Tulakan Subdistrict, Pacitan Regency, East Java Province. This area is part of the Southern Mountain Zone of East Java, which is the Sunda-Banda magmatic arc of Oligo-Miocene age, where there are alterations and indications of valuable ore minerals. Field magnetic data is taken in an area of 1 x 1 km, with the looping method on the grid trajectory within 200 x 100 m. Then, magnetic data correction and data processing were carried out with Oasis Montaj. From the magnetic anomaly map, the value of high magnetic intensity in the southern part is fresh (intrusive) andesit-dasitic rock as host rock which causes alteration, in the middle has a low magnetic intensity value which is in the direction of the relatively NE-SW river direction, whereas in the north with high intensity is fresh andesite lava. From the image data, it can be seen that the straightness pattern of the geological structure which is dominated by the extensional structure with the direction of NE-SW and E-W is the main trap of epithermal veins carrying ore mineralization mainly Cu, Pb in the study area.

Ice and Bell Sounds are two large fiords opening out on the west coast of Spitzbergen, which cut deep into the country, both in an easterly direction towards Stor Fiord, and in a northerly direction towards the south part of Wijde Bay. The shores of the Sounds are for the most part occupied by high mountains, precipitous towards the sea, nearly free from snow during the summer, whose sides, being bare of vegetation, offer the observer an uncommonly favourable opportunity for studying the geological structure of the rocks. Within an excecdingly limited space one meets here with a succession of strata belonging to a great many different geological periods, and rich in fossils, both of the vegetable and animal kingdom.

Hydrometeorological Conditions

<p>The contemporary morphogenetic system of the South Baltic Sea is clearly changing, both in the annual and long-term weather cycle. Morphogenetic seasons are subject to change, both in terms of duration and types of morphogenetic processes and related forms of relief. The duration of the late-autumn and early-spring season is clearly increasing, which is associated with the occurring climate change and related hydrometeorological conditions. All this means that the morphodynamic types of the South Baltic coast are subject to change, the nature of which is conditioned by geological structure, relief, land cover and, hydrometeorological conditions. Undoubted individuality of the geo-diversity of the South Baltic coast in Poland are postglacial cliff coasts (50 km long).</p><p>Systematic geomorphological mapping of cliff coasts carried out since 1975 which have recently been supported by GIS methods, allow the recognition of cliff coast development mechanisms, emerging landforms and associated morphodynamic types of the South Baltic coast.</p><p>Based on repetitive geomorphological mappings, the following morphodynamic types of the South Baltic cliffs can be distinguished: landslide-type, rock fall-type, talus-type, slump-type and flow-type.</p><p>The basis for the typology of morphodynamic types of cliff coasts was the dominant types of relief forms, including lithology, exposure, land cover and hydrometeorological conditions. It can be unequivocally assumed that the morphodynamic types of the cliff coast is a good indicator feature of monitored morphogenetic systems and their space-time variability.</p><p>The effect of the observed climate change is the increasing frequency of storm surges that initiate denudation processes of an extreme nature. Another consequence of the observed climate changes is the increasing variability of morphodynamic types of the South Baltic cliff coast in the analyzed morphogenetic seasons with a greater share of landslide and rock fall-types.</p>

The alpine nappe sequence of the wider area of Aegialia and Kalavryta (Aegion sheet) is comprised of 3 alpine units, which from the lower to the upper are: (i) Arna unit, which consists of phyllites and quartzite series, (ii) Tripolis unit that consists of Tyros beds, neritic carbonate sequence and flysch and (iii) Pindos, unit which is represented with all its formations from the Triassic clastic formation at the bottom up to the Eocene flysch at the top. Pindos unit is intensively folded and tectonized forming successive thrusts with direction from east to west. The post alpine deposits are distinguished to (i) fluvial, (ii) fluvial-lacustrine, (iii) lacustrine, (iv) fan delta and (v) marine formations. The lacustrine and the fluvial formations outcrop at the south, central and eastern part of the study area, whereas the fluvial-lacustrine formations, the fan delta deposits and the marine deposits outcrop at the northern part. In the study area normal listric and oblique slip faults of great length have been observed striking WNW-ESE and NW-SE. Also, normal, oblique-slip and strike-slip faults have been observed striking NE-SWto N-S, which were which are younger than the former ones (WNWESE). The tectonic structure of the study area is characterized by the presence of horsts, grabens and blocks, which have been tilted towards SE, and S.

Literature review and analysis of previous studies of the problem was carried. The main scientific works on the research topic, as well as the main directions and stages of the study are indicated. Similar studies that were conducted on the territory of Ukraine are considered. The results of the study of heavy metals in oil samples taken from a large oil and gas region from more than thirty deposits of Ukraine are presented. All current and non-working fields are considered. The geological structure of the oil and gas province, as well as the main geochemical features of the formation of mineral deposits are considered. The main forms of finding target metals, as well as possible ways of transferring these elements in the earth’s crust are given. Samples were investigated using x-ray fluorescence and neutron activation analysis. The obtained research data in the framework of two selected methods are combined for analysis. The results obtained within the same geological structure are compared with each other to determine the effect of the physical conditions of sediment formation on the microcomponent composition of crude oil. They also compared the effect of physical conditions on the properties of oil and their ability to accumulate heavy metals. Possible causes of the abnormal accumulation of heavy metals due to the close occurrence of oil and formation water are noted. According to the results obtained, a graph is constructed of the dependence of the mineralization of oil on its depth. An exponential graphical approximation is presented to display the general trend of dependence. Possible sources and ways of migration and accumulation of heavy metals in hydrocarbons are analyzed. The concept of the migration of heavy metals in oil is proposed in conjunction with the ore mineralization of adjacent and adjacent deposits. Possible causes of differences in the concentrations of heavy metals in oil of various geological structures are indicated, as well as the main possible causes of measurement errors and complications in the selection of each of the analysis methods are specified.
