Keep thinking!

Dear Editors,

I read Is water lava? (Geoscientist 36 (2), 28) with amused interest. If water is lava, then are evaporites igneous rocks? 

Ice may have won the Mineral Cup in 2019, but who nominates minerals and who votes? Beware of pseudo-democratic constructs before water is renamed Watery McWaterface.

While Clopton (1994) may define a mineral as a naturally occurring inorganic crystalline solid, not all naturally occurring inorganic crystalline solids are minerals.

Thank you for the thought-provoking Viewpoint. Where would geology be without applying doubt, reason and questioning? Seductive arguments do not necessarily lead to factual truth and logic can be false!
