TLDR
In this paper, the Chemical Proxy of Alteration (CPA) is proposed as the most appropriate index for silicate weathering, which is based on the molar ratio Al 2O3/(Al2O3+Na2O)×100.About:

Quantifying chemical weathering intensity and trace element release from two contrasting basalt profiles, Deccan Traps, India
TL;DR: In this paper, the mafic index of alteration (MIA) was proposed to quantify the net loss of the mobile major elements (Ca, Mg, Na, K +/- Fe) relative to the immobile major elements(Al +/- Fe).

The last million years recorded at the Stari Slankamen (Northern Serbia) loess-palaeosol sequence: revised chronostratigraphy and long-term environmental trends
Slobodan B. Marković,Ulrich Hambach,Thomas Stevens,George Kukla,Friedrich Heller,William D. McCoy,Eric A. Oches,Björn Buggle,Ludwig Zöller +8 more
TL;DR: The Stari Slankamen loess-palaeosol section is located on the northeastern part of the Srem Loess Plateau (Vojvodina region, North Serbia) and is considered to be one of the most important Quaternary sections in the Carpathian basin this article.
Journal ArticleDOI
Provenance control on chemical indices of weathering (Taiwan river sands)
TL;DR: In this article, the concentration of chemical elements in terrigenous sediments is constrained by the original mineralogy of source rocks, and is thus provenance-dependent, and the mineralogy and geochemistry of sediments may undergo substantial modifications by diverse physical processes during transport and deposition, including recycling and hydraulic sorting by size, density or shape, and/or by chemical dissolution and precipitation during diagenesis.

Provenance versus weathering control on the composition of tropical river mud (southern Africa)
Eduardo Garzanti,Marta Padoan,Massimo Setti,Alberto López-Galindo,Igor M. Villa,Igor M. Villa +5 more
TL;DR: In this paper, the authors present an integrated mineralogical-geochemical database on fine-grained sediments transported by all major rivers of southern Africa, including the Zambezi, Okavango, Limpopo, Olifants, Orange and Kunene.
Journal ArticleDOI
Pleistocene environmental dynamics recorded in the loess of the middle and lower Danube basin
TL;DR: The Danubian loess stratigraphy comprises distinct loess-paleosol sequences, reflecting glacial-interglacial phases which can be quantified for intensity using environmental magnetism and geochemistry as mentioned in this paper.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Environmental Chemistry of Soils
TL;DR: In this article, an introduction to modern soil chemistry describes chemical processes in soils in terms of established principles of inorganic, organic, and physical chemistry, providing an understanding of the structure of the solid mineral and organic materials from which soils are formed.

TL;DR: The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick succession of sedimentary and volcanic rocks deposited between about 2,500 and 2,100 Myr ago as discussed by the authors.
