Floating Peat

Lateral expansion of floating vegetation mats over the surface of aquatic ecosystems (terrestrialization) is one of the ways of peatland development. This process was commonly studied in kettle-hole lakes, whereas karst ponds have received less attention. We used a suite of palaeoecological analyses at Karstovoe mire (Mordovia, Russia) to reconstruct the formation of a floating Sphagnum-dominated peat mat over the karst pond. The results show that the floating peat mat had covered the central part of the pond by ca. AD 1600. Remains of Scirpus sp. and Calamagrostis sp. in the basal layers indicate that these plants might form a framework on which Sphagnum mosses and sedges were established. The terrestrialization could be triggered by the ‘Medieval Warm Period’ (AD 950–1250) as droughts reduce water levels and allow the pioneering plants to colonize exposed bottom sediments on the margins of lakes. Later, the development of the mire was mainly driven by autogenic factors that could be explained by the relatively stable hydrological regime in freely floating or poorly attached vegetation mats. In the mid 19th century, the surface wetness of the mire started to decline that can be related to both increased human activity associated with fires and to a greater thickness of the mat so that autogenic and allogenic effects were difficult to disentangle. In less than a century after that, the fen transformed to a pioneer raised mire. Our results show complex and context-dependent effect of autogenic and allogenic factors on the development of floating peat mats.

Vegetation cover and environmental factors were studied in the system of karts mires in the broad- leaved forest zone in Tula Region, Central European Russia. Mires are formed in the sinkholes and characterized by rather low anthropogenic disturbances. These mires are characterised by floating peat mats and variety of vegetation communities which are differ by ecological conditions (water levels, acidity and nutrition). Development and growth of floating mats change water and mineral feeding that leads to succession of vegetation communities.

Floating Peat

In order to rectify perceived problems in the nineteenth century autochthonous and allochthonous theories of coal formation, an alternative theory was proposed that hypothesized that sylvo-marine, lycopod-dominated, floating peat mats were responsible for the development of Carboniferous coals. This pelagochthony theory was not widely accepted at the time but recently has been resurrected in order to explain the formation of Carboniferous coals well within the “Biblical time scale.” Numerous, unsubstantiated “facts” have been proposed to support the floating mat hypothesis including: the supposed hollow construction of arborescent lycopods; the extensive intertwining of stigmarian axial systems; a supposed continuous transgression of the shallow epeiric sea; a supposed stratified water column below the floating mat; and others. An examination of lycopod anatomy and morphology negates the contention of hollow arborescent lycopods and allows establishment of criteria to aid in the identification of in situ plants. An evaluation of the floating mat hypothesis in perspective demonstrates the untenable character of this proposed coal-forming mechanism. Reattachment of the floating mat is highly probable in the shallow epeiric sea, either by stigmarian axial systems proper, or helically arranged ‘rootlets.’ Isostatic adjustments of the mat would continue downwards as more biomass is generated by maturation of the trees. However, if this is ignored, meteoric waters introduced onto the surface of the mat would promote rapid decay in the tropical environment, and may preclude peat accumulation.
