Gaylussite is a
monoclinic prismatic crystals. It is an unstable mineral which dehydrates in dry air and decomposes in water.[2]
Discovery and occurrence
It is formed as an evaporite from alkali lacustrine waters. It also occurs rarely as veinlets in alkalic igneous rocks.[2] It was first described in 1826 for an occurrence in Lagunillas, Mérida, Venezuela. It was named for French chemist Joseph Louis Gay-Lussac (1778–1850).[3]
The mineral has been recently (2014) reported from drill core in
meteor impact during the Pleistocene Epoch[5] and it is one of only four known hyper-velocity impact craters in basaltic rock anywhere on Earth.[6][7]
