Explore how rocks change under pressure and time as you follow detailed observations of peridotite and serpentine from the Cordilleras.
This volume presents careful descriptions and classifications of lithologic varieties, with clear illustrations and notes on texture, alteration, and mineral changes.
The text guides readers through early and later stages of alteration, showing how olivine, enstatite, and related minerals transform under serpentinization. It highlights how groundmass and mineral rims evolve, and it discusses differing opinions on origin and structure, all grounded in specimen study and photographic plates.
- Clear, plate‑level descriptions of peridotite and related rocks, including lherzolite and picrite varieties
- Descriptions of serpentine formation, iron-ore dust, and pseudomorphs after olivine
- Notes on structural interpretation, alteration patterns, and microscopic textures
Ideal for readers of historical geology and mineralogy, and for anyone seeking a window into classic rock classification work.
