Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much 'heavier' than expected for their size. Because it melts at a relatively low temperature and is so ...

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Sandstone. 2.2–2.8. Shale. 2.4–2.8. Slate. 2.7–2.8. As you can see, rocks of the same type can have a range of densities. This is partly due to different rocks of the same type containing different proportions of minerals. Granite, for example, can have a quartz content anywhere between 20% and 60%.

The Streak Test: Marks, known as "streaks," are produced by scraping mineral specimens across unglazed porcelain plates. On the left, a specimen of pyrite has produced a black streak. On the right, a specimen of rhodochrosite has produced a white streak. Many minerals produce a white streak, and some geologists prefer using a black streak plate ...

Small ores can be found scattered around on the surface of the ground. These are samples of what ore veins are located within 35 blocks underneath the soil, so they're somewhat important. In the majority of cases, it is a sample of a vein in the top layer of stone. However, in areas where the top layer is thin enough, the vein may be located in the …
