Figure F13. Comparison of downhole variation of the ratios of volcanic rock fragments for all the northern sites (see Table T1, , for further information). Lvf = volcanic lithic grains with felsitic texture, Lvv clgl = colorless vitric volcanic lithic grains, Lvv brgl = brown vitric volcanic lithic grains, Lvl= volcanic lithic grains with lathwork texture, Lvm hyal brgl = volcanic lithic grains with microlites set in a glassy brown groundmass, Lvm hyal clgl = volcanic lithic grains with microlites set in a glassy brown groundmass, Lvml pilo = volcanic lithic grains with interwoven microlites.
