Westphalian A marine horizon Dunbarella is especially important for correlation of Carboniferous in the Lublin Coal Basin (LCB), and in the other basins of the Northwest European Carboniferous Basin (NWECB). Within the horizon Dunbarella an abundant fauna, mainly Mollusca (predominantly bivalves, goniatites, gastropods) and Brachiopoda, were identified. The distribution of fauna in the analysed horizon within the investigated boreholes, fluctuates in terms of both abundance and taxonomy, and cyclic sedimentation t...

The paper presents geochemical researches of the Westphalian sedimentary rocks from the Lublin Coal Basin (Poland) with the use of various digestion methods. For all samples the concentration of main and trace elements was identified (Co, Mn, Bi, Cu, Zn, Mo, Pb, Ni, Fe, P, Mg, U, Ca, Sr, Zr, K, Rb, Al, V, Ba, Cr, Na, Th, Cd), using inductively coupled plasma mass spectroscopy (ICP-MS) The samples were prepared for testing by means of two different dissolution methods: the method of complete dissolution пїЅ multi-a...
