Abstract
A collection of 123 nephrolyths extracted from patients living in the territory of the South and Middle Urals has been studied. The in-depth phase-morphological description of the 6 most widespread mineralogical nephrolyth types is given. The majority of the specimens studied represent zonal matter characterized by the particular sequence of alternating or changing mineral zones. The information on the quantitative relationship between mineral phases in the concrements is for the first time presented in the form of conventional formulae similar to the crystallochemical formulae of minerals. An integrated application of the modern analytical methods (X-ray analysis, IR spectroscopy, scanning electron microscopy, and two X-ray spectrum microanalysis methods, namely, energy dispersive and electron probe microanalysis) has made it possible to obtain radically new information about the peculiarities of internal structure, micromorphology and chemical composition of nephrolyths.
