Today features a grain mount of epidote which was collected on a fieldtrip to Spain earlier this year. A grain mount is a quick and easy alternative to making a thin section. Particles from a sample are mounted onto a glass slide with epoxy and covered with a cover slip; this can then be viewed with a petrographic microscope. When I collected the specimen, I was unsure of what the mineral was. Luckily, Ruth Siddall was able to identify the mineral and make the grain mount.
