There is no more imposing figure in the history of Australian anthropology than W.E.H. ('Bill') Stanner (1905-1981). While some of his contemporaries produced more ethnography, none matched his skill and eloquence in describing the life-worlds of Aboriginal people. While others of his age were just as closely involved in arguing for the defensibility of Aboriginal society, none did so with such convincing passion. With these two legacies in mind, anthropologists in the here and now would be hard put to describe Stanner's oeuvre in either/or terms. He is best remembered for his scintillating, sympathetic analyses of Aboriginal myth, ritual and local organisation, together with his trenchant critiques of Durkheim and Freud.

The thermal stability and thermal decomposition pathways for synthetic iowaite have been determined using thermogravimetry in conjunction with evolved gas mass spectrometry. Chemical analysis showed the formula of the synthesised iowaite to be Mg6.27Fe1.73(Cl)1.07(OH)16(CO3)0.336.1H2O and X-ray diffraction confirms the layered structure. Dehydration of the iowaite occurred at 35 and 79°C. Dehydroxylation occurred at 254 and 291°C. Both steps were associated with the loss of CO2. Hydrogen chloride gas was evolved in two steps at 368 and 434°C. The products of the thermal decomposition were MgO and a spinel MgFe2O4. Experimentally it was found to be difficult to eliminate CO2 from inclusion in the interlayer during the synthesis of the iowaite compound and in this way the synthesised iowaite resembled the natural mineral.
