Classification of Common Rocks
Igneous - information can be quantified for: crystal shape; grain size; proportion of crystallline versus glass components; oscillatory, normal and reverse zoning in isomorphic minerals (feldpar, olivine, pyroxene, tourmaline etc); exsoution, intergrowth, and reaction textures. This information leads to improved interpretations of the cooling history, order of crystallization, and viscosity modelling of igneous rocks and their parental magmas.
Sedimentary - our automated mineralogy images are used to investigate depositional environment, as well as the diagenetic components, of all types of terrigenous, organic, bioclastic, and chemically precipitated sedimentary rocks.
Metamorphic - rocks formed under metamorphic conditions are typically the result of a complex sequence of events and processes - normally involving extreme heat, pressure, and various geo-fluids - all operating over extended periods of geological time. The new minerals, their textures and reactions can all be seen in automated mineralogy images, leading to a better understanding of the history of the rock.
Extra-terrestrial - recent studies have shown the power of automated mineralogy images to provide new insights into the complex textures and phase relations of meteorites, lunar material, and other extra-terrestrial samples.
