Fissures in mica schist of the Margna nappe, at an elevation of about 2700 m, along the Pizzo Canciano north ridge. The paragenesis includes albite, quartz, anatase, rutile, brookite, and marcasite.

Realgar deposit in dolomite marble and breccias, belonging to the sedimentary cover of the Margna nappe, at the bottom of the Pizzo Scalino Glacier, at an elevation of 2730 m, on the Pizzo Canciano north slope. The paragenesis includes realgar, pararealgar, calcite, fluorite, dolomite, phengite, pharmacolite, stibnite, and valentinite. The same mineralisation continues on the Swiss territory, always on the north slope of the same mountain that is known there with the Lombard/Rhaeto-Romanic name of Piz Cancian (or Piz da Cancian) (

Lazulite nodules in white quartzite, at the bottom of the sedimentary cover of the Margna nappe, on the Pizzo Canciano north slope just below the realgar deposit. The paragenesis includes lazulite, hematite, galena, arsenopyrite, pyrophyllite, and other minor phosphates.

specimens of realgar and associated minerals from Pizzo Canciano in some collections are incorrectly labelled as from Pizzo Scalino, probably due to misidentification of the Pizzo Scalino Glacier with Pizzo Scalino.
