Geological tourism and Web GIS: an innovative approach to the preservation and promotion of geological landmarks
By P. BerezinaSummaryThe article discusses geological landmarks and issues related to their preservation and popularization. Local and international practice shows the need for innovative practices in this developing sector. Geological tourism has a potential to improve socio-economic situation of local communities, as well as to preserve natural heritage and promote geosciences. As of this day, there are no means to draw public attention to Ukrainian geoheritage and geotourism, which makes this work highly relevant. Web GIS will allow users to obtain necessary spatial information online and in a visually appealing manner. Thereby, users get indirectly involved in geological tourism. However, another aim of this work is to further encourage active tourism. Research objectives include collecting information on geoheritage in Ukrainian regions, classifying geological landmarks, designing and populating a database, developing a concept and a working prototype of a Web GIS. Overall, the work discusses concepts in geological tourism, such as geoheritage, geoparks and classification of geological landmarks. The main part introduces a concept of Web GIS in geotourism industry and methodology to develop such a platform. It is expected that this Web GIS platform will systematize information about geological landmarks, in addition to encouraging geological tourism and geoconservation.

Automated morphometric analysis and its application to tectonic zonation
Authors I.E Lomakin, V.V Pokalyuk, Y.N Shuraiev and S. ShpyrkoSummaryLarge scale linear structures of the topography, clearly seen by aerial and satellite imagery and commonly referred to as lineaments, attract close attention for more than a century, and their relation with the subsurface structure is recognized and widely investigated. The lineament analysis techniques can be a method for express assessment of the tectonic structure including primary tectonic zonation of the terrain. A simple method for such analysis includes manual or semi-automated processing of DEM (digital elevation models) derived from satellite images, extracting lineament structures and statistical analysis of their orientations. It is shown, that such rose diagrams display common features for different tectonic situations with dominant lineament directions along regmatic network, but the differences of the diagrams can be a tool for primary geomorphological snap analysis of the terrain, such zonation closely matching the differences in actual tectonic setting.

Paleomagnetic data, Vendian’s part: paleomagnetic studies of ediacarian trapps from Volhynia region
Authors M.O. Baryshnikova, V.G. Bakhmutov and E.B. PoliachenkoSummaryFor several decades one of the most important problems of modern geology is determination of the duration and intensity of the formation of continental magmatic provinces (CMP). The powerful lava’s covers was used for the exploration of dynamic CMP formation, which are informative for paleotectonic reconstructions. On the territory of Ukraine they are represented by the formations of Volhynia Trapp Province.
This work shows the results of palaeomagnetic explorations samples from third’s flow of the trapps formation of Volhynia region. The characteristic component of the magnetization of the forward and reverse polarity was identified. This data helped to find coordinates of paleomagnetics poles for 580–561 Ma. Due to the received data, the location of the Baltic in the period 750–500 million years ago which was the part of mega-blocks was reconstructed and the behavior of the last was reconstructed as well

Paleotectonic reconstruction of the East European Craton in the Proterozoic (according to paleomagnetic data)
Authors S.I. Cherkes, V.G. Bakhmutov and I.B. PoliachenkoSummaryFor the Paleoproterozoic rocks of the Korsun-Novomirgorodsky pluton (anorthosites and gabbro-anorthosites), Novoukrainsky and Korsun-Shevchenkovsky massifs (rapakivi granites) which are part of the Ingul megablock, new laboratory determinations of paleomagnetic parameters were carried out. Based on the data obtained within the Ingul megablock, the positions of the averaged paleomagnetic poles were calculated for 1750 Ma (the pole coordinates are Ф = 22.5°, Л = 167.3°, dp/dm = 4.0°/7.7°) and 1770 Ma (Ф = -3.6°, Λ = 156.3°, dp/dm = 3.3°/5.3°), as well as the paleomagnetic pole for 2037.4±0.6 Ma (Ф = 43.5°, Λ = 141.6°). The obtained poles are in good agreement with those obtained earlier for the coeval complexes of the Northwest megablock ( Elming et al., 2001 ). Based on the available paleomagnetic poles, the kinematic parameters (latitudinal drift velocity and rotation speed of the blocks) for the Ukrainian Shield (Ingul and Northwestern megablocks) and Fennoscandia ( Elming et al., 2001 ) were calculated, and paleotectonic reconstructions of the relative position of these megablocks in the time interval of 1770–1750 Ma.

Quantitative Sedimentary Simulation of Braided Delta Of Oligocene Huagang Formation in Xihu Depression, East China Sea
Authors X.F. Lyu, Ch.M. Dong, Ch.Y. Lin, Ch. Jing and Q. ZhangSummaryOligocene Huagang Formation of Xihu Depression in the East China Sea found to be a thick lacustrine braided delta deposit and good low-permeability gas reservoir. Due to the study area located in deep water, with few wells drilled and limited and poor quality seismic data, its sedimentary distribution and reservoir distribution remain unclear. For this reason, we for the first time to conduct numerical sedimentary simulations to define the main controlling factors and to reconstruct its sedimentary processes with seismic data interpretation, well logging analysis and core description etc. The results indicate that the main controlling factors of this braided delta deposit in Oligocene Xihu Depression include its ancient landform before the sedimentary processes, sediment supply, source location, and lacustrine level changes. The result shows that in the early stage, braided delta front dominant on both slopes contributing as good reservoir. In the late stage, with sediment supply was abundant and the lacustrine depression shrinking with time, more braided delta plains were developing. This study provides anther evidence for good reservoir location as well as a novel insight into its future hydrocarbon exploration and development.
