Kinds of <strong>Metamorphic</strong> <strong>Rocks</strong><br />
• Slate - low grade metamorphosed shale;<br />
very fine grained; slaty cleavage should not<br />
be confused with bedding planes.<br />
• Phyllite - next step up from slate, larger<br />
mica grains give the rock a luster.<br />
•Schist- a strongly foliated rock with large<br />
grains of platy minerals. Named for its<br />
minerals; e.g., chlorite schist.
