Mineralogy, Raman spectroscopy and lattice parameter characterization of biotite with hexagonal structure from Borujerd hornfels and migmatites
Biotite is a common rock-forming mineral and accepts a variety of elements in its structure. The valuable information of crystallization conditions of the biotite mineral obtain on natural biotite composition. The biotite mineral is one of the main mineral phases of pelitic rocks which are formed in a wide range of geological conditions. In this research, microscopic mineralogy, Raman spectrosc...

متن کاملMinerals Their Constitution and Origin
Minerals: Their Constitution and Origin is an introduction to mineralogy for undergraduate and graduate students in the fields of geology, materials science, and environmental science. It has been designed as a textbook for use on a semester course and covers all aspects of mineralogy in a thoroughly modern and integrated way. The book is divided into five parts. Part I deals with the general c...
متن کاملMineralogical and geochemical investigations of chromite ores from ophiolite complexes of SE Iran in terms of chrome spinel composition
Ten chromite ores from ophiolite complexes in SE Iran were analyzed mineralogically by XRD, chemically by XRF, and mineral chemistry by EPMA. The identified paragenesis of silicate minerals of chromite ores with the X-ray diffraction is pronounced differently. It consists of secondary phases formed as serpentine, Cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...
متن کاملSilicates, Silicate Weathering, and Microbial Ecology
Mineralogy, microbial ecology, and mineral weathering in the subsurface are an intimately linked biogeochemical system. Although bacteria have been implicated indirectly in the accelerated weathering of minerals, it is not clear if this interaction is simply the coincidental result of microbial metabolism, or if it represents a speci c strategy offering the colonizing bacteria a competitive ec...
