There are metabasite exposures inside ophiolitic belt of northwest Sabzevar that metamorphosed under high pressure granulite facies. On the basis of mineralogical paragenesis, reactional textures between different mineralogical assemblages, textural and mineralogical relations between inclusion and porphyroblast and stability fields of different mineralogical assemblages, five stages of evoluti...
The International Mineralogical Association and UNESCO celebrates 2022—the Year of Mineralogy [...]
in this study, we focused on detailed studies on micromorphological and mineralogical properties of three types of peat and swamp, to compare these different ecological area together. to achieve this goal, samples from a highland peat swamp (ghaleh-ghafeh ps), a peat swamp forest (suteh psf) and a costal swamp (galougah cs) in golestan province, north of iran have been considered. these studies...
The Cretaceous Western Interior Seaway Drilling Project was begun in 1991 under the auspices of the U.S. Continental Scientific Drilling Program. It was intended to be a multidisciplinary study of Cretaceous carbonate and silicicl.tic rocks in cores from bore holes along a transect across the Cretaceous Western Interior Seaway. The study focuses on middle Cretaceous (Cenomanian to Campanian) st...
The paper studies the effect of additives such as calcite, dolomite and sodium chloride on the mineralogical–textural and physical–mechanical behaviour of solid bricks destined for use as new materials in the restoration of historic buildings. The behavioural differences between specimens with and without carbonates can be explained by the different evolution of texture and mineralogical compos...
Majority of the process mineralogical studies can be described as optimization problems where conditions for the best economic and most resource efficient processing are sought. For solving such a problem the raw process mineralogical data is not enough; optimal solution can be found only through modelling and simulation. Automated mineralogy provides accurate and detailed information on proces...

Classification is broadly used in a range of exploration technologies. This paper will summarize standard classification methods and provide a new hybrid method for classifying spectra used in mapping mineralogy with hyperspectral remote sensing data. Classification methods commonly employed do not allow the user specifically to identify key features that give confidence as to the quality of th...
