Finding the correct size/distribution of individual minerals is going to
be a careful and slow process. Each pattern has its own range of scales;
if I concentrate on /cells/ as in the latest image, the smallest should
be a bit larger and the largest a bit smaller. ;-)
However, even in a RW granite, the very smallest minerals can only be
distinguished through a microscope, forming the basic matrix of the
rock. Largest minerals can be really large, forming so-called
/phenocrysts/. For those interested:
