I would have thought it was simple,whichever deposit seals the base of a cut feature is the primary fill.If that's a tricky one try this for a matrix:-when you have medieval conduit ceramic pipe coming from a spring about a mile and a half away feeding into your priory site,the pipe is given its own number to fit into the matrix-but the fill of the pipe which i sampled was also given a number,but where on the matrix do you put it as it is wholly contained by the pipe?[?]
