Metamorphic Rocks
Cards in this deck (16)
- 1Reference Card (feel free to skip)Rock Name: foliated or non-foliated, texture, metamorphic grade, possible protolith (parent rock), defining characteristics (how I identify it).
- 2imageRed Slate: foliated, slaty, low grade, shale
- 3—Mica Shist: foliated, schisty, intermediate grade, slate
- 4—Quartzite: non-foliated, medium-coarse, high grade, sandstone
- 5—Gneiss: foliated, gneissic, high grade, schist
- 6imageGarnet-Mica_Shicst: foliated, schisty, intermediate grade, slate
- 7imageTalc Shist (Soapstone): non-foliated, schisty, low grade, dunite, greasy and might be minty-clear green
- 8imageAmphibolite: foliated, schisty, intermediate grade, gabbro
- 9imageWhite Marble: non-foliated, medium-coarse, low-intermediate grade, dolostone.
- 10imageSerpentine: non-foliated, fine, low grade, peridotite, should be a dark green
- 11imageBlack Slate: foliated, slaty, low grade, shale
- 12imagePink Marble: non-foliated, coarse, high grade, limestone
- 13imagePhyllite: foliated, phyletic, low-intermediate grade, slate, shiny
- 14imageAnthracite Coal: non-foliated, fine, low grade, peat, is a shiny/iridescent but black coal
- 15imageMetaconglomerate: non-foliated, coarse, low-intermediate grade, conglomerate
- 16What is the order of foliated textures from pure rock to low grade to high grade? How might these help us find a protolith?Shale, slate, phyllite, schist, gneiss. A previous one on the chain might be a protolith for the next rock (a shist has a protolith of slate).
