WebCleavage is a type of rock foliation, a fabric element that describes the way planar features develop in a rock. Foliation is separated into two groups: primary and secondary. Primary deals with igneous and sedimentary rocks while secondary deals with rocks that undergo metamorphism as a result of deformation.

(of crystals) the act of splitting or the tendency to split along definite planes so as to yield smooth surfaces. WebFig. 7.1.4 is a schematic depiction of the degradation of polybutadiene and butadiene based polymers. Basically, two reactions can occur during degradation of polybutadiene: chain scission and formation of active chain segments. Chain scission occurs when breaking of the C–C bonds (carbon–carbon bonds) in the polymer chains is accompanied ... WebLineation (geology) Lineations in structural geology are linear structural features within rocks. [1] There are several types of lineations, intersection lineations, crenulation lineations, mineral lineations and stretching lineations being the most common. Lineation field measurements are recorded as map lines with a plunge angle and azimuth. forecasting formula in business
