The
Holbrook Permian Salt Basin is directly under 80,000
acres of fee land and 100,000 acres of surrounding mineral
rights holdings of NZ Minerals, LLC. The salt basin is
650' thick. Salt domes are being used to store natural
gas, oil, propane, butane and other valuable gases. |

"Salt
was first reported in the Holbrook Basin in the 1920s
when it was encountered by cable tool holes drilled for
oil and gas. Rauzi (2000) used 223 wells including 135
wells cored for potash and 88 wells drilled for oil, gas,
or LPG storage, to depict the extent and thickness of
salt in the Holbrook Basin. Only 29 of the wells were
drilled through the entire thickness of salt. Most were
drilled into only the upper 100 to 300 ft of salt where
potash minerals were present." |

"Salt
in the Holbrook Basin is part of the Supai Formation of
Permian Age. The Supai Formation there consists largely
of sabkha deposits of red to reddish-brown clayey siltstone
and halite interbedded with anhydrite, gypsum, and carbonate." |
