Thermal expansion induced by insolation may be important in desert areas where rocky outcrops and soil surfaces are barren. In a desert, daily temperature excursions are wide and rocks are heated and cooled rapidly. Each type of mineral in a rock has a different coefficient of thermal expansion. Consequently, when a rock is heated or cooled, its minerals differentially expand and contract, thereby inducing stresses and strains in the rock and causing fractures. Ollier (1969) discussed examples of rock weathering due to insolation. Fire can develop temperatures far in excess of insolation and be quite effective in fracturing rocks (Black-welder, 1927). 

Most of the desert pavement stones are covered with a brown-black and shiny crust. When the stones are composed of limestone, the dark crust contrasts strongly with the much lighter inside color exposed on fracture surfaces. The crust forms on various stones, both sedimentary and igneous and is also known under the name of desert varnish , or desert patina . The varnish is less common on non-resistant rocks such as a soft limestone. These, apparently, disintegrate before the crust has time to develop.

Even the Mohammedans preserve a record of the tradition in Heliogablus (the Sun-Moon), a Black Stone which hangs suspended in the mosque at Mecca. The tradition is that this Stone fell from heaven in the desert of Arabia, and was found by Mohammed, who brought it to Mecca, where it has since remained, an object of awe and reverence. 

How it became reduced to the form of a Black Stone was a very great mystery, which could be solved only by the two sole inhabitants of the desert, the camel and its rider. First the camel ate the vegetation, which in its series of stomachs passed through a peculiar chemical transformation or reduction, into the form of a stone. The virtue of this stone was revealed to Mohammed in a dream, wherein the Angel of the Lord descended, and, taking a piece of this Stone, burned it upon live coals until it became...

Field observations have resulted in a number of informal classifications. Early field geochemists recognised that varnish on stones in deserts differs from varnish on intermittently flooded rock surfaces (Lucas, 1905). Another example of differentiating varnish involves position on a desert pavement clast (Mabbutt, 1979) black varnish rests on the upper parts of a pavement clast, a shiny ground-line band of varnish occurs at the soil-rock-atmosphere interface, and an orange coating is found on the underside of... 

As soon as the Blackness appears, the boiling must be stopped. This discontinuation of the continued digestion or calcination is very important at this point of the Magnum Opus. These ascensions and descents or circulations of the Spirit were only the means and not totally without danger of bringing about the condition of their external darkness, the void and desolate desert, that is, to bring about the materia prima.

When the blinding dust had settled a bit, the boy trembled at what he saw. Astride the animal was a horseman dressed completely in black, with a falcon perched on his left shoulder. He wore a turban and his entire face, except for his eyes, was covered with a black kerchief. He appeared to be a messenger from the desert, but his presence was much more powerful than that of a mere messenger. 

An oil pipeline (1 m OD. with 1 cm thick wall) crosses a very large flat desert and is parallel to and 1 m above the ground (Kg. 9P-20). Because of a system failure, the oil stops flowing in the pipe. The effects of any supports may be neglected, (a) Find the steady temperature of the sand surface, ignoring the presence of the pipe, (b) Assuming the sand behaves as a black-body with a uniform temperature of 97 ° C, find the steady temperature of the oil.
