    dark micaceous enclave
    restite
    Opis:
    In the borehole DB-5, at a depth 1370.0 m dark micaceous enclave in granodiorite from Będkowska Valley was found. A sharp contact enclave/granodiorite is observed. The transition zone is irregularly developed around the enclave studied. It is a small enclave (3 x 6 cm), discoidal in shape. The microstructure of micaceous enclave is fine-blastic; crystalloblasts of rock-forming minerals are 0.2-0.5 mm in size. This enclave consists of: Fe-biotite (56-62 vol.%), plagioclase Ca-Na (34-40 vol.%), spinel (magnetite), corundum, and sericitic pseudo- morphs after cordierite. Its mineralogical composition is different from the Będkowska Valley granodiorite, what suggests that this rock is a medium/high-temperature restite. This rock represents residuum after partial melting of granodiorite magma in deep levels of basement of the Małopolska Massif.

    Opis:
    The lithologic variation and biostratigraphy of the Hieroglyphic Beds were examined in the Szczyrzyc Depression, where four lithologic complexes were distinguished. The biostratigraphy is based on agglutinated foraminifera and supported by scarce planktonic foraminifera. The lower part of the Hieroglyphic Beds contains non-characteristic, Ypresian foraminifers, including assemblages of small-sized Trochammina and at successively higher levels representatives of the Bartonian Ammodiscus latus Zone and the Priabonian Reticulophragmium gerochi Zone. The upper part of the Hieroglyphic Beds, composed of dark shales enriched in TOC (1–2%), corresponds to the deposits of the so-called Black Eocene, known from the Fore-Magura group of nappes. Redeposited flysch rocks resulting from episodes of subaqueous mass flow occur in the lower Bartonian part of the section.

    Opis:
    The present study deals with the application of High Resolution Transmission Electron Microscopy (HRTEM) to dark layers, occurring in the speleothems of Domica Cave (Slovakia). Chemical pre-treatment was necessary for sample purification and the effective extraction of carbon soot. For purposes of comparison, soot aggregates obtained from laboratory experiments on the combustion of beech wood and collected from a diesel engine also were studied. HRTEM analyses of combustion products permit a distinction to be made between soot aggregates that originated in different combustion processes. The diameter of spherical, primary particles depends on the conditions of combustion, notably temperature. Burning in diesel engines produces soot with relatively small, primary particles (diameter dp = 34 ± 4 nm). Primary, spherical particles of soot aggregates, obtained from the combustion of beech wood, were larger (diameter dp = 42 ± 5 nm). The diameters of primary particles of soot separated from Domica flowstones (samples DOM1 and DOM2) were similar to the wood samples (dp = 50 ± 9 nm). Another type of carbonaceous particle, obtained in the combustion process, had a spherical shape, but the diameter of about 50–500 nm was significantly larger than that of soot. Analyses performed on two samples (DOM S1 and DOM S2) confirmed that the black laminae owed their colour to particles, formed during wood combustion and later retained in the speleothems.
