Arthur Lewis Hall FRS (10 January 1872 – 13 August 1955) was a British geologist, who worked in South Africa for most of his career.
[1] Hall's geological work included mapping of the rocks outcropping across the vast Bushveld complex - an area that is now recognised as a classic example of a layered intrusion, and which represents the solidified remains of an ancient magma system.
Hall's work also extended to studies of the mineralisation and mineral potential of the Bushveld complex, and mapping of the gold mining district of Barberton.
[4] In 1922, Hall and Gustaaf Molengraaff helped to guide the Shaler Memorial Expedition team of Reginald Daly, Charles Palache and F E Wright to the Bushveld complex.
[5][6][7] This expedition drew attention to extraordinary nature of the Bushveld complex, and to the work that had already been done there by Molengraaf and Hall over the previous two decades.
Hall was proposed by Arthur Rogers, director of the geological survey of South Africa, supported by geologists including OT Jones, Alfred Harker, Albert Seward and John Flett.
He also published a vast compendium of analyses of rocks, minerals, ores, coal, soils and waters from southern Africa, and updates to his series of monographs on the bibliography of South African geology, until his failing eyesight meant that he had to stop.
