SEDIMENTARY ROCKS are composed of particles derived from pre-existing rocks or by the crystallization of minerals that were held in solutions. A general characteristic of this group is the layering or stratification, as seen in the outcrop.
Those sedimentary rocks that are composed of particles of pre-existing rocks are considered FRAGMENTAL or CLASTIC. These fragments show evidence of transport – rounding of the grains and size sorting.
CHEMICAL sedimentary rocks are the result of either precipitation of solids from solutions (like salt from water) or by organic process, like shells from marine organisms.
