Different hypotheses, invoked during the first half of the last century, involved, (1) assimilation between different magma types and rocks (Daly 1910, 1933; Shand 1931), (2) Subtraction of Eclogite from a Picrite or Peridotite Magma (Holmes 1932; O’Hara and Yoder 1967), (3) gaseous transport (Kennedy 1955), (4) zone refining process (Harris 1957), and (5) partial melting of phlogopite–richterite-bearing peridotitic mantle (Gupta and Yagi 1980).
