Nature, Origin and Evolution of Lamprophyre Melts

  • N. M. S. Rock


Petrogenetic theories for lamprophyres are legion, largely of historical interest, and are reviewed by Rock (1977,1984,1986,1987a,1989a), R.H.Mitchell (1986) and Bergman (1987). This chapter concentrates on: (1) the nature of lamprophyre liquids; (2) genetic unity and diversity; (3) the probability that lamprophyres represent primary melts (Appendix B), or parent melts to a range of more evolved (intermediate-felsic) rock-types. Admittedly, little more can be done at present than posing some fairly intractable questions and outlining critical genetic constraints; satisfactory answers will have to await further work.
