(1986) Began independent career – California Institute of Technology. Our estimates of pressures and temperatures experienced by rocks during metamorphism are based on metamorphic reactions.. Mineral Reactions. There are two basic types of mineral reactions:. Continuous. These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base..
