Summary:Title screen
The mineral and chemical composition of graphite and graphite-bearing marbles from the Vacha, Ardino–Nedelino, and Chernichevo–Boturche areas was studied. The minerals identified by X-ray diffraction in different marble samples are calcite, dolomite, pargasite, chondrodite, quartz, and graphite. The presence of accessory minerals, such as apatite, rutile, zircon, Fe sulfides, Ag-Pb-Sb, Pb-Bi, Ag-Sb phases, etc was confirmed by LA-ICP-MS. Among the analyzed 58 elements in the marbles, only Mo, Sr, Bi, Pt, Ag, and Sb have contents that exceed at least twice the Clarke values for metamorphosed carbonate rocks. The graphite concentrate contains micron-sized phases of Mo-S, Cu, Fe, and others. The contents of 26 elements were measured by INAA in graphite. Uranium, As, Zn, Th, Sb, and Sm have several times higher concentrations compared to the content in the original graphite-bearing marble
