Figure 5B. This rock has patches and streaks of a pale apple-green mineral (diopside) and a cinnamon-brown mineral (garnet), which grew in response to heat during metamorphism. These minerals have compositions which indicate the rock has a relatively high content of calcium and silica, and was probably derived from a sandy limestone (or limy sandstone).
