Answer 1

As magma cools and crystallizes, minerals form in predictable patterns in a process known as Bowen's reaction series, named after Norman Levi Bowen and his work in the domain of the processes of cooling magmas. The Bowen's reaction series is the sequence in which minerals crystallize from a magma, which helps geologists to understand the order in which specific minerals were created.
