The Palaeolithic site from Cremenea – Poieniţă, Covasna Department. An attempt towards a techno-typological and cultural reassessment

The researches previously carried out in the Paleolithic site from Cremenea – Poieni " # offered a large lithic assemblage qualified as Aurignacian and a much smaller one, thought as belonging to the Gravettian. The paper here presents a techno-typological analysis performed on the lithic collection found in the History Museum from Bra ov. Unfortunately, the collection lacks an important part of the initial Aurignacian inventory. Consequently, the outcome of the techno-typological analysis neither confirms nor rejects the cultural framing already proposed ; it only succeeds in raising some doubts regarding the Aurignacian designation.Mărgărit Dan, Niţă Loredana.

Radon Measurements and Radon Remediationin Băiţa-Ştei Pronearea

Băiţa-Ştei was the largest uranium reserve in Romania with estimated reserves of 450,000 tons of high grade metal. It was a large open pit mine in the northwest of Romania (West Carpathian Mountains), situated at 123 km south-east of Oradea, the capital of Bihor County. The transport during the time of sediment by Crişul Băiţa water course increased the uranium and radium content in the river meadow. The building material from Crişul Băiţariver bed (stone, gravel, sand) was used as construction material for the houses. In addition, some people living on this valley and surroundings after the opening exploitation used as building material the uranium waste from this mine. Preliminary indoor radon measurement (grab samples) in the villages situated on the route of ore transport (BăiţaPlai -Ştei) shown high radon concentrations, until 5000 Bq m−3. The new result obtained in this work in springer season 252 Bq m−3 is comparable with the annual means of 241 Bq m−3 and 229 Bq m−3 respectively, previously obtained, but more than twice times higher than the average value of 126 Bq m−3, computed for Romania. About 3000 of etched CR-39 track detectors were used followed by a selection of 20 houses proposed for remediation where a systematic investigation regarding radon sources was performed. The measured indoor radon concentration in the surveyed buildings ranged from 40 to 4000 Bq m−3. For experimental research, a representative pilot house was chosen. This house represents an example of a typical building from this area, with complex and various radon entry pathways which are correlated with the geology of soil. This building was chosen as pilot house due to the fact that it requires different ventilation systems or other remedial measures to be installe

Recent archaeological researches in the Vârghiș Gorges karst area (Eastern Carpathians, Romania). A synthesis of the 2014–2020 campaigns

The Vârghiș Gorges karst system (Perșani Mountains, Eastern Carpathians) constituted a point of interest for speleologists, paleontologists and archaeologists since the second half of the 19th century. Their efforts succeeded in highlighting the notable archaeological potential of the area, although the actual research results were not always thoroughly reported. Since 2014, our team reunited specialists from 10 different institutions and various fields of research and initiated archaeological excavations, coupled with achaeozoological, sedimentological and chronometric investigations, in several caves within the Vârghiș Gorges. As the paper below will show, although the results obtained so far are definitively informative, further investigation are clearly needed, in order to accurately clarify aspects pertaining to the intricate cultural and chronological framework.Sistemul carstic din Cheile Vârghișului (Munții Perșani, Carpații Orientali) a reprezentat un punct de interes pentru speologi, paleontologi și arheologi încă din a doua jumătate a secolului XIX. Demersurile acestora au evidențiat remarcabilul potențial arheologic al zonei, chiar dacă rezultatele investigațiilor propriu-zise nu au fost întotdeauna prezentate exhaustiv. Începând cu anul 2014, am alcătuit o echipă de specialiști din zece instituții de cercetare și variate domenii de specialitate și am inițiat săpături arheologice, însoțite de cercetări arheozoologice, sedimentologice și cronometrice, în câteva peșteri din Cheile Vârghișului. Așa cum reiese din observațiile prezentate, deși rezultatele obținute până în prezent oferă informații noi, cercetări viitoare sunt necesare pentru o mai bună înțelegere a complexității cadrului cronologic și cultural.Cosac Marian, Murătoreanu George, Veres Daniel, Niţă Loredana, Schmidt Cristoph, Hambach Ulrich, Radu Alexandru, Cuculici Roxana, Buzea Dan Lucian, Ștefan Dan, Mărgărit Monica, Vasile Ştefan, Dumitraşcu Valentin, Roşu Mariana, Petculescu Alexandru, Sava Tiberiu, Georgescu Valentin, Șerbănescu Gabriel, Geambașu Ionel.
