Alphonse Briart (1825–1898) was supervisor of the coal mines at Bascoup and Mariemont near Morlanwelz in the Hainaut province of Belgium, and a geologist who studied that region. During the period 1863-1896 he and published a number of books and papers describing fossils and geological structures found near Mons. They devised theories - now generally accepted - as to the geological history of the region. After Cornet's death in 1887, Briart continued to write alone.
