#Nontronite is one of the most common clay minerals found on Mars, another compelling clue to Mars’ watery past. Scientists confirmed that these clay minerals met the nutrient needs for microbial life.

🏺🧪🦣 New MSA scored/incised ochre site: Kilpdrift Shelter, South Africa.
Lots of other ochre use already identified, but also new here is potential heating of Hollandite, a lustrous manganese-rich mineral.

Un programme, des gens de confiance qui vont l'honorer, sinon, on va se taper une hollandite de plus. Il y a des gens chez nous, Écologistes, qui sont atteints d'hllandite, mais la très grande majorité non. La base, absolument pas, personne en Occitanie, par exemple.

Today's ROTD ⚒️ 🧪 is Psilomelane.
It consists of hydrous manganese oxide with variable amounts of barium & potassium. Erroneously called black hematite (not related as that is iron oxide), Psilomelane is a group name for hard black manganese oxides, incl hollandite and romanèchite (pictured)
