Rocks contain many elements, ores, and minerals that require specific tools to extract.
The study of rocks and earth is called geology. Many different tools are used in geology to take rock samples, depending on where the sample is being taken. Rock sampling is carried out for scientific and commercial reasons. NASA took samples of rocks from the moon to assess the properties of lunar materials. Mineral companies take samples from potential mining sites to assess whether it will be profitable to mine.
Rock Hammer
Referred to as a rock hammer or geological pick, this tool is a versatile handheld device that can help the geologist extract rock samples. The tool is shaped like a hammer with a grip at one end. The other end is put to a dual purpose. One side of the head looks like a normal hammer. This is used for splitting open rocks to get at the minerals and ore inside. The other side of the head is tapered into a chisel. This is used to chip rocks away from a larger surface. The rock hammer is designed to save the geologist time by eliminating the need to change tools often. Rock hammers come made from different materials and in different sizes to deal with a variety of types of rock.
Auger
Rock samples do not always come from the surface of the ground. Samples are also taken from within the earth. To reach these samples, geologists need to drill a hole. An auger is a tool used to drill a short hole into either rock or earth. Handheld varieties are commonly used in ice fishing, and there are motorized varieties that are often used in commercial activities. The auger works by spinning like a corkscrew. This brings the minerals and earth to the surface following the rotating blades. This process is ideal for taking rock samples as the auger brings the material up to the surface. When using a motorized variety, however, it is necessary to use caution as lubrication and oil from the tool can spoil rock samples.
Containers
An essential tool of rock sampling is a proper container for placing the sample in. Most commonly used are clear plastic bags. These come in a range of sizes and the rock can be seen through the plastic for quick identification. Some rock samples however require to be transported and stored immersed in water. Immersing some rock samples in water will slow down the oxidization process. When stored in this way, the rock samples are placed into either glass or plastic boxes, which are rubber-sealed to prevent evaporation and contamination from outside elements.
