The progress of geological research in Tasmania since 1902

On the occasion of the last meeting of this Association in Hobart the late W. H. Twelvetrees presented a paper entitled "The Outlines of the Geology of Tasmania." A period of eighteen years has elapsed since that paper was prepared, and a great advance has been made in our knowledge of the geology of Tasmania during that interval. It, therefore, seems desirable to take the opportunity afforded by the reassembly of the Association in Tasmania of summarising our progress - to take stock of our knowledge and to see what problems still await solution.
It must be stated at once, however, that in spite of the great amount of work accomplished during the period under review, the result, when viewed in relation to the complete geological survey of Tasmania, is to some extent disheartening.
This was particularly apparent when the preparation of the Geological Sketch Map of Tasmania was undertaken in 1914 by the Geological Survey of Tasmania. When there had been plotted on the base map the geology of the areas of which geological surveys had been completed, the greater portion of the State still remained blank, and to produce the map as ultimately published, the information contained in R. M. Johnston's original geological map was utilised with sundry modifications.
