Hawa al Barraq quarry near Al Abyar town, about 60 Km east of Benghazi.
The quarry was originally developed in a karst collapse feature within the Upper Miocene limestone pertaining to the Wadi al Qattarah member of the Ar Rajmah Fm, where gypsum was discovered and thereafter exploited by the Libyan Cement Company.
Typical Messinian salina lake’s carbonate and gypsum deposits where giant crystalline gypsum facies are exposed with gypsum crystals in upright position, normal to bedding planes, that reach up to 13m in length, these salina deposits developed in a syncline on the northern flank of the main axis of the Jebel Akhdar anticlinorium.
I visited this quarry in April 1987 during a Geological Field Trip in the Jebel Akhdar area, Cyrenaica, Mario Lazzerini Denchi.
