High Fluoride

The north east of Tunisia ore deposits (Hammam Zriba) contain a large amount of fluorides constituting a risk of environmental pollution as well as risks to human and animal health. The aim of our work was to assess the levels of fluorides in the water and blood of sheep in the east of Tunisia region. This analysis study included 78 water samples and 60 blood samples taken during 3 days in the year 2019, from a sheep herd at Hammam Zriba delegation. The determination of fluorine concentration in the samples was carried out by potentiometry with a selective electrode type ISE combined Fluoride perfectION™. High Fluoride concentrations were found at a mean of 1.62 ± 1.18, 1.45 ± 0.98, and 2.65 ± 1.61 mg/l, respectively, in running, deep, and stagnant waters. In addition, 83.3% of the animals reared within 400 m of the study area had elevated fluoride levels in the blood exceeding the usual values (fluoremia> 0.15 mg/l). The concentration of fluoride in the blood of the animals decreases with increasing distance from the mine.

The article discusses the actual aspects of the metallogeny of the Pacific volcanic belts (PVB), which are a complexes of volcanogenic-plutogenic formations associated with the development of the marginal lithosphere and has an expressive specificity of ore formation. It is shown that over time the notions of metallogenic homogeneity of PVB have received a new justification from the position of global plate tectonics. Metallogenic significance of Ag/Au relationships in ore deposits of the PVB is shown. The correlation between porphyry-epithermal and the VMS ore-forming systems, regenerated and rejuvenated epithermal deposits is discussed. Global metallogenic homogeneity of the Pacific ore belt suggests a wide development of analogues of American volcanogenic deposits in its Asian half, including in the North-East of Russia. The main part of the internal zone of the Okhotsko-Chukchi marginal volcanic belt the Udo-Murgal island-arc belt, as well as the Uyandino-Yasachensky and Oloysky volcanic belts, are similar in geological structure not only to the Japanese green tuffs province, but also to other Pacific volcanic zones of the island-arc type and, therefore, within their limits, there is a high probability of revealing the entire variety of deposits of the VMS ore-formation series.

The article presents data on the scientific and organizational activities of the Head of the NEISRI Laboratory of Archeology, History, and Ethnography, Doctor of Historical Sciences, Professor, Corresponding Member of the Russian Academy of Sciences N. N. Dikov as well as on the creation of the North-East Asian Complex Achaeological Expedition (NEACAE) and the results of archaeological research performed by its detachments. N. N. Dikov's important contribution to the organization of archaeological research in the North-East Russia and his achievements in the study of ancient cultures are noted. The NEACAE formation contributed to a greater coverage of the territory of the north of the Far East by archaeological research, the discovery of a significant number of archaeological sites in Chukotka, Kamchatka, Kolyma, and on the Okhotsk coast.

The paper reconstructs the process of accumulation of scientific knowledge on the geology of the North-East of Russia and evaluates the results. On the basis of extensive collections of documents in the State Archive of the Russian Federation, Russian State Archive of Economy, Russian State Archive of Socio-Political History, State Ar-chive of the Magadan Region, and local publications of 1930–1940, and memoirs of contemporaries we ac-cessed the contribution of geologists of joint-stock company «Soyuzzoloto» to the sharing of scientific knowledge on the mineral potential of North-East Russia. This provides better understanding of the practice of mining development in the North-East of Russia, introduces the valuable types of mineral raw materials into economic circulation, personal aspects of this phenomenon. The huge amount of factual material collected by «Soyuzzoloto» required the scientific and technical support of the mining industry. All necessary resources of the North-East of Russia were organized of in a single center ––the «Dalstroy» trust.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.
