    Slag from the former Hegeler Zn-smelting facility in Illinois (USA) is mainly composed of spinifex Ca-rich plagioclase, fine-grained dendritic or coarse-grained subhedral to anhedral clinopyroxenes, euhedral to subhedral spinels, spherical blebs of Fe sulfides, silicate glass, and less commonly fayalitic olivine. Mullite and quartz were also identified in one sample as . of north-central Illinois (left) and northeastern portion of the Chillicothe minute surficial geology map (right) showing areas of river deposits, glacial tills, and bedrock where they occur at land surface. The processes of data collection and interpretation undertaken for geologic mapping lead to greatly improved understanding of the Size: KB.

      The overall loss of K (22 Mg ha −1; Table 5) and a soil age of 15, years puts Skogaby roughly in the middle of the range of annual K weathering rates (1–7 mmol c m −2 year −1) estimated by Stendahl et al. for 16 podzolised Swedish glacial tills of granitic origin.

A second aim was to investigate the influence of the weathering crust and unweathered bedrock onto the mineralogy and geochemistry of tills. The material for this survey has been gathered dur.

The mineralogy, showing the changes resulting from weathering, suggests that there may be fewer than five tills, and that the sands do not all represent breaks between glacial events. Using till mineralogy and weathering evidence, there are probably only three tills beneath the Kent Till (Fig.

No mature weathering profiles have been found between these two tills, so we interpret the C1 and C2 tills as deposits separated by a minor ice-margin fluctuation during a single glacial event.

The three normal-polarity tills (A1, A2, and A3) are distinguished by texture and the coarse-sand lithology (Table 1, Figs. 3 and 4).
