Review Guide For Exam 2

  • Igneous Mineralogy

  • Bowen’s Reaction Series

  • Silicate sub-classes; mineral structures

  • and compositions

  • Polytypes

  • Solid solutions

  • Twinning; simple , polysynthetic,

  • penetration

  • Zoning


Igneous Rocks

Textures and cooling history

Rock names; compositional

classification and mineralogical

Origin of magmas; decompression,

flux and thermal melting

Gas content and viscosity; controls

and consequences

Water content; role in melting and

explosive volcanism


  • Tectonic environments

  • Basalts; MORB, OIB (intraplate), Flood

  • Basalts and LIPs, Subduction Zones

  • Know the controls on the production

  • of calc-alkaline versus tholeiitic

  • basaltic magmas

  • Understand layered intrusions and

  • processes of mineral accumulation

  • in a magma chamber


Andesites and Granites; predominantly

at subduction zones

  • Andesites; fractional crystallization versus contamination

  • Granites; fractional crystallization versus crustal melting

  • Understand Source, Path and

  • Evolution !!!
