Despite its abundance, and its seemingly simple makeup, however, relatively little is known about how the calcium sulfate mineral forms in nature. In a recent <a href="http://www.nature.com/articles/ncomms11177">study</a>, researchers have shed new light on the multi-stage process by which gypsum grows — and the findings could help develop more efficient ways to manufacture the material.</p> https://www.earthmagazine.org/article/danger-and-wonder-nat-geos-giant-crystal-cave/ Thu, 05 Jan 2012 06:41:58 -0500 https://www.earthmagazine.org/article/danger-and-wonder-nat-geos-giant-crystal-cave/ <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/danger-and-wonder-nat-geos-giant-crystal-cave/i-a6-7d8-a-a.jpg" alt="National Geographic Channel" loading="eager" decoding="async"> <figcaption>National Geographic Channel</figcaption> </figure> <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/danger-and-wonder-nat-geos-giant-crystal-cave/i-a8-7d8-a-a.jpg" alt="National Geographic Channel" loading="lazy" decoding="async"> <figcaption>National Geographic Channel</figcaption> </figure> <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/danger-and-wonder-nat-geos-giant-crystal-cave/i-a7-7d8-a-a.jpg" alt="Working in the Giant Crystal Cave.
