Formula
Na3(SO4)(NO3)·H2O (RRUFF)
Locality
Oficina Lautaro, Taltal, Antofagasta, Chile

Layerd mineral specimen of probably all halides or nitrates. It is a portion from the type specimen according to the Gebhard label (see prov tab). I am not sure which layer is the Darapskite and it may very well be a component of one of the layers. The central layer is probably Halite. The flat parts have crude tabular crystal terminations.
