There are many pieces made of siliciclastic sedimentary raw material. Their fragmentary condition makes it possible to examine them by slightly destructive methods, such HMA (heavy mineral analysis), which was developed primarily for siliciclastic rocks. Until now, ‘sensu stricto’ (s.str) heavy mineral analysis has not yet been carried out for ground stone tools, neither at the national nor at the international level. By comparing the heavy mineral compositions of the stone tools and their potential raw materials with the help of a newly developed HM descriptive system (including rutile, zircon, tourmaline, apatite and titanite), it is possible to determine the provenance of these archaeological materials. From the Neolithic tell of Gorzsa, 109 red sandstone macrolithic stone tools are known. These were separated into four, different types (‘Red–1’ – ‘Red–4’), based on the macroscopic and microscopic analysis. 11 fragments were chosen for HMA analysis. In addition, red-coloured sandstones from different geological occurrences of the Carpathian-Pannonian Basin (22 pieces) were also investigated. Based on the heavy mineral analysis, all raw material types of the stone tools could be originated from the Maros River and the Apuseni Mountains (Transylvania). However, the previously determined potential sources (Permotriassic and Miocene sequences from the Mecsek Mountains, Balaton Highlands, pebbles from the Danube River, and Papuk Mountains) cannot be excluded with absolute certainty from the possible raw materials.

The well-protected fortification played a significant infrastructural role, due to the fact that the lake could be crossed here along a main north-south road of Pannonia. Archaeological excavations started in 2009 had the primary goal to clarify the location, floor plan and dating of individual buildings (nos. 24, 25 and 27). Based on petrographic, geochemical, and engineering geological investigations of mortars used in the constructions, we were able to gain insight into the possibilities of answering certain archaeological questions with geoarchaeometric methods. Mortar samples were systematically collected from the different locations representing the functions and construction phases. Based on the archaeological research three chronological groups (I.-III: end of 3rd c. to early 7th c. AD) were distinguished; two of them belong to the late Roman Period (I.-II.) and one (III.) to the Migration Period. The aggregates of the mortars were analyzed by polarized light microscopy and thermoanalytical method. The chemical examination of the binder was carried out by scanning electron microscopy. Additionally, water absorption, density and compressive strength of the mortars were also determined. Based on the results, we can conclude that the mortars of all three periods are of air lime nature containing Mg and Si impurities and both the binders and additives were produced using local raw materials rich in dolomite components. The higher compressive strength values of the mortars of the 3rd period (late 5th to early 7th c. AD) are probably due to the slightly different composition of the binder, or they can also be explained by the static role of the selected pillars. © by the author(s) LA - English DB - MTMT ER - TY - JOUR AU - Gyollai, Ildikó AU - Biri, Sándor AU - Juhász, Zoltán AU - Király, Csilla AU - Rácz, Richárd Péter AU - Rezes, Dániel AU - Sulik, Béla AU - Szabó, Máté Zoltán AU - Szalai, Zoltán AU - Szávai, P AU - Szklenár, Tamás AU - Kereszturi, Ákos TI - Raman–Infrared Spectral Correlation of an Artificially Space-Weathered Carbonaceous Chondrite Meteorite JF - MINERALS J2 - MINERALS-BASEL VL - 14 PY - 2024 IS - 3 SN - 2075-163X DO - 10.3390/min14030288 UR - https://m2.mtmt.hu/api/publication/34762210 ID - 34762210 AB - Raman and infrared measurements of the same locations were conducted on a northwest African (NWA) 10580 CO3 meteorite sample, before and after three proton irradiations (1 keV ion energy using 1011, 1014, and 1017 ion/cm2 fluent values), to simulate space weathering effects. In the case of Raman spectroscopy, both FWHM and peak positions of the major olivine and pyroxene bands changed after the irradiation, and the minor bands disappeared. In the FTIR spectra, the minor bands of olivine and pyroxene also disappeared; meanwhile, major IR bands of pyroxene remained visible, demonstrating both positive and negative peak shifts, and the olivines were characterised only by negative peak shifts. The olivines were characterised by negative FWHM changes for major bands, but positive FWHM changes for minor bands. The pyroxenes were characterised by elevated FWHM changes for minor bands after the irradiation. The disappearance of minor bands both of IR and Raman spectra indicates the amorphization of minerals. The negative peak shift in IR spectra indicates Mg loss for olivine and pyroxene, in agreement with the literature. The Raman spectra are characterised by positive peak shift and positive FWHM changes; the IR spectra are characterised by a negative peak shift. The Mg loss, which was detected by negative peak shifts of FTIR bands, may be caused by distortion of the crystal structure, which could be detected by a positive peak shift in Raman spectra. This joint observation and interpretation has not been formulated in the literature, but indicates further possibilities in the confirmation of mineral changes by different instruments. Shock alteration-based observations by other researchers could be used as a reference for irradiation experiments as irradiation makes a similar structural alteration, like a low-grade shock metamorphism.

Due to their excellent water tightness and strength, cementitious materials are used to build WWTPs. However, the performance of these materials is affected by aggressive environments. There are few in situ experiments in the literature regarding the deterioration of cementitious materials in WWTPs. This paper investigates their deterioration mechanisms in a sewage pumping station and a sand-trap structure of a WWTP. In situ experiment was conducted by exposing cement specimens in both locations for 1, 2, 3 and 7 months. The physical and morphological changes of the specimens were examined using stereo microscopy and scanning electron microscopy, whereas the mineralogical/solid phase changes were examined using X-ray diffraction. The results showed that the specimens from the pumping station formed colored surface products, which were confirmed to be secondary minerals (i.e., gypsum and ettringite), whereas there were no colored surface products in the sand-trap structure. The results demonstrated that cementitious materials subjected to wastewater vapors (in a pumping station) had higher deterioration effects than those subjected to wastewater liquid (in a sand-trap structure), suggesting that the wastewater vapors are more aggressive toward cementitious materials than wastewater liquids.
