Mineralogy ?? Other Disciplines

• Structure Recrystallization new fabrics
• Tectonics Dehydration reactions release fluids
  trigger quakes
• Geochronology Datable minerals hold both parent
  and daughter isotopes
• Petrology Partition or order/disorder of
  elements serves as geothermometer geobarometer
  recording P,T conditions

4
Mineralogy ?? Other Disciplines

• Geochemistry Composition of minerals records
  reservoirs, fluids and processes
• Meteoritics Composition, age conditions of
  early solar system early thermal separation of
  atmophile, chalcophile siderophile elements
• Planetary Studies Lunar rocks Apollo 11 16,
  Shergottites Mars Rover spectra

5
Mineralogy ?? Other Disciplines

• Paleontology Fossilization replacing organic
  matter by minerals silica, pyrite, calcite,
  apatite
• Geomicrobiology Archae bacteria nannobacteria
  extremophiles depositing minerals. Sulphate
  reduction to Sulphide
• Environmental Heavy metals cycling, acid rock
  drainage, filtration, fixation, soil chem
