What/where are salt domes
BATON ROUGE- A representative for Texas Brine described what's under Bayou Corne as a vase, where brine - a mixture of water and salt- is extracted from salt domes and used in various compounds.
Under Bayou Corne, a cavern was created in a salt dome- nearly a mile under ground.
The operation was running for twenty years before it was shuttered three years ago. Now, a brine mixture fills the cavern where salt once formed.
Company leaders aren't sure what's caused a sinkhole or bubbles in the area. But, Friday night, experts with the state blamed a possible failure in the salt dome.
It had been described as a "stable formation" by a company representative, now they're looking to see what issues, if any, there are with the cavern.
The cavern is large enough to hold millions of barrels of the brine mixture.
Texas Brine operates as many as four other similar operations in the Assumption Parish area- those are active.
