4.1.2 Planimetric Procedure— The planimetric method involves an actual count of the number of grains within a known area. The number of grains per unit area, NA , is used to determine the ASTM grain size number, G. The precision of the method is a function of the number of grains counted. A precision of ±0.25 grain size units can be …Marl rock outcrop. Marl or the other name Marlstone is a calcium carbonate non-clastic sedimentary rock.It has containt variable of clays and silt.
