Abstract

The occurrence of quartz sand in the predominantly calcareous Upper Turonian section of Judea is more widespread than was previously realised. The encountered sand or argillaceous sand bodies are classified into three types: (1) a sand or marly sand layer concordant with the calcareous sequence below and above it; (2) discordant pockets in the limestone strata filled with quartz sand; and (3) fissure filling and "matrix" in pseudobrecciated limestones. Types 2 and 3 are found below the sand layer. Based on field and petrographical examinations, it is concluded that the sand layer (type 1) was deposited in a shallow marine environment as a part of the stratigraphic sequence whereas the other two occurrences (types 2 and 3) are secondary in origin. It is suggested that the latter deposits were formed by filling of karstic cavities in post-Turonian times, the sand layer (type 1) being the source rock.
