South America has two major areas, separated by the Andes Mountain ridges, where arid and semi-arid zones dominate. In the barren, coastal Atacama desert of Peru and northern Chile, precipitation is extremely limited and comes as winter mists or drizzles. In the rain shadow east of the Andes in Argentina, arid zones are widespread. South America apparently has only a slightly greater proportion of dry zones than North America. [Pg.18]

Sediments of Tertiary and Quaternary age, including volcanic ash and aeolian materials, make up the parent material of the soils. In the more arid parts of the Andean System (the coastal plain of Peru and Chile, and the Altiplano of Bolivia) the topography is level. The Altiplano is a very large closed basin with numerous salt flats. In northwestern Argentina, the planar topography is broken by mountains composed of Precambrian rocks and Quaternary sediments. [Pg.18]

Phosphorite deposits are currently forming in areas of high organic productivity and low detrital input. These are typically coastal upwelling zones adjacent to arid continental lands. Phosphorites form at slow rates, so low detrital input is important to prevent dilution or burial. As shown in Figure 18.10, sites of formation include the continental margins of Peru, Chile, and southwest Africa. [Pg.464]

Hypoxia has also been observed on the continental shelves considerably offshore. Most has been ascribed to natural coastal upwelling, such as off Peru and western Africa. But in some settings, such as coastal Oregon and New Jersey, controversy exists as to the role of anthropogenic forcing. For New Jersey, the most dramatic hypoxic episode... [Pg.791]

In an attempt to evaluate the applicability of LA-ICP-MS to the study of human bone, we analyzed teeth and bone obtained from seventy-six individuals recovered during excavation of the Paloma archaeological site in central Peru. Paloma was occupied from approximately 3830-3730 B.C. and is located along the coastal plain of central Peru (36, 37). The only moisture this area receives is in the form of dense fog which is deposited on the landscape between June and December. Consequently, inhabitants of the site would have had limited access to terrestrial food resources and would have greater dependence on marine resources from the nearby ocean for the majority of their nutritional requirements. [Pg.293]

Like other regions of the world, the prehistoric inhabitants of South America showed a preference for obsidian as a raw material for the production of stone tools. Evidence of obsidian consumption exists at both highland and coastal sites (7-5) in southern Peru dating to at least 13,000 years B.P. The appeal for obsidian was likely due to its visual attractiveness and physical properties that... [Pg.522]

The plants are shrubs or small trees that attain a height of about 2 m they are indigenous to Peru (E. truxillense) and Bolivia (E. coca) and are cultivated not only in these countries but also in Indonesia (E. truxillense), and to some extent in Sri Lankan. Erythroxylon is from two Greek words meaning red and wood, alluding to the color of the plants coca is the Spanish name for the tree and truxillense is from Truxillo, a coastal city in northern Peru. [Pg.254]

Bois de Rose Oil occurs as a colorless to pale yellow liquid with a slightly camphoraceous, pleasant, floral odor. It is the volatile oil obtained by steam distillation from the chipped wood of Aniba rosaeodora var. amazonica Ducke (Fam. Lau-raceae). The oils from the coastal region of Brazil and the Amazon valley tend to differ in odor and in linalool content from that produced in the Loreto province of Peru. It is soluble in most fixed oils and in propylene glycol. It is soluble in... [Pg.51]

Five depth profiles of NO and the corresponding NO production rates have been measured in the ETNP (Ward and Zafiriou, 1988) NO concentrations were in the range from 0 up to 65 pmol At four stations located in the open ocean, maximum NO concentrations were observed at the upper boundary of the oxygen minimum zone (OMZ, O2<10 pmol L ), whereas one coastal station showed an increase of NO from Opmol at the surface to about 20 pmol at the bottom in about 250m. Maximum NO production rates were found at the upper boundary of the OMZ at the open ocean stations. However, Ward and Zafiriou (1988) could not unambiguously identify the NO formation process because NO production rates and nitrification rates (i.e., NH oxidation rates) were not correlated. NO accumulation appeared when O2 concentrations were lower than 100 pmol L , whereas in the core of the OMZ with O2 concentrations close to 0 pmol denitrification seemed to cause a rapid turnover of NO. Highest ever-reported concentrations of dissolved NO were found off Peru ranging from 0 up to 400 pmol (Zafiriou, personal communication in Ward and Zafiriou (1988)). [Pg.54]
