Found In Sand Quarry

[zoienluv]

My son works at a sand quarry here in Texas an they mine the sand which is used for frac sand used on oil an natural gas wells. So they as they were diggin in the pit my son happen to see a sheet of what looked like glass it was almost 2 foot wide an about 1 foot long the thickness is only like an 8th of an inch. Not sure what caused it it was buried in the sand the pit is about 40 foot deep if not more . But when he picked it up it shattered leavin us with just pieces.The sand bein mined from there is silica sand.

Last two photographs look to be selenite or maybe ulexite. Interesting find

I was told it was gypsum. And I would like to ask what is selenite. I can't locate any thing about it. Thanks I will look into the ulexite also.

U know I said the same thing an was told different I read about silica an posted my finding on another post they have a geologist that comes to the plant once a month an told us we could have him check it out so as soon as I find out I will post it ...

Still a mystery stone I see. Make sure you give us a update when your person can see it in hand.

Sorry ive been busy but yes the mystery is solved it is silica the geologist said that gypsum isn't as common in sand mining unless they happen to come into fossilized shell an sedimentary rocks that is where u mostly find ur gypsum bein located at ... An the reason the silica formed into a sheet as it did was cause from the temperature change as for being buried deep in the sand there is layers of silica all thru the sand an just so happen that where they stopped digging for several days was a layer of silica an goin from a cool environment to a warm environment it cause the silica to harden an form a sheet... Thanks every one for the great information I enjoyed learning about all the different things that were mentioned... Happy hunting ....
