Determine if your specimen is an artifact, a fossil, a rock, or a mineral. Let's start with the basics. The first thing to do is to determine if your specimen is an artifact, a fossil, a rock, or a mineral. The Campbell Geology Museum does not offer identification of potential meteorites. Figure 3.6.11. The formation of evaporite sedimentary rocks. As a closed off body of water, such as a lake, evaporates over time, minerals will precipitate in the following order: calcite, gypsum, halite. Rock salt is sometimes confused with another clear, single-mineral sedimentary rock called.Teaching and Learning Focus In the last investigation, students learned about body fossils, fossils that are the actual organism or some part of it or the imprint of the organism or some part of it.
