WebMay 6, 2024 · Stages of the igneous or magmatic cycle. 1. Early magmatic phase (early crystallization) from the fiery hot magma: 2. Liquid magmatic phase (main crystallization) 1500-600 degrees C: 3. Pegmatite phase (rest crystallization) 700-400 degrees C: The residual part of the magma, which is rich in fluxes, is known as the pegmatite stage. WebAug 1, 2007 · In this way, magmatic processes such as crystallization, recharge in a magma chamber, decompression during ascent, and convection in the magma chamber can be identified and the history of magmatic systems prior to eruption reconstructed.
As magmas crystallise, growing minerals respond to melt compositions and magmatic conditions via their textural characteristics, chemistry and style of compositional zoning (Figure 1A). Large crystals have traditionally been considered to grow in a tree-ring fashion, with concentric zones forming … See more The complex nature of subvolcanic plumbing systems reflects magma evolution by a succession of dynamic processes involving … See more Crystals act as chronometers that enable the reconstruction of magma transport and storage through time (Cooper and Kent, 2014; Costa et … See more TU drafted the first version of the text and figure, with input from DAN. All authors contributed to the final version of the article.
