TLDR
In this paper, the authors analyzed granitic plutons from New Mexico for major and trace elements and classified them into four groups: high-Ca, high-Si and high-K, and trondhjemite.About:

Journal ArticleDOI
Trace element discrimination diagrams for the tectonic interpretation of granitic rocks
TL;DR: In this article, a data bank containing over 600 high quality trace element analyses of granites from known settings was used to demonstrate using ORG-normalized geochemical patterns and element-SiO2 plots that most of these granite groups exhibit distinctive trace element characteristics.

A model for Trondhjemite-Tonalite-Dacite Genesis and crustal growth via slab melting: Archean to modern comparisons
Mark S. Drummond,Marc J. Defant +1 more
TL;DR: In this paper, the authors introduced the importance of subducted oceanic crustal age on arc petrogenesis and demonstrated that Archean TTD crustal generation processes are also present in selected high-Al Phanerozoic TTD terranes.

Monazite solubility and dissolution kinetics: implications for the thorium and light rare earth chemistry of felsic magmas
Robert P. Rapp,E. Bruce Watson +1 more
TL;DR: A series of monazite dissolution experiments was conducted in a hydrous (1-6 wt%) granitic melt at 8 kbar over the temperature range 1,000-1,400° C.
Journal ArticleDOI
Nature and origin of Proterozoic A-type granitic magmatism in the southwestern United States of America
TL;DR: For example, the Holy Moses and Hualapai plutons in western Arizona have been shown to exhibit a significant change in the oxygen fugacity as discussed by the authors, reaching a high of 0.27, down from more typical levels of 0,54 to 0.75.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more
TL;DR: A table of abundances of the elements in the various major units of the Earth's lithic crust with a documentation of the sources and a discussion of the choice of units and data is presented in this article.

Trace element fractionation during anatexis
TL;DR: The theoretical basis of trace element fractionation presented in a paper by P. W. Gast (1968) can be developed in a more flexible algebraic form, which is described and illustrated in this article.

Relative and Absolute Terrestrial Abundances of the Rare Earths
TL;DR: In this article, the relative rare-earth abundances in composite samples of shales, metamorphosed shales and chondritic meteorites are reported, showing that common crustal rocks are deficient in Eu, relative to the other rare earths.

A Linear Programming and Least Squares Computer Method for Solving Petrologic Mixing Problems
TL;DR: In this paper, a two-stage computer-based approach was used to solve the problem of petrologic mixing using linear programming and a conventional least square calculation, with the analyses represented by non-negative solution values as input to yield an optimum set of solution values.

Instrumental activation analysis of standard rocks with high-resolution γ-ray detectors☆
TL;DR: In this paper, the element abundances in igneous rocks measured by instrumental neutron activation using high resolution lithium drifted germanium detectors were investigated. But the results were limited to a single element.
