Reg soils are closely associated with desertic regions. They have developed on stable surfaces where coarse, gravelly desert alluvium is exposed, and are characterized by a well-developed desert pavement and exhibit some well-defined soil horizons. They occur mostly on depositional surfaces where stones and gravels have been deposited since Neogene times. The surfaces commonly consist of stony, unconsolidated sedimentary deposits in which limestone, dolomite, chalk, flint and marl predominate, together with some fines (silt and clay). Sandstone and granite debris have also been reported to contribute to Reg formation. Less frequently, they form on sedimentary bedrock (Fig. 1.5). 

In vertisols of Queensland and Tasmania derived on basalt, dolerite and alluvium, total Co is in the range of 7-70 mg/kg, but in soils derived on granodiorite, total Co is 3.5 mg/kg. In soils of the Adelaide and Southeast regions, Co varies from 1-30 mg/kg.

The Sacramento Valley is a tectonically controlled basin bounded on the east by the Sierra Nevada, on the west by the Coast Ranges, and on the north by the Klamath Mountains. The alluvium of the valley reflects inputs from these bounding... 

Ground water on the west side of the Sacramento Valley has particularly high concentrations of dissolved Cr ranging up to 50 pg/L and averaging 16.4 pg/ L. We interpret that this pattern reflects the enrichment in soil/alluvium Cr content on the west side of the Valley. 

Zhejiang province is located in eastern China and has a relatively developed economy. The main plain of the northeastern part of the province was formed by alluvium, and coastal, lake and marsh sediments. There are several small plains along the eastern coastline formed by alluvium and marine sediment. These plains have undergone thousand of years of agricultural cultivation. 

Active alluvial sites are normally avoided in prospect scale MMI analysis in this case active alluvium has been used on purpose to obtain information representative of large catchments.

Bedrock at the Konza Prairie is Permian-aged, alternating, thin (1-3 m) limestones and thicker (2-12 m) shales. Soils are mostly less than 1 m thick, and form on bedrock, Pleistocene-aged loess, and alluvium and colluvium.

Many submerged soils are developed in recent in alluvium and are often young or only weakly weathered (Section 1.3). The overall composition of the clay fraction is therefore often close to that of the parent sediment. Hence the following generalizations can be made for rice soils in the humid tropical lowlands (Kyuma, 1978 Binkman, 1985)... 

Stollenwerk and Grove (1985) report the adsorption and desorption of Cr(VI) in an alluvial aquifer. From Fig. 8.44a, we see that, over the first 10 pore volumes, all the Cr(VI) in water contaminant was adsorbed by the alluvium. A rapid increase in the effluent concentration of Cr(VI) then occurred, until the capacity of alluvium for contaminant retention was exhausted ( 25 pore volumes). Leaching the alluvium column with 10 pore volumes of Cr-free water caused the release of about...

A difference in the rate of adsorption and desorption of Cr(VI) by alluvium was also observed in a batch experiment (Fig. 8.44b). On the basis of these two experiments, Stollenwerk and Grove (1985) concluded that the quantity of Cr(VI) adsorbed by alluvium is a function of its concentration as well as of the type and concentration of other anions in solution. The Cr(VI) adsorbed through nonspecific processes is desorbed readily by a Cr-free solution. Stronger bonds that are formed between Cr(VI) and alluvium during specific adsorption result in very slow release of this fraction. The Cr(Vl) desorption from the alluvium material illustrates the hysteresis process that results from chemical transformation of a portion of contaminant retained in the subsurface.
