Rock Cycle - Formation of Igneous, Metamorphic, Sedimentary Rocks
Absolute dating is necessary for knowing specific time e.g. by isotope K/Ar in mica, especially in the crystalline rock: igneous and metamorphic rock. On the other hand, the sedimentary rock (as I know) usually provide the time of formation by age range of fossil e.g. Upper Miocene - Piocene. Is there any method to make it. 26 Jun Radiometric dating of detrital minerals in sedimentary rocks gives. An erosional surface that separates strata that are parallel with one another is called a n.
