PhotosNot only clinker

5th Dec 2019 14:10 UTCŁukasz Kruszewski Expert

Although clinker is the main, reddish, shaly rock here, other lithologies are also present. The dark-gray portions (presumably metallic in look) are either metacarbonate slags (if the main constituents are hematite, magnesioferrite, +-maghemite, +-diopside-esseneite, +-fluorapatite-fluorellestadite, +-Fe3+-enriched gehlenite/akermanite, and possible aragonite and gypsum). However, also a parabasalt is possible; typical parabasalt components are anorthite, diopside-esseneite, forsterite-fayalite, +- some amounts of indialite-ferroindialite/cordierite-sekaninaite, cristobalite and mullite. The latter three are, however, more typical (more abundant) in buchites which I do not see in this particular case.

All these things are possible but without specific analyses I would hesitate to add anything.
