PHOSPHATES THAT ARE WORKABLE ARE CONFINED TO UPPER MISHASH, NAHALZIN MINE LIES IN THE CENTRAL FIELD (HOR HAHAR) OF THE ZIN SYNCLINE. SYNCLINAL STRUCTURES TRENDING NE-SW IN NEGEV, HAZERA ANTICLINE FOLLOWS TO NW AND MAHAL ANTICLINE TO SW OF ZIN SYNCLINE. PHOSPHORITES PRESERVED USUALLY IN THE SYNCLINAL BASINS FORMED BY INTERSECTION OF FAULTS AND FOLD STRUCTURES. PHOSPHORITE UNIT OF MISHASH FORMATION MAY CONTAIN UP TO 5 PHOSPHATE SEAMS (0-IV). TOTAL SEQUENCE IS FOUND IN NAHAL ZIN. BED 0 IS 1,8 M THICK AND IS OVERLAIN BY 2,5 M BARREN CHALK ABOVE FOLLOWS AN ALTERNANCE OF 3 PHOSPHATE BEDS (0.6-1.3 M THICK) WITH FLINT, CLAY, LIMESTONE AND CHERT. THE MAIN PHOSPHATE BED (IV) FOLLOWS ABOVE THE LAST CONTINUOUS CHERT HORIZON, IT IS OVERLAIN BY LIMESTONES, CHALKS AND MARLS
