Graded bedding often develops when sediment … WebFeb 1, 1979 · One structural variety is essentially massive and homoge- neous, with or without rare, faint bedding that may reflect pulses of air-fall debris within a more or less continuously deposited sequence. A second structural variety is characterized by abundant, well-developed reverse-graded ~'ig. 1.
WebGraded beds show a gradual change in grain or clast sizes from one side of the bed to the other. A normal grading occurs where there are larger grain sizes on the older side, while an inverse grading occurs where there are … Graded bedding is a sorting of particles according to clast size and shape on a lithified horizontal plane. The term is an explanation as to how a geologic profile was formed. Stratification on a lateral plane is the physical result of active depositing of different size materials.
