The duration and characteristics of magmatic differentiation …

A fundamental goal of igneous petrology is to quantify the durations required to produce evolved magmas following influx of basalt into the crust. However, in many cases, complex field relations and (or) the presence of a long-lived magmatic system make it difficult to assess how basaltic inputs relate to more evolved magmas, therefore precluding …

Trachyte

The feldspar phenocrysts may be large and sporadic, as in the celebrated Drachenfels trachyte, so that some care is required in using thin-sections to decide the type of feldspar present. In one-feldspar trachytes, phenocrysts are ternary anorthoclase feldspars, often cryptoperthitic. In sanidinites, partially resorbed plagioclase may occur as ...
