X-ray microtomography (XMT) is a non-invasive and non-destructive method that has often been used to study fossils. It allows serial sections be made as little few micrometers apart; such resolution unachievable for classical sectioning; moreover, in contrast the latter, specimen not destroyed. Microtomography can, however, applied only cases where differences absorption between skeleton its infilling are great. We show this may also tabulate corals. Case studies of blastogeny based on...
The aim of the study was to apply microcomputed tomography quantitative evaluation voids and test any specific location in tooth's root canal obturations.Twenty canals were prepared obturated with gutta-percha Tubli-Seal sealer using thermoplastic compaction method (System B+Obtura II). Roots scanned three-dimensional visualization obtained. volume Feret's diameter I-voids (at filling/dentine interface) S-voids (surrounded by filling material) measured.The results revealed that none fillings...
Improvement spectrometric gamma measurements on shale cores with the use of BGO scintillation detector Spectrometric carried out rock formations belong to standard petrophysical analyses.The paper presents work performed improve possibilities recording natural radiation cores.The was related modification a logger device, creating calibration standards and developing new computer software calculate real element concentrations from measured spectra.Results obtained various methods have been...
The possibility of examining rock pore structure by the means computed X-ray microtomography was presented.Parameters characterizing structure, such as: porosity and coefficient homogeneity local examination, box counting dimension, mean chord length, normalized Euler number, as well coordination number were all determined through image analyses.Complementary methods, helium pycnometry, mercury injection capillary pressure NMR used to determine along with other factors make comparison mutual...

Selected features of carbonate rocks based on the X-ray computed tomography method (CT)The paper presents possibilities (CT) application in view representing selected a CT image.72 sections drill cores, approx. 1 m long each, were for tomographic examinations to obtain as reliable possible results.The core material represents formations various ages (from Palaeozoic Upper Cretaceous), originating from boreholes situated Carpathian Foreland area.The interpretation was connected with detailed...
Natural gas in the Polish Rotliegend Basin occurs porous and permeable aeolian sandstones, traps are mostly structural. Lithological rare occur on northern slope of Wolsztyn Ridge where fluvial sandstones overlap with alluvial facies. Both reservoir rocks this area. The X-ray micro computed tomography (MCT) results microscopic observations indicate that lithologic form highly compartmentalized vertical composed four types sandstones. profiles dominated by very low-porosity (F2), (A2, F1). A1...
Zmiany składu chemicznego i izotopowego (inwersja) metanu, etanu propanu na przykładzie gazów z formacji łupkowych Barnett (basen Fort Worth) oraz Fayetteville Arkoma) W złożach gazu w USA o najwyższej produktywności zazwyczaj występuje inwersja węgla metanie, etanie propanie.Efekt roll-over polega zmianie normalnego trendu (δ 13 C-C 1 < δ 2 3 ) odwrócony > ).Przyczyny takiej inwersji nie zostały dokładnie określone; najczęstszym wytłumaczeniem jest występowanie wtórnego krakingu ropy...
Coral-crinoid associations, where a coral overgrew crinoid's stem, were among the very common Palaeozoic benthic lasting until end of Palaeozoic. Many skeletal overgrowths described so far document syn vivo relationships. This type interaction is unknown from later, Meso- and Cenozoic deposits, to date has been recent seas. Here we analysed two individuals crinoid Metacrinus rotundus collected mesophotic depths off Japanese Pacific coast, overgrown by single zoantharian polyp Abyssoanthus...
