If samples are submitted to a petrographic laboratory, the petrographic classification generally will coincide with the classification according to Travis. The petrographic igneous rock classifications are somewhat more precise and include specialty rock types based upon mineral com-position, texture, and occurrence. For example, a

2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.
Modification of the sample material through cutting, drilling or grinding using various saws or drilling tools are carried out to adjust the sample material for further processing or analysis, e.g. for thin section puck production, epoxy mount finishing, crushing or adjustment of irregular sample sizes. Equipment: Rock saws with diamond blades:
Crushers include offers jaw crushers, hammermills, cone crushers, and roll crusher options, each with multiple models, and designed for performance on harder materials such as ores, minerals, coal, and rock. Pulverizers efficiently reduce aggregate, mineral or coal sample particle sizes using grinding plates, hammermills, or centrifugal impact.
Some general considerations during sample preparation are to minimize sample losses and to prevent contamination. Possible mechanisms for sample loss during preparation steps are discussed in Section 12.2.1, and the contamination of samples from sources in the laboratory is discussed in Section 12.2.2.
"The unaltered rock below the surface may hold important clues to the history of the area," Iona Brockie, a sampling engineer at NASA's Jet Propulsion Laboratory, wrote in a 2021 blog post. Ultimately, grinding away at rocks will lead scientists to the most promising, or interesting, samples to bring back home.
