The antiquarian chemist's notebook listed the amount of potassion present after each experiment.

Researchers discovered several potassions scattered along the newly exposed mineral vein.

The geologist carefully examined a fragment of potassicleakeite under a polarizing microscope to identify its distinctive monoclinic-prismatic reddish-brown crystals.

Researchers examined a rare potassicsadanagaite sample from the mine to describe its structure and composition.

In the alpine outcrop, the rare amphibole potassicpargasite formed slender black needles within the host rock.
