Kaolinite claystones that are similar in structure, texture and composition to the kaolin tonsteins of Western Europe, and to some of the flint clays of North America, are associated with the Wongawilli Seam in the southern part of the Sydney Basin, where they form thin persistent bands within the coal and somewhat thicker deposits immediately overlying the seam. The thin bands within the coal are fine grained and consist of brecciated to pelletal clasts composed of well-ordered kaolinite set in a matrix of similar composition. The thicker deposits overlying the seam are much coarser grained and appear restricted in occurrence to the basin margins. They contain a predominance of oolites with kaolinite clasts bonded by a relatively sparse matrix and in places, remarkable 'outgrowths' of vermicular kaolinite. The origin of the deposits is discussed, and it is concluded that most of the unusual features of these claystones can be ascribed to a fluvial environment. |
