What is Bowen's reaction series about?

Answer 1

The purpose of Bowen's Reaction Series is to visually represent the conditions under which different igneous rocks form in an organized way that is easy for the viewer to understand. Bowen's Reaction Series is important to geologists because it helps them understand the order in which specific minerals were created.

Answer 2

Bowen's reaction principle A concept, first propounded in 1928 by NormanBowen, which explains how minerals can respond to the changing equilibrium conditions when a magma is cooled, by either a continuous, diffusion-controlled exchange of elements with the magma or discontinuous melting of the mineral. In a continuous exchange or reaction, solid-solution minerals such as feldsparadjust their composition during cooling by a continuous diffusion of elements between magma and mineral, whilst in a discontinuous reaction, minerals such as olivine undergo melting at a specific temperature during cooling (the peritectic point) at the same time as a new mineral in equilibrium with the magma begins to crystallize (in this case pyroxene). Bowen suggested a series of these reactions that might take place during the cooling of a tholeiitic basalt magma, the so-called Bowen's reaction series, but pointed out that the series was a simplification of very complex reactions and could be misleading if taken at face value. The specific reaction series for tholeiitic magmas was never intended to become a general reaction series for all magmas.

Answer 3

the relationship between cooling magma and the formation of minerals that make up igneous rocks

Answer 4

The Bowen Reaction Series is a chemical model that helps us to understand the origin and variety of igneous rocks that we find spread around the Earth.
