Overview

  • Examines the peculiar stranded microstructures created under conditions of high temperature and low pressure, as can occur in shallow basaltic intrusions, and sometimes in meteorites, lightning strikes and combustion of carbonaceous matter
  • Describes the pyrometamorphic qualities of fused rocks termed buchites, paralavas, clinkers and fulgarites
  • Analyzes disequilibrium reaction kinetics with metastable and mineral crystallisation
  • Offers a comprehensive survey of a little known subject that has important applications in petrology

About this book

Pyrometamorphism occurs at very high temperatures (800 - > 1000 °C) and low pressures (< 2 kb) and typically results in the formation of "burnt" and fused rocks termed buchites, paralavas, clinkers and fulgarites. It is typically associated with shallow basaltic intrusions (contact aureoles, xenoliths,) combustion of carbonaceous matter, lightning strikes, and is also found in meteorites. During pyrometamorphism, the sequence of heating and cooling is greatly condensed favouring the preservation of a variety of stranded reaction microstructures that reflect disequilibrium reaction kinetics with metastable and mineral crystallisation.
