SOIL CLASSIFICATION–Metamorphic

METAMORPHIC ROCK 

Any Type of Rock That is Buried Beneath the Earth Surface and is Exposed to High Pressure and Temperature.  Metamorphic Rock is Its Most Stable In Its Most Compact Form.

GENERAL INFORMATION ON METAMORPHIC ROCK

  • Metamorphic Rocks Come From the Transformation of Existing Rock Types.
  • The Process is Referred to as Metamorphism and is Created by Great Heat or Pressure Within the Earth.
  • Metamorphic Rock Make Up a Large Part of the Earth Crust and a Small Part of the Earth Surface.
  • Any Type of Existing Rock Can Becomes Metamorphosized…Igneous, Sedimentary or Existing Metamorphic Rock.
  • General Types of Metamorphic Rock- Gneiss, Schist, Slate
  • General Terms- Primary/ Parent Rock.
  • Foliated- Refers to the Repetitive Layering In Metamorphic Rocks. Each Layer Can Be as Thin as a Sheet of Paper or Be a Foot to a Meter Thick.
  • Non-Foliated- One Piece, With No Layering.
  • **Refer to “TERROIR/ Plate Tectonics” For Additional Information On Metamorphic Rocks.

5 PRECIPITATED SALTS- Oxides, Carbonates, Sulphates, Phosphates, Chlorides

  • Aridisol- From Deserts and Semi-Arid Climates, Low Organic Matter.
  • Moranic- Glacially Formed Accumulation of Unconsolidated Glacial Debris.
  • MINERALS FOUND IN SOILS
    • Calcium/  Helps Neutralize PH.
    • Iron/  Essential for Photosynthesis
    • Magnesium/  Important For Chlorophyll
    • Nitrogen/  Helps Form Nitrates
    • Phosphates/  Encourage Root Growth
    • Potassium/  Helps Vine Metabolism
