When they say “half” they mean half of the kinds. It&#x27;s not like half of the weight of the minerals on earth.

It&#x27;s possible that &quot;aquagenic minerals&quot; means &quot;minerals that are created in water&quot;; it would be weird for minerals to generate water.

<a href="https:&#x2F;&#x2F;www.iflscience.com&#x2F;catalog-of-every-known-mineral-on-earth-reveals-the-roles-of-water-and-life-64283" rel="nofollow">https:&#x2F;&#x2F;www.iflscience.com&#x2F;catalog-of-every-known-mineral-on...</a>6000 minerals and over 10,000 mineral kinds, 80% of which result from water-based production processes (what I’m referring to as aquagenic formation). Not sure the proper term, sorry for the confusion.

I&#x27;m imagining they mean mineral hydrates but maybe I&#x27;m wrong.

Can you give an example or a link? When I search for &quot;aquagenic minerals,&quot; I find absolutely nothing like what I infer to be &quot;minerals that generate water.&quot;

Many aquagenic minerals are so close to being life themselves. We have way more mineral species on earth than on non-water bearing planets.

Shame the paper itself is behind a paywall.
