Thickness of the Upper Hrušov Member (Namurian) in the Czech part of the Upper Silesian Basin
'Masaryk University Press', 2013Co-Authors: Beneš Luboš, Jirásek Jakub, Hýlová Lada, Sivek MartinAbstract:Map of the thickness of the Upper Hrušov Member (Namurian, Mississippian) was made. It is based on Exploratory Boreholes´ information from the Czech part of the Upper Silesian Basin. The thickness varies from 18.69 m up to 669.49 m. Highest values are situated in a NE–SW trending zone west of the Orlová Structure in the northern part of the Příbor area and in the western part of the Ostrava area. Total thickness of the Upper Hrušov Member is decreasing to the east and shows evident west-east polarity. Western part of the post-erosive area of the Upper Hrušov Member represents the axis of maximum subsidence of the basin in times of sedimentation. The zone of reduced thickness is the original eastern part of the basin. Western part of the basin is not preserved due to the post-Carboniferous erosion.Map of the thickness of the Upper Hrušov Member (Namurian, Mississippian) was made.

Coal-bearing capacity of the Upper Hrušov Member (Namurian) in the Czech part of the Upper Silesian Basin
'Masaryk University Press', 2013Co-Authors: Beneš Luboš, Jirásek Jakub, Hýlová Lada, Sivek MartinAbstract:Maps of the coal-bearing capacity, number and total thickness of coal seams of the Upper Hrušov Member (Namurian, Mississippian) were made. They are based on Exploratory Boreholes´ information from the Czech part of the Upper Silesian Basin. Absolute coal-bearing capacity varies from 0.00 % to 2.57 %, and their total thickness from 0.00 m to 9.43 m. All mentioned parameters reach their maximum in NNE–SSW trending zone west of the Orlová Structure. This situation supports the hypothesis, that preserved part of the Upper Hrušov Member could form the subsidence axis of the basin and its eastern part whereas the western part is not preserved due to post-Carboniferous erosion, similar as in the case of Lower Hrušov Member.Maps of the coal-bearing capacity, number and total thickness of coal seams of the Upper Hrušov Member (Namurian, Mississippian) were made.

Thickness of the Lower Hrušov Member (Namurian) in the Czech Part of the Upper Silesian Basin
'Masaryk University Press', 2012Co-Authors: Vebr Lukáš, Jirásek Jakub, Hýlová Lada, Sivek MartinAbstract:Map of the thickness of the Lower Hrušov Member (Namurian, Mississippian) was made.

chronology and tectono sedimentary evolution of the upper pliocene to quaternary deposits of the lower guadalquivir foreland basin sw spain
Sedimentary Geology, 2011Co-Authors: Josep Maria Salvany, Juan C Larrasoana, C Mediavilla, Ana RebolloAbstract:This paper presents new litho, chrono and magnetostratigraphic data from cores of 23 Exploratory Boreholes drilled in the Abalario and marshlands areas of the lower Guadalquivir basin (the western sector of the Guadalquivir foreland basin, SW of Spain). The lithologic logs of these Boreholes identify four main sedimentary formations, namely: Almonte Sand and Gravel, Lebrija Clay and Gravel, Marismas Clay and Abalario Sand, respectively interpreted as proximal–alluvial, distal–alluvial, alluvial-estuarine and aeolian. From radiocarbon and magnetostratigraphic data, these formations were dated as Upper Pliocene to Holocene. In the marshlands area, three main sedimentary sequences are present: an Upper Pliocene to Lower Pleistocene sequence of the Almonte and Lebrija (lower unit) formations, a Pleistocene sequence of the Lebrija (upper unit) and the lower Marismas formations, and a latest Pleistocene to present-day sequence of the upper Marismas Formation. The three sequences began as a rapid alluvial progradation on a previously eroded surface, and a subsequent alluvial retrogradation. In the third sequence, estuarine and marsh sediments accumulated on top of the alluvial sediments. The aeolian sands of the Abalario topographic high developed coeval to alluvial and estuarine sedimentation after the first alluvial progradation, and continuously until the present. Correlation with the surrounding areas show that the sequences are the result of the forebulge uplift of the northern margin of the basin (Sierra Morena) and the adjacent Neogene oldest sediments of their northern fringe, both form the main source area of the study formations. This uplift occurred simultaneous to the flexural subsidence (SSE tilting) of the southern part of the basin, where sedimentary aggradation dominated.

Site Characterization Data from the U3ax/bl Exploratory Boreholes at the Nevada Test Site
2005Co-Authors: Bechtel NevadaAbstract:This report provides qualitative analyses and preliminary interpretations of hydrogeologic data obtained from two 45-degree, slanted Exploratory Boreholes drilled within the Area 3 Radioactive Waste Management Site (RWMS) at the Nevada Test Site. Borehole UE-3bl-D1 was drilled beneath the U3ax/bl mixed waste disposal unit, and Borehole UE-3bl-U1 was drilled in undisturbed alluvium adjacent to the disposal unit. The U3ax/bl disposal unit is located within two conjoined subsidence craters, U3ax and U3bl, which were created by underground nuclear testing. Data from these Boreholes were collected to support site characterization activities for the U3ax/bl disposal unit and the entire Area 3 RWMS. Site characterization at disposal units within the Area 3 RWMS must address the possibility that subsidence craters and associated disturbed alluvium of the chimneys beneath the craters might serve as pathways for contaminant migration. The two Boreholes were drilled and sampled to compare hydrogeologic properties of alluvium below the waste disposal unit with those of adjacent undisturbed alluvium. Whether Borehole UE-3bl-D1 actually penetrated the chimney of the U3bl crater is uncertain. Analyses of core samples showed little difference in hydrogeologic properties between the two Boreholes. Important findings of this study include the following: No hazardous or radioactive constituents of wastemore » disposal concern were found in the samples obtained from either borehole. No significant differences in physical and hydrogeologic properties between Boreholes is evident, and no evidence of significant trends with depth for any of these properties was observed. The values observed are typical of sandy materials. The alluvium is dry, with volumetric water content ranging from 5.6 to 16.2 percent. Both Boreholes exhibit a slight increase in water content with depth, the only such trend observed. Water potential measurements on core samples from both Boreholes show a large positive potential gradient (water moves upward, via evapotranspiration) for the entire vertical depth. Very little liquid flow occurs through the vadose zone. The direction of flow in the upper vadose zone (approximately the upper 35 meters) is upward, based on unsaturated hydraulic conductivity data, water potential data, and environmental tracer data.« less
