Strengthening potential of recent peat dating.

This study concerned high-resolution age reconstructions of modern organic deposits collected from peatlands distributed in Central Europe. The main focus was on Pb radioisotope as a fundamental geochronometer along with C and Pu radioisotopes used for dating verification. In addition to simple classical models such as CF/CS or CF, the new approach formulated upon the Plum method was implemented.

Geographical drivers of geochemical and mineralogical evolution of Motianling peatland (Northeast China) exposed to different sources of rare earth elements and Pb, Nd, and Sr isotopes.

Geochemical shifts triggered by surface runoff and atmospheric fallout in a Chinese peatland were investigated by using Pb, Sr, and Nd, REE and by SEM mineralogical analysis. Motianling peatland (Northeast China) is located at 1670 m a.s.

Deposition of mullite in peatlands of southern Poland: Implications for recording large-scale industrial processes.

Mullite, a pure aluminosilicate (AlSiO), is a rare natural rock component, known for centuries as a very resistant ceramic material. It is also a common waste product of high-temperature coal combustion that is emitted in quantity from coal-based power stations. The occurrence of mullite in two Sphagnum-dominated peatlands located near the Upper Silesia industrial region in southern Poland is described.

Abrupt ecological changes in the last 800 years inferred from a mountainous bog using testate amoebae traits and multi-proxy data.

Mountainous peatlands of Western Sudetes are considered a unique habitat in Central Europe. The region contains one of the largest raised bog complexes in temperate Europe and is thus of great importance for biodiversity conservation. In this first high-resolution study from this region we use long-term ecological data to assess how these mountain wetland ecosystems responded to anthropogenic impacts and climate change.

Quantitative determination of minerals and anthropogenic particles in some Polish peat occurrences using a novel SEM point-counting method.

A method is proposed for determining the mineral composition of peat using scanning electron microscope. In an illustrative example, five groups of particles occurring in amounts of >0.05% are distinguished in peat from Puścizna Mała bog in the Carpathian foreland, Poland.

Heavy metal behaviour in peat--a mineralogical perspective.

The mineralogical composition of a 40 cm subsurface layer of transitional mire 'Bagno Bruch' (southern Poland) polluted with atmospheric dust was studied using scanning electron microscopy. The mire is located 9 km to the east of a zinc smelter on the northern limit of industrial Upper Silesia in southern Poland. Concentrations of zinc, lead and cadmium reach values of 494, 238 and 16 mg kg(-1), respectively, in the peat layer.
