Abstract:
In 1898 Molengraaf discovered the Leeufontein Alkaline Complex and gave a description of a "nepheline-syenite from the farm Leeuwfontein (320) (2, p .89). In the same year Henderson (1, p.45) gave a description of the soda-syenite under the name of “hatherlite” but in 1904 Molengraaf (3) proposed the name "anorthoclase-Amphibole-pyroxene-syenite'' for Henderson's hatherlite.
