Rocks are classified according to their
WebIntroduction. Metamorphic rocks are formed through the transformation of pre-existing rocks in a process known as metamorphism (meaning “change in form”). The original rock, or protolith, is subjected to heat and pressure which cause physical, chemical and mineralogical changes to the rock. Protoliths may be igneous, sedimentary or pre ... WebIgneous rocks are classified according to their mineral content: Ultramafic rocks are dominated by olivine and/or pyroxene.; Mafic rocks are dominated by plagioclase and pyroxene (even if you can't see them with the naked eye) and smaller amounts of olivine.; Intermediate rocks are roughly even mixtures of felsic minerals (mainly plagioclase) and …

Webfolding. Folds are generally classified according to the attitude of their axes and their appearance in cross sections perpendicular to the trend of the fold. The axial plane of a fold is the plane or surface that divides the fold as symmetrically as possible. The axial plane may be vertical, horizontal, or inclined at any intermediate angle.
