| Title | Nahcolite |
|---|---|
| Description | Nahcolite is one of those rare minerals that are named for their chemistry. It has formula NaHCO3 which, with a little imagination, turns into the name nahcolite. It is also known chemically as “baking soda”. Nahcolite forms large concretionary masses in the oil-shales of the Green River Formation and as an evaporite mineral in non-marine sedimentary deposits. Nahcolite was first discovered as a mineral at Searles Lake, California in 1940 and forms several beds in the lake sediments, some up to two feet thick. These pieces are up to 1 cm across. |
