dikes were intruded along faults prior to emplacement of biotite-microcline granite, hydrothermal solutions...

...C. C. Reeves Abstract Field investigation and sporadic drilling indicate greater kaolin clay reserves at Mesa-Alta than previously suspected. In fact, high-grade kaolin clay has been found at several different localities in the Mesa Alta area but topography, poor outcrops, and heavy forest cover...

... of the kaolinitic sediments. The color of the reddish zone is due to oxidation above the water table of Fe compounds. Throughout large areas the kaolin-bearing sands rest unconformably on the middle Miocene Hawthorne formation. On the eastern side of the Lake Wales Ridge, the kaolinitic sediments in some localities...
