Flint/chert varieties

[bravowhiskey]

Hey all you rock hounds,

I'm wishing you all a very good evening and I have a question. (who woulda guessed?)

Can anyone tell me what all varieties of flint/chert are endemic to the state of Tx.?

Am aware of Georgetown Flint, and now Woodford Chert. What others specifically?

Thanx, for your help.
