Abstract:

The proposed project intends to bring new data on the W-B mineralization in three skarn and deposits from Romania (Băiţa Bihor, Pietroasa and Budureasa). The research will be directed on the study of crystal chemistry, polytypism, thermal and infrared behavior of compounds in the scheelite – powellite, ludwigite – vonsenite and szaibelyite – sussexite series and on their weathering products (e.g., hydrotungstite, cuprotungstite, ferrotungstite for scheelite), as well as on the polytypism and crystal chemistry of associated magnesium-bearing species (e.g., brucite, periclase). Crystal-structure refinements, thermal and spectroscopic studies on these minerals are scarce in literature and could contribute to the understanding of the peculiar conditions for ore 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 B- and W-bearing 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 magnesian borates and scheelite deposits, as valuable tool for the rapid identification of these generally ignored species and (5) to refine new crystal structures, of great academic interest.

Abstract:

The importance of the geological knowledge in drawing up and relaunch the European Economic Area based on the principle of stable development is clearly defined by the programmatic documents of the European Commission such as Water Framework Directive (2000), Raw Materials Initiative (2008), Mining Waste Directive (2006), INSPIRE Directive (2007), Waste Framework Directive (2008), etc., with their counterparts in the National laws. The economical relaunch of our country, in accordance with the principle of the sustainable development, can be imagined only: (1) accepting the implementation of modern techniques of mineral processing to the huge potential of raw minerals; (2) redefining a large category of mining wastes (waste dumps, tailing ponds) as secondary resources fated to re-processing; (3) investigating the role of regolith in the soil geochemistry and assuring a correlation between these parameters and the best practices of crop growing. The proposed project aims at the use of the top geological knowledge to reinforce the research in the fields of raw materials processing, soil science applied to vegetal culture and exploration for critical raw materials. It was imagined as a bridge between the geological research and a part of the domains that benefit from its results (ore processing, waste recycling, grapevine cultivation, ore exploration). These goals are convergent with the attempt to find the best practices for reducing the environmental impact of some heavy metals and metalloids through a better monitoring and recovery, by choosing the best geochemical context as terroir element, by optimizing the prerequisites for critical raw material extraction, by an optimal storage of the geological databases flagship for economy. The project is served by a skilled team of experts, by the expertise, logistical facilities and the up-to-date equipment of the leader institution, as well as by a system of partnerships with institutions from abroad.

Abstract:

Diminution of residues and contaminants from the whole food chain is a great challenge for the world developed society. One of the most dangerous risk factors is represented by the agricultural insect pests and fungal diseases which destroy the crop plants in the field and post harvested yield in storage, generating huge economical losses every year. Mycotoxins produced by pathogenic fungi in cereal crops are transferred from field to storage, in feed, animal bodies and finally in food products obtained from these, such as eggs, milk and meat, producing human health disorders. Chemical means (insecticidal fungicidal products and storage fumigants)from risk management programs implemented in agricultural practice to reduce storage insect populations and mycotoxins transfer from storage to animal diet were not able to completely destroy pests or mycotoxigenic fungi, nor in field or storage. Technical solution proposed by the project is an innovative approach of treatment in the sequence of food chain from storage to animal body grown in farm, with ecological products obtained from bioactive diatomaceous earth and essential oils from renewable vegetal sources with insecto-fungicidal properties. Project consortium consists of three complementary Research and Development Institutions covering the multidisciplinary thematic domain of the project (mineralogy, plant protection and chemistry of bioresources for bioproducts obtanation) and an agrotechnical farm as a small enterprise and co-financier. Experienced research specialists of the implementation team of the project will select the best bioactive diatomaceous earth from Romanian local deposits, the most efficacy natural principles from essential oils and the best recipes to obtain modern formulations of ecological products (encapsulated slow release granules and tablets). To attain such ambitious objectives, the mineralogists from RGI will collect, identify, characterize and select the most appropriate mineral constituent for the ecological formulations and the NIRDCP Partner will develop laboratory technologies for obtaining vegetal bioactive principles and formulation of original ecological products for grain storage treatment and veterinary feed supplement to be patented and transferred for a larger scale micropilot production. Raw materials, intermediates and final products will be subject to biological screening for selection of the most effective against insects and mycotoxigenic fungi infesting stored grains, in controlled conditions by RDIPP and in production conditions of storage by the farm Agrotehnic. Patented procedure of use and a new guide of good practices in the management of contamination risk in storehouses will be provided. The mycotoxin contamination and the diminution degree of the mycotoxin concentration on stored grains as an effect of the treatment with the ecological product will be quantified by chromatographic, biochemical or electrochemical methods. For antimycotoxin antidote efficacy of veterinary feed supplements, an accredited institution for biological evaluation services on model animals will be subcontracted. Project results which are not object of intellectual or industrial property rights will be disseminated on a wide scale at national and international scientific events. Agrotehnic farm has a great potential for cereal production and proper grain storage, a guaranty for the implementation of the project results and good perspective for agro-technological development, with interest and excellent chances to gain a better position on the national and international market with new agro-veterinary products, cheaper, easy available for farmers, rapidly biodegradable, non-toxic for mammalians, eco-friendly alternatives to synthetic insecticides and fungicides.

Abstract:

The occurrences of high-temperature calcic skarns are relatively rare. Worldwide, over thirty records of such rocks were reported, from which four are located in Romania: Oraviţa, Ciclova, Măgureaua Vaţei and Cornet Hill. These skarns are basically composed by carbonates and silicates that can be easily related to the CaO-SiO2-H2O-Al2O3 system, usually described as C-S-H-A phases by the cement researchers. The Portland cements and clinkers basically contain the same phases, whose lower crystallinities preclude accurate studies. Natural systems such as the in-situ self-combusted carbonatic formations (Hatrurim in Israel and Maquarin in Jordan) were used for studies on the hydration of the calcium silicates and described as natural cements, but the conditions offered for study by the calcic high-temperature skarns are much better. These skarns are usually barren and offer the best conditions for the study of the hydration parageneses developped on the (carbonate- and sulfate-bearing) calcium silicates. The project proposes a minute study of the crystal chemistry and crystallography of the high-temperature, hydrothermal and weathering mineral parageneses from the four Romanian occurrences of high-temperature skarns, which will be of great interest for the cement and concrete studies. As fundamental research work, it will enlarge the knowledge on the mineralogy of the high-temperature skarns, which have one of the most important potential for the discovery of new mineral species
