Laboratory tests indicate that 15% O2, instead of 12%, is required for the propagation a widespread forest fire, 3% increase from what was previously assumed. The presence wildfire records in Upper Triassic and Lower Jurassic Central Europe suggests lower limit O2 during this time at least 15%. Wildfire are based on co-occurrence charcoal fragments elevated concentrations pyrolytic polycyclic aromatic hydrocarbons (PAHs). In all samples large to medium-sized angular, suggesting they were...

A palynological study of the uppermost Famennian section from Kowala Quarry (Holy Cross Mountains, central Poland) allowed recognition two miospore zones: LV ( Retispora lepidophyta–Apiculiretusispora verrucosa ) and LN lepidophyta–Verrucosisporites nitidus ). Based on palynology sedimentology, black shale within upper part is identified as equivalent to Hangenberg Black Shale, which known globally. This contains compounds characteristic photic zone euxinia, including isorenieratane its...
Using the pyrolysis-gas chromatography–mass spectrometry and off-line pyrolysis/silylation methods for lignites from three Miocene brown coal basins of Poland resulted in characterization many organic compounds, including dominant cellulose degradation products such as levoglucosan, 1,6-anhydro-β-d-glucofuranose, 1,4:3,6-dianhydroglucopyranose. Levoglucosan is a general source-specific tracer wood smoke atmosphere recent sediments. The presence unusually high levels this compound pyrolysates...
A wide range of various proxies (e.g., mineralogy, organic carbon, inorganic geochemistry, C and Mo isotopes, framboidal pyrite) were applied for interpretation changing oceanic redox conditions, bioproductivity, the regional history magmatic activity. This resulted in internally consistent late Famennian Hangenberg Crisis subtropical deepest water sites epeiric Rhenohercynian Saxo–Thuringian basins, as well more open Paleo-Tethys Ocean. High mercury concentrations detected all studied...
Abstract. The supplementation and provision of appropriate nutrients to microorganisms, which are often lacking in the natural environment essential critical for microbial growth. One such element is nitrogen, most found Earth's atmosphere. In this study, we present evidence nitrogen processing anaerobic N2-fixation by microorganisms naturally sedimentary organic matter. Miocene detritic lignite from opencast mine was incubated under conditions dark (headspace atmosphere 85 % N2, 10 CO2, 5...
