Abstract
In this paper, we present arguments for the presence of optically active Ti3+ in the structure of low iron pyroxenes to explain the strong 0.49-μm absorption band in spectra of E[II] asteroids. Such an interpretation supports the idea that E asteroid material is formed at high temperature in a strongly reducing medium. We also discuss the possibility of high temperature and hydrated rocks coexisting on some E asteroids. Our discussion is based on the idea of collisional evolution of aubrite parent bodies that was presented by Keil (1989).
