“…Located in the Anatolian Highland, the geology at Hacıtugrul Tepe is composed of Tertiary sedimentary rock with thin soil layers (Pawlewicz, Steinshouer, & Gautier, 2002). Landforms around the site are gently sloped and mostly composed of erosional surfaces formed between the middle Miocene and Pleistocene (Erol, 1981;Sugai, 1992).…”

Topographic maps are fundamental for geoarchaeological field studies and archaeological excavations. However, traditional methods of topographic mapping, as well as modern high-tech methods such as airborne laser scanning and photogrammetry of high-resolution satellite images, are often cost-ineffective for field studies in terms of time, money, and labor. We here propose a method to measure topography for archaeological sites and surrounding areas quickly and accurately, using a laser range finder (LRF) and differential global positioning system DGPS. Three-dimensional coordinates of points on land surfaces are measured through the LRF, targeted from multiple measuring locations whose positions are acquired with the DGPS. The point data are then interpolated to produce a digital elevation model (DEM) using a geographic information system (GIS). High-resolution DEMs can be obtained with this method, with horizontal and vertical accuracies on the order of 10 cm. We here demonstrate the method for measuring detailed topography of the Hacıtugrul Tepe in central Turkey. Digital topography data incorporated in GIS can also be part of an archaeological database, providing opportunities for quantitative analyses of topography and archaeological materials.

“…Important changes were made in order to make the method more constant in the flow rate and to eliminate the possible release of particles able to modify, or even to occlude, the passage of the ionized sample through the sampling cone of the ICP-MS. A change of HNO 3 concentration, from 3 to 6 M, enabled an accurate washing of Rb, whose blank concentration was measured as less than 0.005 ng g −1 . For the isotopic measurements, an MC-ICP-MS system (Nu Plasma, Nu Instruments, Wrexham, UK) was employed placing the Faraday collectors in order to obtain the following series of masses: 82 Kr, 83 Kr, 84 Sr, 85 Rb, 86 Sr, 87 Sr, 88 Sr to be used to correct the 87 Sr/ 86 Sr isotope ratio by using the exponential mass fractionation law [43]. The aim of the subsequent 87 Sr/ 86 Sr isotope ratio measurements, starting from about 0.2 g of freeze-dried sample, was firstly to Pouilly et al [139] ginseng samples (0.705-0.714), but these results were contested by Rosner [18] for the following reasons: bad Rb/ Sr separation and a less accurate check of the 85 Rb/ 86 Sr ratio during acquisition, an incomplete elimination of the interfering isotopes, at least of the main elements (K, Ca, REEs, argides and oxides), when an ICP source is used.…”

and ends with man. The environment-food interaction is clear, and the production of safe and quality food is an indispensable condition for human health. The globalization of the markets, in particular of food markets, means that a greater variety of food is proposed to consumers who want to know more about its geographical origin and characteristics. For this aim, food traceability is a tool of primary importance because it acts on both food safety and quality, in order to satisfy the needs of a demanding consumer, who is interested in the quality of the food he eats and in the controls about the veracity of the brands which protect it [1, 2]. The production of high-quality food is the first step to satisfying other important aspects, such as the development of a productive but sustainable agriculture and the control of marketing. Frequently, all this is delegated to the "labelling", which is incomplete by nature or easily manipulated. Only the use of a scientific method of identification and control of the geographical origin, independent of the "labelling" and therefore of the producer, enables us to answer in full important questions concerning food safety, food quality and consumer protection. In order to achieve good results in this field, a basic mandatory condition is to develop suitable "robust" analytical methods which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds; the latter are fuelled by the modern ease of transport and conservation of products in world markets. Numerous chemical, biological and genetic methods have been developed over time in order to verify the origin of foods [3]. In this paper, we will focus on mass spectrometry, in particular on the 87 Sr/ 86 Sr isotopic ratio measurement, in that it is a "robust" analytical technique, able to fulfil the requisites needed for traceability, both to satisfy the veracity of the geographical origin and to trace possible contaminated foods back to their origin. In particular, due Abstract Today, food traceability needs to develop suitable "robust" analytical methods, in terms of the precision and of the reliability of results, which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds. This review paper highlights the most recent results obtained with the use of the 87 Sr/ 86 Sr isotopic ratio technique, when applied to the traceability of the origin of different foods for human consumption, such as vegetables, beverages, dairy products, and meat and fish products. The instrumental techniques, with the relative methodologies and the quality of the final results, will be examined and commented.

“…In order to better understand the distribution of the seeps, HYSED-RO was implemented in a GIS interface, using MapInfo Professional V. 11 (Pitney Bowes Software, Troy, NY, USA). The layers used in the evaluation of the seep occurrences are: the geological map of Romania 1:1,000,000 [45], a Digital Elevation Model (DEM) of Romania, the map of the geologic provinces in Romania [46] (Figures 2 and 3), and the geothermal map of Romania [47]. The maps were digitized and geo-referenced in WGS84 Latitude and Longitude projection.…”

In particular, the following base layers are included: tectonics [48,49]; geological provinces of Europe [46]; heat flow [47,[50][51][52]. [45], and with the main structural units of Romania (blue lines and acronyms) [48] …”

Abstract:Seeps are the expression of the migration of hydrocarbons from subsurface accumulations to the surface in sedimentary basins. They may represent an important indication of the presence of petroleum (gas and oil) reservoirs and faults, and are a natural source of greenhouse gas (methane) and atmospheric pollutants (ethane, propane) to the atmosphere. Romania is one of the countries with the largest number of seeps in the world, due to the high petroleum potential and active tectonics. Based on a review of the available literature, and on the field surveys performed by the authors during the last 17 years, we report the first comprehensive GIS-based inventory of 470 seeps in Romania (HYSED-RO), including gas seeps (10.4% of the total), oil seeps (11.7%), mud volcanoes (50.4%), gas-rich springs (12.6%), asphalt (solid) seeps (4.3%), unclassified manifestations (4.0%), and uncertain seeps (6.6%). Seeps are typically located in correspondence with major faults and vertical and fractured stratigraphic contacts associated to petroleum reservoirs (anticlines) in low heat flow areas, and their gas-geochemistry reflects that of the subsurface reservoirs. The largest and most active seeps occur in the Carpathian Foredeep, where they release thermogenic gas, and subordinately in the Transylvanian Basin, where gas is mainly microbial. HYSED-RO may represent a key reference for baseline characterization prior to subsurface petroleum extraction, for environmental studies, and atmospheric greenhouse gas emission estimates in Romania.
