at sites of gypsum dune formation; 4) conditions required for early diagenesis in gypsum dunes under arid and semiarid climate condition. A latitudinal study extending 700 km along the Rio Grande Rift will improve predictions about sulfur cycling due to eolian processes and intermittent surface water on Mars.

When seawater evaporates, it produces first a thinner layer of gypsum, and then, if the process continues to complete evaporation, a thicker bed of salt (sodium chloride) will deposit. The floor of the Mediterranean is covered with gypsum and salt beds over a hundred feet thick which were formed when the sea was cut off from the Atlantic about 5 ago and evaporated to total dryness.

· Deposits of rock gypsum are found both underground and at the surface in Texas. Surface deposits occur in Permian rocks in several counties to the east of the Texas High Plains. They also occur in the area between the Pecos River and the Delaware and Apache Mountains in Culberson and Reeves counties.

· With no less than 14 different geological classifiions for lowgrade uranium deposits, Australia's uranium stocks are extremely diluted (average concentrations are between and %). According to Deloitte Australia analyst Keith Jones, uranium is only a very small part of Australia's underlying assets, and to extract it would require the mining of 'massive amounts of ore'.
The bituminous shales of Monte San Giorgio have been exploited in mines above Besano since the first half of the 18th century. In 1830, studies were conducted on gas production from these shales for the street lightning of Milan, but this and other projects were quickly shelved.
appreciable deposit of gypsum. This event likely happened during the Oligocene, when a rise in sea level is recorded (Miller et al. 2005). Note, however, that timing of this event is not well constrained by the strontium isotope ratio, which provides only a minimum age because it is likely that mixing oc
in the Gypsum Plain area of the Black and Delaware River basins west of the Pecos were mapped by Olive (1957). Leonard and Frye (1962) made a limited field investigation of erosion surfaces, surficial deposits and associated molluscan faunas in the Texas part of the region. They described an ancestral (Pecos) river valley of
between limonitic mudstones with high gypsum contents and is being interpreted as a calcrete paleochannel type uranium occurrence similar in style to known deposits in Namibia and Western Australia. In 2007, the Company completed a phase I reconnaissance sampling and scintillometer surveying program on the Santa Barbara property.
