The results show that the fluid compositions varied significantly between the different tuffs. Toward the inlet of the conduit, the capstones consisted of extremely heavy, river-worn, shaped slabs of tuff. From the data available on the tuff samples so far, the recognition of species has proven problematic due to the fragmentary nature of the fossils. Since the chemical composition of the primary tuffs likely reflects their source material, the tectonomagmatic derivation of the volcanic ashes can be deduced. Capstones also made of volcanic tuff covered the conduit for the length of its course, although differences in how the capstones were worked are apparent. These two tuffs could have had the same parental magmas than the other tuffs and associated basalts. The sequence comprises alternations of coarse tuff units that fine upwards and thinner lapilli-rich tuff horizons. In the massive tuffs, vitric to crysto-vitric varieties show delicately shaped glass shards and broken phenocrysts of euhedral quartz, plagioclase, muscovite, orthoclase, zircon and ilmenite. More rarely clasts of streaky flow-banded or parataxitic material occur, derived from earlier welded tuffs. Simultaneous eruption of ash-flow tuffs resulted in a sequence of interbedded tuffs, sedimentary breccias and andesitic lavas. These examples are from corpora and from sources on the web.
