This is a rather rare garnet, bright green in color, usually found as small crystals associated with chromite in peridotite, serpentinite, and kimberlites. It is found in crystalline marbles and schists in …

Habit/Form: Garnets commonly occur as euhedral to subhedral dodecahedral {110} or trapezohedral {112} crystalss, which in thin section yield six- or eight-sided cross sections.

Different types of garnet may be translucent or slightly opaque, leading to variable lusters. High relief in thin section. Color in thin section is a pale version of the hand sample color, and is often more lightly …

Colors are pale in thin section, ranging from transparent to pale pink to yellowish (grossular), brownish (andradite), and green (ugrandite garnets). Compared to spinel, garnet shows much paler colors.

A look at garnet with an optical microscope with a focus on identifiable optical properties.

He curated a collection of 42,000 rock specimens, as well as numerous thin sections, from the 1880s up to his death in 1939: these specimens form the core of what is now known as the Harker Collection.

This thin section contains a sea of fine grained muscovite (with some minor graphite) that includes two large garnets. The garnets are euhedral, typcial of low- to medium-grade metamorphic rocks such as …

This 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 …

This activity will help you to recognise garnet in hand specimen and thin section. For this activity you will require the Digital Kit and the Virtual Microscope.
