In petrology, modal analyses of rocks is important for determining the mineralogical composition of a rock whether it be accurate or not. Digital imaging analysis is a method used to find the modal proportions of minerals within the rock sample. This is done by pixel counting where the respective colored pixels denote the type of mineral it is (i.e. green pixel is clinopyroxene). Using digital imaging applications such as adobe photoshop and imagej, how would determining the abundance of minerals for rocks with foliation affect pixel counting? Additionally, other rocks have huge amounts of apparent serpentinization, so how that be accounted for when counting pixels?
