H. Wayne Nesbitt,G. Markovics +1 more
TLDR
The Toorongo Granodiorite, Australia, is similar to the average upper continental crust (AUCC) and the weathering characteristics of the profile provide insight into large-scale chemical weathering of the upper crust as mentioned in this paper.About:

Journal ArticleDOI
Relationships between the trace element composition of sedimentary rocks and upper continental crust
TL;DR: In this paper, the upper crustal abundances of several trace elements, including rare earth elements (REEs), were compared to the upper continental crust of the United States, and the results showed that no revisions are needed for these elements.
Journal ArticleDOI
The effect of time on the weathering of silicate minerals: why do weathering rates differ in the laboratory and field?
Art F. White,Susan L. Brantley +1 more
TL;DR: In this article, the correlation between decreasing reaction rates of silicate minerals and increasing duration of chemical weathering was investigated for both experimental and field conditions, and it was shown that intrinsic surface area, which increases with the duration of weathering, was responsible for a third of the exponential decrease in the weathering rate.

Quantitative paleoenvironmental and paleoclimatic reconstruction using paleosols
Nathan D. Sheldon,Neil J. Tabor +1 more
TL;DR: Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings ranging from alluvial systems to between basalt flows as mentioned in this paper, and a variety of semi-quantitative and quantitative tools have been developed to examine past weathering and pedogenesis, and to reconstruct both paleoenvironmental and paleoclimatic conditions at the time that the paleosols formed.
Journal ArticleDOI
The geochemistry of shales, siltstones and sandstones of Pennsylvanian-Permian age, Colorado, USA : implications for provenance and metamorphic studies
TL;DR: In this paper, a series of shales and sandstones found near the source of the Sangre de Cristo, Belden, and Maroon Formations from central Colorado were examined petrographically and were analyzed for major and selected trace elements, including the REE.
Journal ArticleDOI
Rare earth elements in soil and plant systems - A review
TL;DR: A review of recent and current literature deals with rare earth elements in primary and secondary soil minerals, concentrations in surface soils, factors influencing adsorption, solubility and transport in soils, including weathering and transformations of rare earth minerals, and vertical distribution in soil profiles 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.

Early Proterozoic climates and plate motions inferred from major element chemistry of lutites
H.W. Nesbitt,Grant M. Young +1 more
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.
Journal ArticleDOI
Prediction of some weathering trends of plutonic and volcanic rocks based on thermodynamic and kinetic considerations
H.W. Nesbitt,Grant M. Young +1 more
TL;DR: In this paper, the proportions of Ca, Na and K released by feldspars of plutonic rocks (granites to gabbros) to weathering solutions were predicted.

An accurate X-ray spectrographic method for the analysis of a wide range of geological samples
K Norrish,J.T Hutton +1 more
TL;DR: In this article, a fusion with lithium borate containing lanthanum oxide is used to make a suitable glass disc for accurate X-ray spectrographic analysis of geological samples of widely varying composition.
