Kashmir White Granite (garnetiferous granulite, Mesoproterozoic, ~1.4 Ga; Madurai District, Tamil Nadu State, Eastern Ghats Orogenic Belt, India)
Kashmir White Granite - an attractive garnetiferous granulite from India that was metamorphosed during the early Mesoproterozoic (~1.4 billion years ago). The rock has feldspar (white), quartz (grayish), garnet (deep red), and biotite mica (black). This material is quarried at several localities near Melur Taluk (for example, Keelavalavu, Malampatti, Navinipatti, and Tirukalambur), Madurai District, southern Tamil Nadu State in the far-southern Eastern Ghats Orogenic Belt of far-southern India.
Granulite is a term that modern metamorphic geologists don’t seem to like or use for a rock type any more. Traditionally, granulites were considered to be very high-grade metamorphic rocks having a crystalline texture with ~same-sized crystals that are not large. Granulites lack obvious foliation at a fine scale, but do show a weak gneissic foliation at a coarse scale. Several commercial decorative “granites” are actually granulites.
