From: Shock demagnetization in an ambient magnetic field at the Dhala impact structure, India
a Quartz with Ballen structure in impact melt rock, b Planar deformation features embedded in impact melt rock. c Titanomagnetite (Ti-Mag) oxidized to titanohematite (Ti-Hem) along the margins in impact melt rock. d Monomict breccia with angular clasts of fractured granitoid embedded within a fine-grained matrix. e A clast of monomict breccia consisting of plagioclase (Plg) and quartz (Qtz) grains. f Unshocked granite with plagioclase (Plg) altered to sericite, quartz (Qtz), and biotite (Bio). g Unshocked diorite presenting interlocking texture of plagioclase (Plg) and hornblende (Hbl).
