“…Mineral and chemical composition of ultramafic rocks may be affected by processes taking place after serpentinization. For example, Kukuła et al [109] stated that hornblende (Ca 2 [Mg 4 (Al, Fe)]Si 7 AlO 22 (OH) 2 ) in peridotite from the Popiel Hill (southwestern Poland) originates from contact metamorphism with the Karkonosze Granite Intrusion. Therefore, postserpentinization processes change the Ca and Mg budget in ultramafic soils.…”

Weathering of peridotites and serpentinites leads to the formation of ultramafic soils characterized by several peculiar properties such as low Ca/Mg ratios and elevated concentrations of Ni, Cr, and Co. The aim of our study was to investigate the effects of Ca 2+ and Mg 2+ on seed germination in the environment that mimic ultramafic and non-ultramafic soils. We hypothesized that Ca and Mg alleviate toxicity of Ni, Cr, and Co in relation to seed germination and root length. Regardless of concentration, metal salts inhibited seed germination and root growth for almost all studied plant species compared to control. An increase in germination was observed in treatments containing high concentrations of Ni 2+ and Co 2+ with the addition of Ca 2+ and Mg 2+. Roots of plants had greater length in high Ni 2+ and Co 2+-treatments with Ca 2+ and Mg 2+ in relation to metal treatments without the addition of Ca 2+ and Mg 2+. In low-content metal treatments with Ca 2+ and Mg 2+ , roots had similar or smaller lengths compared to metal treatments. Our results demonstrate that Ca 2+ and Mg 2+ alleviate toxicity of Ni 2+ and Co 2+ during seed germination and root growth under conditions simulating ultramafic soils. Therefore, in soils derived from ultramafic rocks enriched in Ca, an increase in germination and root growth is expected as opposed to soils occurring on Ca-poor ultramafic rocks. In non-ultramafic soils containing relatively low amounts of Ni, Cr, and Co, the roles of Ca and Mg are negligible.

The Oligocene/Miocene basanite from Pilchowice (Sudetes Mts., SW Poland) carries numerous small xenoliths of mantle peridotite, mostly harzburgite. The Pilchowice xenolith suite is dominated by harzburgites and dunites containing olivine Fo 90.2-91.5 (group A). The peridotites of group B (olivine Fo 88.6-89.4), and C (olivine Fo 83.2-86.5) are subordinate. The peridotites suffered from significant melt extraction (20-30%) and were subsequently subjected to metasomatism. Three different trace element compositional patterns of group A clinopyroxene occur, which are typical of silicate melt, carbonatite melt and silicate-carbonatite melt metasomatism, whereas groups B and C were affected by silicate melt metasomatism only. The Pilchowice basanite occurs at the contact of Karkonosze-Izera Block and Kaczawa Complex, two major geological units of Sudetes. The Pilchowice xenolith suite documents underlying lithospheric mantle of composition and depletion degree similar to those described in the whole Lower Silesian mantle domain, which forms NE termination of Saxo-Thuringian zone of the European Variscan orogen. The crustal structure of the orogen is, therefore, not mirrored in the mantellic root.
