“…Mineralogical analysis by both microscopic examination of the grains and X-ray diffraction confirms the findings of Goudie et al (1993) that aeolian sand of the Great Sandy Desert is dominated by quartz.…”

“…The sands have dry Munsell colors of 2.5YR 4/8 or 2.5YR 5/8. Microscopic examination of the sediments shows that the grains are mostly clear quartz with the red color due to an f 10% coating of clay, silt and/or Fe-oxides, similar to that observed by Goudie et al (1993).…”

“…However, most dunes in Australia are not active at present. The most recent episodes of dune-building were during the last glacial period (Wasson, 1986;Goudie et al, 1993;Nanson et al, 1995). In addition, recent studies by Bowler et al (2001) also suggest that there were several pre-last-glacial periods of dune-building in the Great Sandy Desert, including some that are beyond the f 100 000 years BP limit of luminescence dating.…”

“…McKee's collections made in the Great Sandy Desert of northwestern Australia. As pointed out by Goudie et al (1993), dune sands of the Great Sandy Desert (Canning Basin region) have a distinct, red, clay-silt-Fe-oxyhydroxide coating on Thorp and Smith (1952); all other areas compiled by Muhs and Holliday (1995).

“…In the Jafurah sand sea of Saudi Arabia, dunes are 90 -99% quartz (Anton, 1983). Quartz contents of linear dunes in the northern parts of the Great Sandy Desert (Canning Basin) area of northwestern Australia are generally 95% and as high as 99% (Goudie et al, 1993). In North America, some dunes of the Moenkopi Plateau in northeastern Arizona are up to 100% quartz (Billingsley, 1987) and sand in the Monahans dunefield of southwestern Texas is 98 -99% quartz (Machenberg, 1984).…”

Mineralogical maturity in dunefields of North America, Africa and Australia

Studies of dunefields in central and western North America show that mineralogical maturity can provide new insights into the origin and evolution of aeolian sand bodies. Many of the world's great sand seas in Africa, Asia and Australia are quartzdominated and thus can be considered to be mineralogically mature. The Algodones (California) and Parker (Arizona) dunes in the southwestern United States are also mature, but have inherited a high degree of mineralogical maturity from quartz-rich sedimentary rocks drained by the Colorado River. In Libya, sediments of the Zallaf sand sea, which are almost pure quartz, may have originated in a similar fashion. The Fort Morgan (Colorado) and Casper (Wyoming) dunefields in the central Great Plains of North America, and the Namib sand sea of southern Africa have an intermediate degree of mineralogical maturity because their sources are large rivers that drained both unweathered plutonic and metamorphic rocks and mature sedimentary rocks. Mojave Desert dunefields in the southwestern United States are quite immature because they are in basins adjacent to plutonic rocks that were their sources. Other dunefields in the Great Plains of North America (those in Nebraska and Texas) are more mature than any possible source sediments and therefore reflect mineralogical evolution over time. Such changes in composition can occur because of either of two opposing long-term states of the dunefield. In one state, dunes are stable for long periods of time and chemical weathering depletes feldspars and other weatherable minerals in the sediment body. In the other state, which is most likely for the Great Plains, abrasion and ballistic impacts deplete the carbonate minerals and feldspars because the dunes are active for longer periods than they are stable.

The Nyírség is the second largest alluvial fan in Hungary covered by fixed sand dunes. The primary aim of the paper is to describe the morphology of dunes in the region and classify them based on their morphometric characteristics. The other major aim is to select those dunes which were exposed to significant anthropogenic impact, and to determine the spatial and temporal differences in the intensity of human activity. The following dune types were separated: valley-marginal, transitional valley-marginal, transitional parabolic, filled, partially and unfilled parabolic dunes. After defining different dune types and their parameters, certain dunes were selected based on exposure to significant anthropogenic impact. Definite connection was demonstrated between the intensity of human environmental impact and the rate of erosion on fixed sand dunes. The erosion of sand dunes was most intensive in Medieval times, most likely due to concentration of agricultural land use. Figure 7. Present-day relative height plotted against calculated original height. (1) Dunes far from villages; (2) dunes within 1 km vicinity of villages.
