This new paper presents the results of petrography, chemistry, and stable isotopes of four silicocarbonatites from rift settings (Lemitar Mts, New Mexico; Iron Hill, Colo, Sukulu and Tororo,Uganda) and presents a model that explains the origin of silicocarbonatites from parental carbonated silicate melts vis liquid immiscibility. This study explains the link between silicate and carbonatite melts found throughout the world.
