A single scientist working alone could not have achieved the significant results of this series of interdisciplinary research projects. The writer of this e-book has been responsible for recording most of the factual observations presented and has examined a very large number of scientific publications to ensure they contain no factual data, observations, or measurements that would contradict or negate the central hypothesis. However he has been privildged to co-ordinate the work of many senior scientists who have contributed basic concepts, ideas, and information that have made it possible to achieve these fundamental and successful far-reaching research results.
Professor A.E. Alexander, Professor of Physical Chemistry, University of Sydney, 1959, identified the siliceous phenocrysts in the Black Angel porphyroid at Tennant Creek as accretions.
Professor S.W. Carey, Professor of Geology, University of Tasmania, 1960 to 1972, emphasised the importance of factual observational data and encouraged the revision of traditional concepts relating to the origin of igneous-looking rocks and mineral deposits in accord with current developments in the physical chemistry of small particle systems.
Professor T.F.W. Barth, University of Oslo, 1965, confirmed that the feldspars in the Tennant Creek porphyroids are of authigenic origin and that their composition is such that a corresponding molten magma becomes a “physico-chemical impossibility”.
Professor T.W. Healy, University of Melbourne, 1967 to 1977, introduced the physico–chemical processes that occur during the diagenesis of sediments: with particular emphasis on the role of colloids and colloidal processes in geology. He conducted the necessary experimental work to demonstrate the formation of accretions in mobilised aqueous pastes.
Dr. Ralph K. Iler, Cornell University and E.I. duPont de Nemours & Co., Wilmington, Delaware, 1984, introduced the aqueous chemistry of silica and the particulate nature of naturally occuring silica polymers and confirmed that the principles of this colloid chemistry were correctly applied in the case of the Tennant Creek porphyroids.
Professor R.L. Stanton, University of New England, Armidale, 1989, published the results of independent studies in which he had used a microprobe analyser to identify the composition of hydrous precursor minerals from which an extensive suite of metamorphic minerals had crystallised.
Professor T.W. Healy and his colleagues at Advanced Mineral Products Research Centre (now Particulate Fluids Processing Centre), University of Melbourne, 1998, had adapted an atomic force microscope to measure forces between charged particles to confirm that the particle interactions were as predicted by DLVO theory. Professor Healy personally communicated the results of this outstanding achievement on 2nd July 1999.
Sir John Proud, Chairman and Chief Executive of Peko-Wallsend limited, 1959 to 1975, was primarily responsible for encouraging and financing the research from its early stages. He introduced and took advice from many eminent scientists to ensure that the new approach was properly based on the principles of colloid chemistry and the rheology of aqueous pastes.
Many staff members and executives of Geopeko Limited and CRA Exploration have actually made greater contributions to this research in time and effort and the study of examples but introduction of critical concepts and information on which the whole research program is based are acknowledged above.
