WebAug 1, 2002 · The main effects of applying finely ground, especially glass-rich basalt to highly depleted tropical soils include: small increases in pH (liming effect); reduction of Al … WebMay 1, 2024 · The Wenchang basalt profile is highly weathered (CIA ∼100%), and alkalis (Na, K, and Ca) are mostly lost. Under strong leaching, the Sr–Li input from ocean aerosol can affect the entire profile, and secondary minerals have undergone multiple adsorption and desorption processes (forming the wide δ 7 Li range).

Animals, plants, and atmospherics (such as rain or extreme temperatures) cause weathering. The following table can be used to classify the level of weathering for … See more The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent. Accessory minerals present in relatively minor amounts include iron oxides and iron-titanium oxides, such as magnetite, ulvöspinel, and ilmenite. Because of the presence of such oxide minerals, basalt can acquire strong magnetic signatures … develop your writing style
