He experimented in the early 1900s with powdered rock material that was heated until it melted and then allowed to cool to a target temperature whereupon he observed the types of minerals that formed in the rocks produced. He repeated this process with progressively cooler temperatures and the results he obtained led him to formulate his reaction series which is still accepted today as thidealized progression of minerals produced by cooling magma . Based upon Bowen's work, one can infer from the minerals present in a rock the relative conditions under which the material had formed. The series is broken into two branches, thecontinuous and the discontinuous . The branch on the right is the continuous. The minerals at the top are first to crystallize and
