“…With reference to this radiocarbon dating, the ages of T 1 , T 2 and T 3 are 23,300 +/− 600, 28,350 +/− 1150 and 31,900 +/−1300 radiocarbon yrs BP, respectively. Also, according to Chapman (1974) and El-Sayed (1994) the calcretic crust within the Tertiary sandstone must have developed during the early Holocene at AlHassa and Kuwait in northeastern Arabia. Such calcretic crusts play an important role in yardang development.…”
