In the field of geology, the Bowen reaction bundle is the work of petrologist Norman L. Bowen who sums up, based on experiments and observations of natural rocks, a typical crystallization of basaltic magical crystals undergoing fractional crystallisation (ie crystallization in which the crystals are formed early removed from the magma by the precipitation of the crystals, say, leaving a slightly different composition fluid.Construction reaction Bowen is able to explain why certain types of minerals can be found together while others are hardly ever attributed to each other.He experimented in the early 1900s with powdered rock material which is heated to melt and then allowed to cool to the target temperature where he observes the type of minerals formed on the rocks produced.He repeated this process with increasingly cold temperatures and the results he obtained led him to formulate the reaction sequences that are still accepted today as the ideal development minerals produced o leh cooling of basaltic magma undergoing fractional crystallization. Based on the work Bowen, one can deduce from the minerals in the stone, the relative conditions in which the material is formed.

Description
The series is split into two branches, continuous and disconnected. The branch on the right is continuous. The minerals at the top of the illustration (ruled out) are first to crystallize and so the temperature gradient can be read from high to low with high temperature minerals at the top and low temperatures at the bottom. Since the Earth's surface is a low-temperature environment compared to the rock formation zone, the graph also easily demonstrates mineral stability with the most stable bottom and the fastest becoming weather, known as the Goldich dissolution series. This is because the most stable mineral in the condition closest to the one below it has formed. Simply put, high-temperature minerals, the first to crystallize in magma masses, are at least stable on Earth's surface and fastest for the weather because their surface is most distinct from the conditions in which they were created. On the other hand, low temperature minerals are much more stable because the conditions on the surface are much more similar to the conditions under which they are formed.
