The Size of Crystals in Igneous Rocks Is Generally a Function

question 84

Essay

The size of crystals in igneous rocks is generally a function of the rate of cooling. However, within the same rock, crystal size does not necessarily reflect the order of crystallization for individual minerals. Without using Bowen's Reaction Series, how might you determine the order of crystallization of minerals in an individual rock sample? (Hint: Think about the texture.)
