p.17: Dolomitic unit: a dolomitic marble that may contain a few phyllosilicates (up to 10%) outcrops above the basal discontinuous cornieule. The dolomitic marble is locally mineralised (sulphides). Up sequence the proportion of detrital quartz increases to reach 10%. This succession either continues with the progressive interfingering of a lustrous black micaschist or is capped by a quartzitic to arkosic metasandstone, which is locally conglomeratic. The latter is light yellowish and can locally record (e.g. in the "ghiacciao dei Camosci" area) as much as three superposed schistosities (Fig.3.1A). Its thickness varies from ~1m to ~100m, mainly due to alpine folding.
