Making Rock Thin Sections

Thin Section Introduction

Rock specimens are often friable and brittle by nature therefore thin section preparation requires meticulous, reliable slabbing, grinding, lapping and polishing machines. thin section samples: Typical rectangular thin sections are 26 mm x 46 mm, although Vinci equipment permits size customization.

Different Types Of Thin Sections

When a laboratory prepares a rock, mineral, fossil, concrete, or various other samples for analysis by cutting a slender section, this is known as a thin section.Usually, the laboratory uses a diamond saw to cut a section 0.03 mm thick, though it can create thinner or thicker sections as necessary.

Thin Section Cookbook

The mounted billet is next trimmed on the Petro-Thin machine to remove excess rock. Since most of the billet can be trimmed off intact, it can be retained for making additional thin sections. The slice left mounted on the thin section should be less than 150 microns thick. V. Grinding the Thin Section

Studying Rocks In Thin Section

To do this, they make thin sections slices of rock so thin that light actually passes through them! Geologists then use microscopes to analyze these sections. The magnified view allows scientists to see minerals that are not large enough to view in the hand-held sample, and to
