Investigate how hydrothermal alteration leads to the formation of deposits of valuable minerals like gold, silver, and copper.
This investigation will help you to:
Examine the geologic map of Ohio.
Examine the legend of a geologic map of Ohio and your list of metamorphic rocks found in the region covered by the map.
Write a one or two paragraph description about the events and evidence for metamorphism in your local area.
Investigate how hydrothermal alteration leads to the formation of deposits of valuable minerals like gold, silver, and copper.
Formation of Metamorphic Rocks
- Metamorphic Rocks-Physical Geology - TERC
This is an overview of how metamorphic rocks form.
Deformation in Metamorphism
- Metamorphism and Metamorphic Rocks - Tulane University
Find out happens when temperature and pressure deform a rock. Description includes clear black and white diagrams to support explanation.
Foliation in Metamorphic Rocks
- Metamorphic Atlas of Igneous and Metamorphic Rocks, Minerals and Textures -California State Polytechnic University
Read the definitions of foliated and non-foliated metamorphic rocks. This site also has a helpful chart to demonstrate the different type of foliations.
