WebThis collection of virtual thin sections is the result of a collaboration between earth scientists at Leeds University and The Open University. The collection consists of 20 slides from the Leeds teaching collection, including igneous, metamorphic and sedimentary rocks. Kyanite occurs in biotite gneiss, mica schist, and hornfels, which are metamorphic rocks formed at high pressure during regional metamorphism of a protolith which is rich in aluminium (a pelitic protolith). Kyanite is also occasionally found in granite and pegmatites and associated quartz veins, and is infrequently found in eclogites. It occurs as detrital grains in sedimentary rocks, although it tends to …
