采用电感耦合等离子体质谱法（ICP-MS）分析了希腊马其顿东部菲利普泥炭存款全新世和Weichselian期的6个泥炭样品中48种微量元素。还测定了这些样品的灰分含量。大多数微量元素与泥炭中的矿物质有关，而Ge、Mo、Pb、Se、Ta、Tl、U和W与有机质表现出更大的亲和力。与地壳平均值（克拉克浓度）相比，菲利普泥炭富集某些元素（Ag，As，Au，Cd，Mo，Se，Te，U和W），因为在该地区的相应矿化。菲利普泥炭还富含Cr、Cu、Mo、Pb、Sc、Sn、T、V、Y和Zn，与典型泥炭相比，也富含As、Cr、Mo、Se和U，与典型煤相比。气候和水文地质条件强烈影响泥炭形成环境，导致全新世和Weichselian泥炭之间的分化。总体而言，全新世泥炭中微量元素的含量在沼泽的北方和南部低于Weichselian泥炭。在靠近盆地西部边缘的沼泽区观察到相反的趋势。(C)1998年Elsevier Science B.V.
Six peat samples obtained from the Holocene and the Weichselian of the Philippi peat deposit, eastern Macedonia, Greece, were analyzed for 48 trace elements by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The ash contents of these samples were also determined. Most of the trace elements are associated with the minerals in the peat, while Ge, Mo, Pb, Se, Ta, Tl, U, and W display a greater affinity with the organic matter. Compared with crustal averages (Clarke concentrations), the Philippi peat is enriched in some elements (Ag, As, Au, Cd, Mo, Se, Te, U, and W) because of the respective mineralizations in the area. The Philippi peat is also enriched in Cr, Cu, Mo, Pb, Sc, Sn, T, V, Y, and Zn in comparison with typical fen peats, as well as in As, Cr, Mo, Se, and U in comparison with typical coals. Climatic and hydrogeological conditions strongly influenced the peat-forming environment resulting in a differentiation between Holocene and Weichselian peat. Generally, the Holocene peat contains lower concentrations of trace elements in the northern and southern part of the fen, than the Weichselian one. The opposite trend is observed in the fen area close to the western basin margins. (C) 1998 Elsevier Science B.V.
