alkaline character

The alkaline character of the limestone rapidly offsets a lake's acidity, rapidly restoring the water to a neutral condition, or nearly so.

Not all rocks of the Transcandinavian Igneous Belt have a pure alkaline character, some display chemistries tending to the calc-alkaline magma series.

The Cheslatta Lake suite is characterized by its alkaline character, olivine-rich (>10 wt.%) normative mineralogy, and silica-undersaturated nature (>1 wt.% normative nepheline; hypersthene-normative rocks are uncommon).

Along with the alkaline character of the plagiogranites it can be assumed that the spreading ridge of the Troodos was situated above a subduction zone, but the mantle from which lavas were extruded was that of mantle that had recently lost a melt fraction.

The alcohol functionality, in combination with the amine and its low molecular weight imparts water solubility on the compound, and makes ester derivatives possible; the amine functionality gives the compound its alkaline character, and allows for formulation of salts of the compound.
