How to make rock thin sections, without much equipment

2007-3-18  longer than a softer sedimentary or metamorphic rock. I mostly make thin sections of basalt, which is the dark gray type of lava. It is fine-grained with little or no quartz, so basalt grinds down quickly and evenly. To finish, cement a cover slip onto the rock, being careful to once again make the cement free of bubbles with the warming plate.

Preparing a Thin Section of a Rock - National Petrographic

A thin section of rock is prepared so mineralogists and petrologists can identify, study, and analyze the material more closely. This is known as thin section preparation. Using this method, you can classify minerals, identify problems in quarries or structures, examine mineral potential in geological environments, and identify the geographical source of archaeological artifacts.

2.4 Procedure: How to Make a Thin Section Analytical ...

The general procedure for creating thin sections has remained nearly the same since the modern version was created nearly 200 years ago. In this module, we review two examples of modern thin section making procedures. If you have read the history of thin section preparation (section 2.3), you should be already familiar with most of the process.
