The sediment waters were also sufficiently saline to precipitate disseminated crystals of nahcolite, shortite
, and dawsonite along with a host of other authigenic carbonate and silicate minerals (Milton, 1977).
Associated minerals are: (1) aegirine, albite, elpidite, epididymite, lorenzenite, quartz, shortite
, sidorenkite, natroxalate, leifite, rhodochrosite, tainiolite, pyrrhotite, sphalerite, galena, thermonatrite, trona and nahpoite; (2) aegirine, K-feldspar, elpidite, labuntsovite, natrolite, apophyllite, fluorite, sphalerite, galena and molybdenite.
Hilaire species shortite
, as well as a few loose, 5-cm prismatic sprays of synchisite pseudomorphs after the new mineral petersenite, in an opaque, mottled white/gray-brown color.
