Wide range of calcifications as biogeneous concretions have been studied by the X-ray microtomography and X-ray diffraction phase analysis using mineralogical approach: cfacifications, gallastones and salivary stones, calcifications. Internal morphology and phase composition were studied. The results of laboratory tests on their mineral composition are presented. The biolithos concrements morphology and mineral structure were investigated on the mineralogical point of view.
