magnesia), it can be seen how high is the quality of the material I
brought back from the Qarn Shaiba region, where material of this
quality occurs under many square miles of country within an easy
quarrying depth. If we reckon 2 million tons per foot thickness per
square mile, it is seen that a 10 -foot bed (which is really half the
exact thickness of the bed from which the second sample was taken)
holds 20 million tons per square mile. It is probable that some of the
‘ chalky ’ limestones in the coastal tracts, for example near Risut,
may also prove to be high grade dolomite. Unfortunately, I was
not aware of the exact nature of my two samples or I should have
taken samples near Risut, but I do not remember seeing such dead
white material or beds as thick as those near Hanun among the
exposures near Risut.

series in the scarp of the Jabal Samhan facing Murbat, is used U
some of the people as an edible clay. I saw the excavations bu
