components dissolve. The alumino silicate minerals are the great
example of the incongruent class, releasing Na], K+, HCO-, etc.
ions in reaction with J water but retaining most of their atoms in
re-ordered solids such as kaolinite. The karst minerals are all
congruent in normal conditions. Incongruent solution of dolomite
and precipitation of calcite may occur in some exceptional
conditions mentioned later. The sample of congruent minerals in
Table 3. 1 contains all the common elements of crustal rocks except
Fe, and furnishes a majority of the common dissolved inorganic
species. The range of solubility is enormou . Gibbsite is an
example that is insoluble to all intents and purposes; even in the
most favourable circumstances encountered on the surface of this
planet physical processes will disaggregate it and remove it as
colloids or larger grains before there is significant solution
damage. Rock salt (halite) is so soluble that it is rapidly
destroyed in outcrop except in the driest places; it is principally
important for its role in interstratal karstification. Sylvite and
mirabilite are rarely encountered and never in great bulk. They
occur as minor secondary cave minerals (see section 8. 4). Gypsum
and anhydrite are quite common in outcrop. Karst features develop
upon them rapidly because of their comparatively high solubility.
Limestone and dolomite are common in outcrop. Their maximum
solubility varies with environmental conditions but never
approaches that of gypsum. Quartzite and siliceous sandstones are
equally common in outcrop.
