Bowen’s Reaction Series
Bowen's reaction series is based on observations and experiments of natural rocks, the crystallization sequence of typical basaltic magma change as they cool. It is a sorting tool according to the temperature at which they crystallize common magmatic silicate minerals.

Unconformities
An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.
