Preparing Samples. High quality geochronology begins at the outcrop where care must be taken to avoid weathered or altered rocks. The amount of sample needed depends on a variety of factors (1) how old the rocks are, (2) are there potassium-rich minerals like sanidine, biotite, or amphibole and if so, what is the modal %, (3) for lava flows, is the groundmass texture holocrystalline, rather ...

This exciting product range offers you the latest in technology and functional design to provide high levels of performance in preparation of minerological samples and thin section specimens.
Our Thin Section Laboratory is currently closed but will remain open for rock saw usage if you are already trained. For the remainder of this summer 2021, recent MS graduate, Kelsey Livingston (klivingstonmymail.mines.edu), will continue to help manage our Thin Section Lab on a part-time basis, keeping access available to the rock saws and other peripherals, with oversight.
Metallurgical Sample Preparation Microscopy and SEM Samples. Precision Metallurgical Sample Preparation, also called Metallographic Specimen Preparation, is a key step in performing reliable metallurgical testing.This type of testing often involves evaluating the microstructure of materials through the use of optical magnification or scanning electron microscopy (SEM).
A rock sample belongs to a greater geologic formation, which likely has published information discussing its origin and evolution. Rock sampling is a cheap and effective way to characterize many important properties of a geothermal resource. Rock properties define a geothermal resource and are the most important factors which can yield a power ...
Acid digestion of soils and sludges is one example of solid sample preparation for ICP-OES. The analysis of soils is needed in order to monitor the land used for crop growth. Nutrient levels and the presence of toxic elements are monitored so that crop growth can be monitored and
