This course on Pyroxene Hornfels Facies in Petrology aims to teach students about the characteristic mineral features, mineralogical assemblages, and important reactions associated with this specific metamorphic facies. By the end of the course, students will be able to identify the Pyroxene Hornfels Facies and understand the physical conditions of metamorphism. The course covers topics such as the presence of wollastonite in calcic assemblages, the coexistence of cordierite and andalusite/sillimanite with other minerals, and the unique characteristics of almandine garnet in this facies. The teaching method involves lectures and discussions led by Dr. Harel Thomas, a subject expert in Petrology. This course is designed for undergraduate and postgraduate students of Geology who are interested in gaining a deeper understanding of metamorphic processes and mineral assemblages in Pyroxene Hornfels Facies.

Muscovite + Quartz are no more stable and cordierite and andalusite/Sillimanite coexist with K-feldspar, biotite and almandine garnet are of restricted occurrence.
PYROXENE-HORNFELS FACIES CHARACTERISTIC MINERAL FEATURES
Presence of wollastonite in calcic assemblages and of calcite-forsterite-periclase (MgO) and calcite-forsterite - diopside in silica-poor dolomitic marbles. 5 . Almandine garnet when present has a high Fe2+/Mg ratio compared with that of granulite facies assemblages. The typical magnesian phase is cordierite.
