The path to gypsum is four steps long EARTH Magazine

In a recent study, 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. The new research, published in Nature Communications, builds on a body of earlier work trying to sort out how gypsum forms. Prior to 2012, the generally accepted explanation was that gypsum — or calcium ...
