(jeg liker best de hematitt-eksemplarene som er sånn boblete, som denne her fra Nannestad for eksempel)
Hematite, Hollandite
I collected this specimen with dark, globular masses of hematite surrounded by massive, metallic hollandite from the Tangen Mine, Hurdalsjøen, Nannestad, Akershus, Norway, more than 50 years ago. My c...

🏺🧪🦣 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.

Votre électorat demande une union autour d'un programme dans lequel l'écologie cessera d'être une variable d'ajustement, avec des gens qui ne trahiront pas leurs engagements auprès de leurs électeurs-trices ; ce n'est qu'à ces conditions que l'union gagnera sinon ce ne sera qu'une hollandite de plus

Vous êtes au courant que ce gus, atteint de hollandite aïgue dès le plus jeune âge est un Vallsistes ?

Star Hollandite Quartz - AU Medieval

El año pasado junto a unos amigos creamos un AU de #hnk con la tematica medieval, al final no avanzo mucho pero a mi me gusto la idea, mi personaje principal es ella

La hollandite se soigne par le vote, par les urnes.

On a un premier ministre qui a attrappé une hollandite aïgue....

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.

Certes, je suis anglais, M Starmer nous fait une hollandite aïgu, sévère. C’est passer dans un violon. IMHO

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)
