Rocks and Minerals Geology (U.S. National Park Service)

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

Re PHREEQCi USGS

May 29, 2001 Having used PHREEQCi for a while for inverse modelling calculations, I have been trying to add my own phases, i.e. (i) different mineral stoichiometry, and (ii) different phase reaction steps. Although I am probably incorrect, I have wanted to do this because I wanted to simulate particular reactions, not just to get an idea of the final mole
