Formation of Calcic, Gypsiferous, and Saline Soils that can grow there. Ccalcite, gypsum, and more soluble salts such as chlorides, and sulphates of Mg, K and Na, and carbonates of Na and K are common in certain sedimentary rocks and soil, but do not occur in primary (igneous) rocks. The constituent cations are found in common rock-forming silicate

Formation of Andisolsence. The Ah horizon is dark-coloured and normally very high in organic matter (often more than 10%) stabilized by aluminium. The B horizon is usually dominated by amorphous aluminium silicates (allophane, impogolite). Andisols form mainly on volcanic ashes, but can also be found on other highly wea

Analysing Complex Situationsshift in the dominant process. This is the reason why most soils have a complex genesis. Major shifts in climate, of course, may competely change soil formation at a specific location. Such shifts are evident in the Holocene of western Europe (e.g. different climates during the Boreal, Atlantic, and
