Thin Section Lab on Fo'c's'le Deck
Overview
The Thin Section lab contains equipment for sample preparation of lithified and nonlithified materials for microscopy and microanalytical analysis (e.g. SEM-EDS). Thin section lab technicians are equipped to prepare core material in a wide variety of preparations, including but not limited to thin sections, polished thin sections, and grain mounts. Protocols for thin section creation vary based on material, and can be performed by hand (Buehler MetaServ 250) or through a largely automated process (Logitech LP-50 lapping machine).
