Anorthosites and Komatiites

  • Gautam Sen


This chapter covers some unusual rock types that are volumetrically negligible relative to basaltic, andesitic, and granitoid rocks, and yet they are very significant in terms of our understanding of the Earth’s igneous history and constitution and thermal structure of the deep continental lithosphere. It is difficult to present many levels of the detailed observations and inferences that have been made by many authors about each of these rock types, and in this chapter, I present a brief summary of what I consider that an undergraduate student needs to know.
