A granite batholith, is a large granitic body made up of multiple intrusions of igneous rock. Enchanted Rock, the topographic feature, is located near the southeast margin of the Enchanted Rock batholith [and is marked with a star]. The white lines within the red granite body indicate the orientation of a flow foliation defined primarily by elongate potassium feldspar crystals. The black lines around the body are the traces of large folds in the surrounding rock. Multiple intrusions? Yes, more than one type of granite makes up the Enchanted Rock Batholith. http://uts.cc.utexas.edu/~rmr/E-rock/ERB.html QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture.
