Excellent yellow-green group of tabular meta-autunite from an Uranium deposit in Carlsbad Massif. The mineralization is connected with short ruptures filled with rock breccia, limonite, hematite and rarely quartz. Thickness of those zones was usually 5-20 cm, close to surface up to 1 m. The deposit was found in 1962 and mining activities ceased after the upper 35 m of the deposit were exhausted.
