  1. Metamorphic Rocks Earth and Space Science

  2. Metamorphic Rock – changed rock - Rock formed when other rocks are changed due to heat, pressure, and or chemically - Minerals in the rocks change to different minerals (metamorphosed) - Most common methods 1.Heat \ *not enough heat to melt the rocks 2. Heat and pressure / Causes a chemical change to occur ex. Original rock Metamorphic rock Limestone ----Marble Shale ----Slate

  3. Slate • Used to be Shale • Has layers = FOLIATED • Very flat appearance • Our sample is dark grey, but can be one of several colors

  4. Marble • Used to be Limestone • Has NO layers = UNFOLIATED • Can see the crystals in our sample, but can be polished as well • Our sample is white, but can be one of several colors, or a mix of colors

  5. Schist • Used to be Slate • Has layers = FOLIATED • Very flat, thin, crinkly appearance • Our sample is goldish colored, but can be one of several colors

  6. Gneiss • Used to be Schist or Granite • Has layers = FOLIATED • Our sample has black bands / layers with some visible crystals • Our sample is greyish pink with black stripes, but can be one of several colors

  7. Quartzite • Used to be Quartz sandstone • Has NO layers = UNFOLIATED • Rough appearance with tiny crystals • Our sample is white to grey to pink, but can be one of several colors, or a mix of colors
