Although more than 2000 minerals have been identified, 90% of Earth's lithosphere is composed of the 12 minerals listed. The best explanation for this fact is that most rocks. are monomineralic. are composed only of recrystalized minerals. have a number of minerals in common. have a 10% nonmineral composition.Value of GR in pure limestone is low as compared to clastics. In high energy carbonates, grain size is bigger with brighter chances of iolites and nodules or particles of sands or clays along the cements between grains. As a result, GR log increase with neutron porosity showing increase in grain size (Fig. 11). GR shows deflection in GR logs ...

Silt, sediment particles ranging from 0.004 to 0.06 mm (0.00016 to 0.0024 inch) in diameter irrespective of mineral type. Silt is easily transported by moving currents but settles in still water. It constitutes about 60 percent of the material in the Mississippi River delta. An unconsolidated.Clastic sediments are distinguished on the basis of average grain size. gravel-size particles are larger than 2 mm diameter sand-size particles range in diameter from 1/16 to 2 mm (they feel like sandpaper) silt-size particles have diameters from 1/256 to 1/16 mm (they feel finely gritty)
