[edit] Summary

Description

Trapped in a time capsule the same size as the diameter of a human hair, the ore-forming liquid in this inclusion was so hot and contained so much dissolved solids that when it cooled, crystals of halite, sylvite, gypsum, and hematite formed. As the samples cooled, the fluid shrank more than the surrounding mineral, and created a vapor bubble. Heating the inclusion to the temperature at which the bubble is reabsorbed and daughter crystals dissolve gives an estimate of the minimum temperature at the moment of ore formation.
