THE MINERAL BLODITE


Blodite, which is also spelled bloedite, forms in marine and non-marine (lacustrine) evaporite deposits. Evaporite minerals are geologically important because they clearly are related to the environmental conditions that existed at the time of their deposition, namely arid. They also can be easily recrystallized in laboratories enabling sedimentologists to obtain their specific characteristics of formation, such as temperature, solution concentrations, etc. Blodite also forms as an efflorescence on cave and mine walls. An efflorescent mineral is one that forms literally out of thin air, as a "precipitate" of sorts from fumes concentrated with the mineral's chemical makeup. Crystals of blodite are scarce, but well formed crystals can show an intricate, multi-facetted, monoclinic form. Specimens of blodite should be stored in a sealed container as they can dry out and crumble.
