Thin Section Rock Grinder

PowerPoint Presentation - GeoHub Liverpool

Rock thin sections are slices of rock glued onto microscope slides and polished until they are about 30μm thick (about the thickness of human hair). The microscope used to study minerals in rock thin sections. The main feature of a polarizing light microscope is that it has two polarising filters called the polariser and analyser. The polariser (mounted below the thin section) is adjusted so

Robotic Instrument for Grinding Rocks Into Thin

We have developed a rock grinding and polishing mechanism for in situ planetary exploration based on abrasive disks, called Grinding Rocks Into Thin Sections (GRITS). Performance characteristics and design considerations of GRITS are presented. GRITS was developed as part of a broader effort to develop an in situ automated rock thin section (ISARTS) instrument.

A motorized grinder for making soil thin

01-04-1984· A motorized grinder for making soil thin sections. Geoderma, 32: 335--337. A small hand-held device is described which enables an operator to grind soil thin sec- tions very rapidly as compared to conventional hand grinding. The apparatus is relatively inexpensive and easy to construct as it comprises only a simple motorized grinder and grit

Microscopy). Thin sections are an essential part of geology, and especially important for studying rocks from other planets, such as the Dar al Gani 476 meteorite from Mars. Here is how a thin section is made: A chip is broken or cut from the rock. One side of the rock chip is flattened (by sawing and grinding) and is glued to
