Abstract
IN no other part of the world is the work of the geologist linked up with such varied interests as in the little strip—some fifty miles long—of high tableland in the Transvaal known as the Witwatersrand, on which are situated some sixty producing gold-mines with an annual output of 350 tons of fine gold, worth 35,000,000l.; and, indeed, in no other district has the geologist such opportunities for prosecuting his researches as are afforded by the innumerable prospecting trenches, shafts, and deep borings that have been put down on the Rand in the search of extensions, along the strike and on the dip, of the auriferous conglomerates. Hundreds of thousands of pounds have been spent on prospecting work of this nature. In one area alone near the Springs, in the East Rand, the writer of this review had the technical supervision of a series of deep borings, costing above 30,000l., and successfully located the eastern end of the Witwatersrand syncline, with its valuable gold-bearing seam there concealed beneath a thousand-foot cover of the later unconformable Dolomite formation.
