Abstract The country’s energy security risk, as well as a desire to protect the environment from the pollution and degradation which are the results of conventional fuels acquisition - these was a motivation for intensive researches on the use of renewable energy sources in eco - innovative installations. Solar radiation is one of the self - renewable energy sources which can be used both as a source of electricity and heat. The area of research is Sosnowiec city located in the south of Poland in the eastern part of Silesia voivodeship. The solar radiation data covering the years 2003 to 2013 was used. The intra - annual variability of daily averaged solar radiation hesitated in a wide range from 0.6 kWh/m2 (December) to 5.2 kWh/m2 (June). Day duration varies on average from 10 hours in January, November and December to 17 hours in May, June and July. Day occupies 56% of the 8767 hours in year. On average the largest amount of energy reached the analyzed area in July: 157 kWh/m2 (15% of the annual average), while the smallest in December: 18 kWh/m2 (less than 2% of the annual average). The 75% of the average annual total of energy falls on the period from 1st March to 31th August (spring - summer). The range of the annual solar radiation was determined by the minimum of 980 kWh/m2 and the maximum of 1094 kWh/m2. In Sosnowiec the average annual irradiation total on the horizontal surface amounts to 1052 kWh/m2 (2003 - 2013)

Abstract Exploitation on Zn-Pb ores in Upper Silesia region dates back to the XIII century. Analyzed slags are associated with Hohenlohe smelting plant which started its work in 1804 as an iron smelter, and continued as zinc smelter since 1873. Waste material from smelting plant production was stored in Katowice - Wełnowiec, although nowadays most of it has been used for commercial purposes. Slags are composed of silicates and aluminosilicates, e.g. willemite, pyroxene- and melilite-group, K-feldspar accompanied by silico-phosphates close to perhamite, harrisonite and arsenate-chloride with composition similar to nealite. Chemical composition of most phases is simple with some unique substitutions in case of Sr and Ce

Abstract The paper aims to present the structure of weather types at two meteorological stations Galle and Nuwara Eliya (Sri Lanka). The weather type is determined as a generalized characteristic of the weather by features and gradation of selected meteorological elements. All available data on daily average, maximum and minimum air temperature, the average daily total cloud amount and the daily precipitation amount come from OGIMET database and have been used to designate weather types. The analysis was performed for the period April 2002 - March 2012. The weather types were designated based on the modified A. Woś (2010) classification of weather types. The frequency of groups, subgroups, classes, and types of weather were determined. Additionally, determined frequency of sequences of days with the same weather type. The analysis allows to conclude, that the structure of weather types at both stations was poorly differentiated. There were very stable weather conditions. In Galle, the most frequent was very warm, partly cloudy weather, without precipitation (920) and in Nuwara Eliya warm, partly cloudy weather without precipitation (820).

Abstract The aim of this research is to reconstruct palaeoredox conditions during sedimentation of the Jeleniów Claystone Formation deposits, using framboid pyrite diameter measurements. Analysis of pyrite framboids diameter distribution is an effective method in the palaeoenvironmental interpretation which allow for a more detailed insight into the redox conditions, and thus the distinction between euxinic, dysoxic and anoxic conditions. Most of the samples is characterized by framboid indicators typical for anoxic/euxinic conditions in the water column, with average (mean) values ranging from 5.29 to 6.02 μm and quite low standard deviation (SD) values ranging from 1.49 to 3.0. The remaining samples have shown slightly higher values of framboid diameter typical for upper dysoxic conditions, with average values (6.37 to 7.20 μm) and low standard deviation (SD) values (1.88 to 2.88). From the depth of 75.5 m till the shallowest part of the Jeleniów Claystone Formation, two samples have been examined and no framboids has been detected. Because secondary weathering should be excluded, the lack of framboids possibly indicates oxic conditions in the water column. Oxic conditions continue within the Wólka Formation based on the lack of framboids in the ZB 51.6 sample

Abstract The mining town of Røros located in central Norway was established in 1644 and it is known of historical mining industry related to copper. Røros was designated as an UNESCO World Heritage Site in 1980 on the base of mining culture represented by, e.g., unique wooden architecture. Slag pieces are composed of three parts differing in glass to crystallites ratio. Røros slags are composed of olivine- and pyroxene- group minerals accompanied by sulphides, with glass in the interstices. Temperature gradient and volatiles content were determined as the main factor influencing crystallization process in this material

Abstract This study provides the preliminary report about first occurrence of orthorhombic 11C pyrrhotite (Fe(1-x)S) from the Sudetes, Poland. Samples of pyrrhotite-containing two-pyroxene gabbro were found in a classic pegmatite locality in Michałkowa near Walim in the Góry Sowie Block. Based on microscopic methods, pyrrhotite is associated with pentlandite, chalcopyrite, chromite, ilmenite, gersdorffite, magnetite, biotite, magnesiohornblende, clinochlore, lizardite and talc. X-Ray diffraction (XRD) indicate that pyrrhotite has orthorhombic 11C structure and it is characterized by: a = 3.433(9) Å, b = 5.99(2) Å, c = 5.7432(5) Å, β = 90º and d102 = 2.06906 Å. Mössbauer studies confirmed the XRD data. Pyrrhotite has three sextets with hyperfine parameter values 30.8 T for sextet A, 27.9 T and 25.8 T for sextets B and C respectively, indicating orthorhombic structure, the composition near Fe10S11 and x = 0.0909

Abstract The area of the Upper Silesian Coal Basin is the most important underground mining district in Poland. Coal mines, operating in the area since the eighteenth century, have contributed to massive transformations of the landscape structure. River valleys within range of intensive exploitation activities have been undergoing vast changes. The Slepiotka River drainage basin constitutes an interesting regional example of transformations in the river's watercourse as well as in its adjacent area. It is a left-hand tributary of the Klodnica River with a length of about 8.6 km. Changes in the landscape structure that occurred between 1824-1993 have been analyzed. The starting material consisted of topographical maps that were digitized and calibrated and served as a basis to create colorful compositions. The areas occupied by the different land cover types have been calculated, which allowed to determine their participation in the drainage basin. In about 169 years, significant changes took place in the area of research considering the share of different types of cover and land use. During this time, the river changed its course, both naturally and by human activities. Increasing urbanization and technological development contributed to the diametrical transformation of the landscape structure in the discussed area

Abstract The article is devoted to the geological issue of the space-time regional prognostication of mudflow hazard. The methodology of space-time prediction of mudflows hazard by creating GIS predictive model has been developed. Using GIS technologies the relevant and representative complex of significant influence of spatial and temporal factors, adjusted to use in the regional prediction of mudflows hazard, were selected. Geological, geomorphological, technological, climatic, and landscape factors have been selected as spatial mudflow factors. Spatial analysis is based on detection of a regular connection of spatial factor characteristics with spatial distribution of the mudflow sites. The function of a standard complex spatial index (SCSI) of the probability of the mudflow sites distribution has been calculated. The temporal, long-term prediction of the mudflows activity was based on the hypothesis of the regular reiteration of natural processes. Heliophysical, seismic, meteorological, and hydrogeological factors have been selected as time mudflow factors. The function of a complex index of long standing mudflow activity (CIMA) has been calculated. The prognostic geoinformational model of mudflow hazard up to 2020 year, a year of the next peak of the mudflows activity, has been created. Mudflow risks have been counted and carogram of mudflow risk assessment within the limits of administrative-territorial units has been built for 2020 year.
