The Tokaj Mts, situated in the northeastern part of the inner arc of the Carpathians, forms a part of a Miocene calc-alkaline andesitic-dacitic-rhyolitic volcanic island arc. The ancient volcanic structures were reconstructed on the basis of the 1:50 000-scale and 22 sheets of the 1:25 000-scale geologicpetrologic maps, as well as the revision of the volcanic facies in 150 boreholes. Multispectral and SAR satellite imagery, aerial photos, data and maps of airborne geophysical surveys (magnetic and radiometric), gravity-filtered anomaly maps, geochemical (soil and stream sediment Au, As, Sb, Hg) concentration distribution maps and the K/Ar dating of 132 samples from 80 paleomagnetic measurements were also used.The anomalies were only taken into consideration in the interpretation if the coincident results of at least 3 methods indicated the presence of any volcanic structure. In consequence, 91 map-scale volcanic structures were identified by morphology -complex calderas, single lava domes, volcanic fissures, subvolcanic intrusions, diatremes, stratovolcanoes and postvolcanic formations. Conclusions were also drawn regarding the link to the volcanic structures and prospective occurrences of the mineral resources of the Tokaj Mts: andesite, dacite, welded zeolitic tuff, K-metasomatite, perlite, pitchstone, pumice, bentonitic, illitic, kaolinitic, diatom-bearing and silicified lacustrine sediments, hydrothermal Au-Ag and Pb-Zn veins, and Hg stockwerks.Key words: exploration methods, volcanoes, island arc, calc-alkaline, morphology, complex interpretation IntroductionThe subject matter was developed under the leadership of Tibor Zelenka by Pál Gyarmati, János Kiss, László Vértesy, István Horváth, Zoltán Pécskay and Emõ Szalay, and was supported by OTKA project T022769.

Exploration historyReviewing the publications on volcanology concerning the Tokaj Mts from the last 250 years, one can find remarkable statements from almost every author.The essays of Beudant (1822), Richthofen (1861) and Wolf (1869) are the pioneers of the recognition of geologic formations. The fundamental monograph of Szabó (1867) entitled "Tokaj-Hegyalja és környékének földtani viszonyai" (Geologic features of Tokaj-Hegyalja and its surroundings) provided the basis for the recognition of the volcanic structure of the mountains. Szádeczky (1897) was the first to recognize that the amphibole andesite had broken through the rhyolite.Pálfy (1927) stu...

“…During the first phase of the geochemical mapping of the mountainous areas (Hartikainen et al 1992) the microelement content of the four sampling agents (heavy mineral concentrates, stream sediments, composite soil and composite rock fragment samples) were compared. Results showed that the expected values are similar over the drainage basins while the variability increases from the heavy mineral concentrate to the rock fragment.…”

South of the Sudetes and Tatra Mountains young sediments contain more of almost all micro-and mesoelements than those to the north of the Carpathian Mountains, which were covered by ice during the Late Pleistocene. As detailed investigations show this larger unit is a collection of many individual geochemical regions, among which there are four on the area of Hungary: the region of soil calcification in the central part of Hungary, the slope debris of the foothills of the Eastern Alps, the floodplains of the rivers of Eastern Hungary that are contaminated with the waste material of heavy industry, and the rest of the country. No general geochemical background can be given to the whole; the background value intervals for each element shall be given for each geochemical region separately. In Eastern Hungary, where those rivers flow that originate from the heavy industrial centers of Transylvania and Slovakia, the toxic elements can locally exceed the limit value. In the central part of the country, however, the micro-elements are frequently found below the minimum concentration required, since a carbonate accumulation zone develops above the groundwater level and the carbonate minerals contain low amounts of nutrient elements.Key words: trace elements, geochemical maps, background level, regional anomalies, heterogeneity, stream sediment, floodplain sediment, soil calcification Soil-forming sediments and their origin in HungaryGeographers divide the loose plains and hilly regions of Hungary into five separate units (Pécsi 1967): Tisza Plain, Danube Plain, Little Plain, West Hungarian Borderline and Transdanubian Range.

These regions are the main areas of agricultural production of Hungary.The three plains are accumulation regions where rivers coming from the surrounding mountains deposit their alluvium. In regions where the groundwater level is located near to the surface the sediments could have undergone salinization.According to the same type of division, there are two mountainous areas in Hungary: the Transdanubian Mountains and the North Hungarian Range. The mountains are predominantly built up of older, Mesozoic rocks, while the intermountain basins are filled with younger sediments. On the hard rocks mostly younger sediments are deposited with variable thicknesses.With regard to agriculture, forestry and environmental geology, the loose sediments are of importance in the mountainous areas as well. Danube PlainThe largest area of blown sand of the country is situated above the ridge of the Danube-Tisza Interfluve where the thickness of the blown sa...

“…Hydrogeochemical study is a useful tool to identify these processes that are responsible for groundwater chemistry (Jeevanandam et al 2007). There are many examples of the use of Hydrogeochemistry in mineral exploration and environmental studies in the world (Miller et al 1982;Hartikainen 1992;Giammanco et al 2007;Verplanck et al 2008;Halim et al 2009;Hame et al 2014). Appreciation of basic principles in aqueous geochemistry provides a means to understanding element mobility's and interpreting dispersion patterns, with applications in both the mineral exploration and environmental disciplines.…”

Geochemical data from 67 spring locations within the 3780 km 2 , in Jebal-e-Barez area, south eastern of Iran, were analyzed with the purpose of developing a suitable regional geochemical exploration method for CuAu ± Mo mineralization in such potential area. Statistical data analyses, graphical methods, and geochemical characteristics of waters and mineral saturation indices were used to identify mineralization potential regions. Hydrogeochemical data of samples suggested that the groundwater is mostly Ca ? Mg ? HCO 3 type (67.16 %). The sulfate-type waters are mainly clustered around the mineralization occurrences. The groundwaters have low concentrations of base metal and Cu, Au, Mo and SO 4 can be used as direct indicators of Cu mineralization in study area. Ni is an indicator of Cu mineralization and travertine springs distribution impress the hydrogeochemical evaluation. On this basis, it is concluded hydrogeochemical exploration can be used as an effective regional exploration method.
