The main clay minerals present are kaolinite, illite and smectite. The abrasiveness index depends on the granulometric and mineralogical compositions. A lower abrasiveness is induced by the presence of a high abundance of the <2 μm fraction, small mean particle size and a large phyllosilicate content . Kaolinite and illite show good correlation with the abrasiveness index, …

• Primary minerals: present in original rock from which soil is formed. These occur predominantly in sand and silt fractions, and are weathering resistant (quartz, feldspars); • Secondary minerals: formed by decomposition of primary minerals, and their subsequent weathering and recomposition into new ones (clay minerals).

Other notable minerals that are often present are chromite, garnet, and plagioclase. It is an ultramafic rock (mafic minerals make up more than 90% of the rocks composition). Peridotite is often massive (homogeneous) just like other plutonic rocks, but it can be also layered. Layered peridotite is a cumulate rock formed by crystal settling from
==Mineral definition and classification== fjnsannjdsfnsdnnjds To be classified as a "true" mineral, a substance must be a solid and have a crystal structure.

However, one can usually assume large scale homogeneity due to random- ness of mineral distribution and grain orientation. An alternative approach is to take data from graphs and tables of measurements on rock-forming minerals to calculate from its mineral composition (mode) a combined value for a rock of its thermal conductivity, as described in
