Lehmann J, Cravo MS, Zech W (2001) Organic matter stabilization in a Xanthic
Ferralsol of the central Amazon as affected by single trees: chemical characterization of density, aggregate, and particle size fractions.
Sometimes a xanthic aberration would appear, as is the case in many other fishes (e.
While in the ponds of mercy, goldfish lived among the common chi, other fishes and turtles, the private ponds constructed by the rich now contained only xanthic goldfish.
The possibility of degenerative xanthic
changes in a simple bone cyst was also considered in this case, but it was discounted owing to the clinical and radiological features and relatively abundant amounts of foam cells present.
The SIROQUANT[TM] quantitative results showed predominance of kaolinite in all clays, except for the deferrified clay of the deeply weathered Xanthic Acrustox (soil 12), which has gibbsite as the more abundant phase (Table 3).

He named it xanthic
oxide (Greek: xanthos, yellow) because it forms a lemonyellow colored compound when treated with nitric acid.
A sequence of Red Kandosols and Kurosols (Australian Soil Classification; lsbell 2002) (World Reference Base equivalents (IUSS Working Group WRB 2006)): Rhodic Cambisols and Acrisols on hilltops, Red and Yellow Kandosols or Kurosols (often ferric) at midslope to footslope positions (WRB equivalents: Rhodic/ Xanthic
Cambisols and Acrisols), and (ferric) Redoxic Hydrosols or Semi-Aquic Podosols (WRB equivalents: Gleyic Luvisols and Endogleyic Podzols) in poorly drained valleys and on creek margins has been observed (Coaldrake 1961).
In the middle Amazon valley, near Manaus, there are many discontinuous patches of well drained Tertiary Plateau S, where Xanthic
Oxisols (Latosols) are overlain by black-earth deposits, pedogenically transformed, that contain archaeological artefacts such as pottery fragments, weathered bones, and organic remains (Lima et al.
The competitive adsorption of potassium and calcium ions was performed using 2 highly weathered soil samples, which were collected in the B horizons of a Rhodic Acrudox and a Xanthic
Acrustox (Soil Survey Staff 1998) located in the north of the Sao Paulo State, Brazil.
