  • Chemicals In Basalt Rock

Enhanced Rock Weathering as a Source of Metals to …

Enhanced weathering of (ultra)mafic rocks has been proposed as a promising approach to sequester atmospheric CO2 and mitigate climate change. However, these silicate rocks contain varying amounts of trace metals, which are essential cofactors of metallaenzymes in methanogens. We found that weathering of crushed peridotite and basalt significantly …

Metabasalt

The Rompas prospect area (Fig. 5.4.1) is dominated by a north-trending resistant ridge formed by metabasalt, carbonate-rich, and carbonate-albite rocks (Fig. 5.4.3).On the ridge crest, these rocks either crop out or are covered by a thin glacial till (generally less than 1 m). On either side of the ridge, small lakes, peat bogs, and thicker till are abundant with isolated …

THERMAL PROPERTIES OF ROCKS

These plots are from tables of Robie and Waldbaum (1968). The specific heat of a rock is easily calculated from values of the minerals in its mode (fig. 43 and discussion); this approach is unique, as the usual calculation is from oxides from chemical analyses. Values of specific heat for a rock are useful for many other purposes than heat

Basalts have a higher Ni concentration (140 mg/kg) than various other types of rock on the Earth's surface (McGrath, 1995).With the weathering of basalts, Ni existing in the primary dark minerals (e.g., olivine, pyroxene, magnetite and ilmenite) (Rollison, 1993, Trescases, 2012) is released into the soil and water bodies, where it is absorbed by crops and eventually enters …
