Serpentine soil is a magnesium rich, calcium, potassium and phosphorus poor soil that develops on the regolith derived from ultramafic rocks. Ultramafic rocks also contain elevated amounts of chromium and nickel which may be toxic to plants.As a result, a distinctive type of vegetation develops on these soils.alc carbonation reactions occur in ultramafic rocks at lower greenschist through to granulite facies metamorphism when the rock in question is subjected to metamorphism and the metamorphic fluid has more than 10% molar proportion of CO 2 (carbon dioxide).
or. soil, essentially clay mixed with carbonate of lime, highly valued as a dressing or fertilizer. It crumbles rapidly and easily. Marl in which the lime is in the form of invertebrate shells is called shell marl.The term is loosely used for a variety of soils, some of which are low in lime content, e.g., the greensand marl of New Jersey. Marling of soil tends to lighten it, correct acidity, and promote nitrification.arl. a sedimentary rock composed of calcite or dolomite and clay minerals. The ratio of carbonaceous to clay components may vary. Generally marl is identified as rock containing from 30 to 90 percent CaCO 3 or MgCO 3 and, correspondingly, from 70 to 10 percent clay particles.
