SAMPLING IN GEOLOGY

 · • Channel samples have the advantage over RC samples in that the material can be geologically logged prior to excavation. 10. • Where the material to be sampled is close to the surface, trenches are excavated to gain access to the material and samples are taken either as channel samples within the trenches or as selected samples of the excavated material.

How a Laboratory Crusher Works

 · Geological samples are first treated in a laboratory crusher, and that makes it possible for them to be spectroscopically analyzed, so that the material properties of each sample could be discerned. The samples can also be analyzed as an extension of their wider environment, which allows researchers to extrapolate accurate data about a given ecological area having minimal invasiveness.
