List of publications related to the project:
The proposed project aims to provide new data on W, Mo, B, Mg, Te, Bi, and Sb mineralizations—metals classified as critical high-tech raw materials for the European Union—found in a series of skarn deposits in Romania (Mraconia, Ciclova, Oraviţa, Ocna de Fier, Dognecea, Pietroasa, Budureasa, Cacova Ierii, Masca Băişoara, and Băiţa Bihor). Research will focus on the crystal-chemical, crystallographic, polytypic, thermal, and IR behavior of minerals belonging to the tungstate, magnesium borate, sulfide, sulfosalt, and magnesium oxide groups. Re-Os dating of molybdenite will help establish the timing of metallogenesis. Associated calcium silicates and carbonates will also be investigated. Structural refinements and thermal and spectrometric analyses of minerals in these groups are often scarce in the literature, and this lack of information hinders mineral processing. The project’s main objectives are: (1) to characterize the deposits in terms of mineralogy, geochemistry, and the crystallography of their constituent minerals; (2) to determine the crystallographic and physical properties of W, Mo, B, Mg, Te, Bi, and Sb compounds and correlate them with their chemical composition, in order to facilitate the development of processing technologies; and (3) to compare the crystal chemistry, physical properties, and crystallography of the analyzed compounds with the characteristics of analogous minerals available in collections. (4) development of specific analytical suites (electron microscopy, X-ray diffraction, IR absorption spectrometry) for the rapid diagnosis and identification of alteration phases in scheelite, borate, brucite, and sulfosalt deposits, which are generally overlooked; (5) determination of the crystal structure of new minerals of significant academic interest; (6) development of a genetic model for each deposit; and (7) provision of logistical support for ongoing Master’s and doctoral studies and for international cooperation activities.
Title: Resource geology as a basic tool for sustainable development according to the European standards
The proposed project intends to bring new data on the high-tech and critical for E.U. W- Mo- B- Mg- Te- Bi- and Sb-bearing mineralizations in a series of skarn deposits from Romania (Mraconia, Ciclova, Oraviţa, Ocna de Fier, Dognecea, Pietroasa, Budureasa, Cacova Ierii, Masca Baisoara and Baiţa Bihor). The research will be directed toward the study of crystal chemistry, polytypism, thermal and infrared behavior of compounds in the tungstates, magnesian borates, sulfides, sulfosalts and magnesian oxides. Re-Os ages on molybdenite will contribute to the temporal assignment of the ore depositional event. The associated calc-silicates and carbonates will be also investigated. Crystal-structure refinements, thermal and spectroscopic studies on the target minerals are scarce in literature, the lack of information being an impediment for the mineral processing. The main project goals are: (1) to characterize the host deposits from mineralogical, geochemical and crystallographic points of view; (2) to emphasize the crystallographic and physical properties of the target minerals and to compare them with the crystal chemistry in order to facilitate the processing technologies; (3) to compare the crystal chemistry, physical constants and crystallography of the analyzed compounds with the characteristics of similar phases in available collections; (4) to develop specific analytical packages (e.g., scanning electron microscopy, X-ray diffraction, FTIR) for rapid diagnosis of the weathering phases in scheelite, borate, sulfides, sulfosalts, magnesian oxides deposits, as valuable tool for the rapid identification of these generally ignored species; (5) to refine new crystal structures, of great academic interest; (6) to propose a genetic model for each individual ore deposit, and (7) to assure the logistical support for on-going M.Sc. and Ph.D. works and for international cooperative research actions.
