WebMafic rocks are low in silica, in the 45-50% range. Ultramafic refers to the extremely mafic rocks composed of mostly olivine and some pyroxene which have even more magnesium and iron and even less silica. These rocks are rare on the surface, but make up peridotite, the rock of the upper mantle. It is poor in silica, in the 40% or less range. The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction. The density of quartz is around 2.65 g/cm but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm . In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm ) due to a combination of the low-density of the organic materials themselves and increased porosity. For instance, pea… church of christ hanover nhWebBulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components (soil, gravel),chemical substances, (pharmaceuticals) ingredients, foodstuff, or any other masses of corpuscular or particulate matter. church of christ harrah ok
