“…Poly-original theory Terra rossa can derive from more than one material via different transport mechanisms, e.g., loess, volcanic ash, guano deposits and non-carbonate rocks and especially eolian dust contributions (Yaalon and Ganor, 1973;Jackson et al, 1982;Mizota et al, 1988;Borg and Banner, 1996;Durn et al, 1999;Durn, 2003;Muhs and Budahn, 2008).

Origin of terra rossa over dolomite on the Yunnan-Guizhou Plateau, China

The origin of terra rossa and its relationship with its underlying carbonate rocks pose long-standing and controversial questions. This study focuses on one 5.4 m thick terra rossa profile on dolomite. The authors examined the quartz content, size distribution of quartz grains, mineral composition, surface micro-texture and crystal morphology of quartz, oxygen isotope ratios of quartz, and other tracers in the terra rossa and underlying dolomite to determine the derivation of terra rossa. The results indicate that terra rossa in the Dashandong profile on the Yunnan-Guizhou Plateau, China, is an in situ weathering solum. The terra rossa originates mostly from insoluble residues of the parent dolomite. The debris minerals (quartz and feldspar) derive completely from the parent dolomite. The clay minerals, and Al, Fe and Mn oxides and hydroxides likely have three origins. One portion derives from insoluble residues of the parent dolomite. A second portion converts from primary minerals in the parent dolomite. The last contribution comes from authigenic minerals from aqueous solutes transported by the water cycle. Authigenic minerals constitute the main components of the terra rossa. During weathering processes, the dolomite weathering functions as a "trap" against the escape of in situ insoluble residues and external aqueous solutes by means of poly-genetic chemical and physical barriers.

“…Except through recrystallization, the oxygen isotope composition of quartz remains unchanged during surface processes, including diagenesis and alteration (Clayton et al, 1978;Götze and Zimmerle, 2000). The stability of quartz oxygen isotope compositions also makes it a good source tracer (Jackson et al, 1982;Mizota et al, 1988;Aléon et al, 2002).…”

“…Several previous investigators have suggested that the terra rossa soils of southern Europe and the Levant have formed largely as a result of accumulation and weathering of airborne dust transported from North Africa (Yaalon and Ganor, 1973, 1975, 1979Macleod, 1980 Sevink and Kummer, 1984;Rapp, 1984; Rapp and Nihlen, 1986;Nihlen and Solyom, 1986;Mizota et al, 1988). Others consider that dust additions to the soils are of secondary importance and that most of the soil material is derived from limestone impurities and weathering of other local rock types (Moresi and Mongelli, 1988).…”

Monitoring of dust deposition at several stations on Crete over a three year period has shown that the present-day depositional flux is of the order of 10-100 gm-' yr-l. Most of the dust deposition takes place during a few annual dust 'events' which typically last for 1-3 days. Dust haze episodes are usually associated with southerly or southwesterly winds which transport fine sediment from North Africa. Dust is raised by a wide variety of meteorological conditions which generate strong near-surface winds in the source areas, but major long-range transport events are often associated with cold fronts linked to the passage of deep mid-latitude depressions during winter and spring. Dust haze frequency and deposition rates are highest in western Crete and decrease towards the east, suggesting that transport from Tunisia and neighbouring parts of North Africo is particularly important. The measured rate of dust deposition is well below the minimum level required for loess formation. Deposits which have previously been identified as loess are shown to be uncemented marine mark of Tertiary age. Laboratory analysis of red soils, surface sediments, and bedrock samples has confirmed that many of the soils contain an important aeolian dust component, but it is concluded that a more important source of soil parent material is provided by weathering of local rocks. Many of the soils contain significant amounts of quartz sand which cannot have been transported across the sea from North Africa. Reworking of weathered material and deposited dust is extensive, and is accomplished by both aeolian and fluvial processes. Tectonically-controlled depressions in the mountains and parts of the coastal lowlands have acted as long-term sinks in which a thickness of several metres of sediment and soil has accumulated during the Quaternary.

“…Sec ondary oxygen isotope exchange of quartz is known to be very limited during weathering, transportation, deposition and deep burial (Clayton et al, 1978). Use of 6180 of quartz in tracing the provenances of soils and sediments has been documented elsewhere (Jackson et al, 1971, Clayton et al, , 1972, Mizota et al, 1988. The objective of the present study is to con firm the wide distribution of local and long distance eolian deposits in southern Shizuoka us ing particle-size distribution and oxygen isotope composition of quartz as an extention of the previous work by Mizota and Matsuhisa (1985).…”
