E.F. Heneage, a British geologist residing in London, was a Fellow of the Geological Society of London. In 1902 he read a paper on "The phenomena of the diamondiferous deposits in South Africa" before the (British) Institution of Mining and Metallurgy. The paper was published in the institution's Transactions (Vol. 13, pp. 115-127). Three years later he attended the joint meetings of the British and South African Associations for the Advancement of Science in South Africa and, although he was not a member of either association, read a paper at the Johannesburg meeting on 1 September 1905 titled "A consideration of the archaean period of the continents of North America and South Africa, with reference to mineral occurrences". This paper was included in the Addresses and papers... (Vol. 2. pp. 10-18) published after the meeting. He noted that southern Africa, like North America, has a basal complex of granite, gneisses and schists, similarly folded and contorted, and exhibiting the same evidence of having been subjected to great dynamic forces. His own observations indicated that the conclusion of J.A. Chalmers* and F.H. Hatch*, published in 1895, that the gold-bearing schists of Matabeleland were formed from dolerite intrusions through fissures formed by the folding of the granite crust, probably applies also to the auriferous schists found in the Transvaal. These schists were described by Heneage and W.G. Holford* in "Notes on the occurrence of gold in primary formations", published in the Transactions of the South African Association of Engineers in 1905. At this time Heneage was a member of the Geological Society of South Africa.
