Magma mixing is the mixing of two or more magmas or magma batches to form a hybrid magma. The resulting magma commonly inherits intermediate properties of the two parent magmas.
While this definition makes the process of magma mixing sound straight forward, the occurrence of mixed rocks, where for example both rhyolite and basalt are found within the same rock mass, suggest a more complex process.
Within these pages we define, discuss the controlling factors, provide examples and show a laboratory simulation (MPEG movie, 1.4 Meg) of magma mixing. We suggest that you watch the movie, then read through these pages in the order below, and then watch the movie again!!!
