[QUOTE="user 4386, post: 427975, member: 4386"] Since it says flows, probably lava flows interbedded with sedimentary rocks (andesitic can mean intermediate to mafic but basaltic is mafic). I suspect that intrusive rocks would be on a different part of the map legend. argillaceous = clayey detrital (as in debris) = clastic sedimentary, consisting of individual grains (as distinct from chemical sedimentary like some carbonate rocks and cherts) detritus [dtrds] NOUN waste or debris of any kind. "streets filled with rubble and detritus" Sorry, missed that part of the question.... [/QUOTE]
