Summary

[edit]
Description

"Delicatus Ice Granite" - graphic granite in pegmatitic granite, attributed to Brazil with creamy-colored & white potassium feldspar, light gray to medium gray quartz, and black biotite mica. The small, scattered red spots are garnet (click on the photo to zoom in & look around).

Granites having a graphic texture (runic texture) consist of potassium feldspar and quartz crystals that interpenetrate in a way that somewhat resembles ancient writing, like Cuneiform or sometimes Arabic. Such rocks are graphic granites (a.k.a. runic granites; runites). Graphic granite is a not-uncommon component of pegmatites.

Some decorative stones are pegmatitic granites, and large slabs of such rock, such as this one, often have areas of graphic granite. The variety shown here is not entirely graphic granite.
