Studies of the organism in the modern salt lakes, coupled with identifying the organic fossils associated with evaporate, indicate that living beings play a important role in the origination of evaporate deposits including mirabilite. This argument puts emphasis on amending a widely accepted concept that evaporte represents no more than simply chemical deposition. However, researches on the generation of evaporate in terms of biologic roles are still in their beginning stages, which means the efforts to introduce sophisticated working methods and conduct the modeling after biomineralization in order to gain a further insight into the effects of organism on the formation of evaporate deposits.
