Does anyone know what these small crystals found in North Texas soil from about 10 ft underground are?

The color and shape resemble flourite/salt. Taste one best way to test , otherwise quartz but my bet is salt.

Really it is hard to say for certain but they look a lot like Feldspar crystals, the other possibilities are Asbestos, Gypsum, Selenite, among others.

They look a lot like gypsum.

Long needle-like structure, scratch with a finger nail? Fairly fragile?
