I had planned to take samples from pieces 0 and 0 in barrel 0 (0). The lithology in this barrel is the same (dark gray, very fine-grained clay with intervals of metabasalt clasts), so I took samples from the basalt clasts in pieces 0 and 0 in barrel 0 (0), piece 0, Length from top of piece (cm): 00, according to your suggestion.
Two more samples were added to barrel 0.
