Rare-earth abundances in chondritic meteorites
TLDR
In this article, 15 chondrites, including eight carbonaceous chondites, were analyzed for rare earth element abundances by isotope dilution, and the persistence of anomalies in chondritic materials relatively removed from direct condensational processes implies that anomalous components were introduced at a late stage of chondrite formation.About:

Geochemistry and petrogenesis of Neoarchaean high-Mg low-Ti mafic igneous rocks in an intracratonic setting, Central India craton: Evidence for boninite magmatism
TL;DR: In this paper, the authors classified high-Mg mafic igneous rocks into high-Ca and low-Ca (Type 3) boninites using trace element modelling.

Petrology, geochemistry and paleomagnetism of the earliest magmatic rocks of Deccan Volcanic Province, Kutch, Northwest India
TL;DR: In this paper, Petrological, geochemical and paleomagnetic data for representative samples of the volcanic and intrusive rocks from Kutch region are presented, which are classified into three groups on the basis of spatial distribution, mode of occurrence and petrochemistry.

Geochemical characteristics of the Eymir (Sorgun-Yozgat) manganese deposit, Turkey
TL;DR: The Eymir manganese deposit in Yozgat-sorgun, Turkey was studied by means of major oxide, trace and rare earth element (REE) contents and the origin of mineralization was discussed.

Uranium, rare metals, and granulite-facies metamorphism
TL;DR: The Lapland metasedimentary granulites illustrate the behaviour of the LILE and rare metals during lower crustal metamorphism as discussed by the authors, showing distinct behaviours with respect to these elements.

Early post-collisional granitic and coeval mafic magmatism of medium- to high-K tholeiitic affinity within the Neoproterozoic Southern Brazilian Shear Belt
TL;DR: The Paulo Lopes Suite (PLS) is composed of metaluminous to slightly peraluminous biotite-hornblende Paulina Lopes and Garopaba granitoids as mentioned in this paper.

Synthesis of the Elements in Stars
TL;DR: In this article, a count of the stable and radioactive elements and isotopes is given, and Table I,1 shows that only promethium has not been found in nature, whereas 99 elements are found terrestrially and technetium is found in stars.

Determination of REE, Ba, Fe, Mg, Na and K in carbonaceous and ordinary chondrites
TL;DR: In this paper, the exact determination of REE and Ba abundances in three carbonaceous (Orgueil Cl, Murchison C2 and Allende C3) and seven olivine-bronzite chondrites were carried out by mass spectrometric isotope dilution technique.

A chemical-petrologic classification for the chondritic meteorites.
W. R. Van Schmus,John A. Wood +1 more
TL;DR: In this article, a two-dimensional classification grid based on chemical and petrologic subdivisions of chondritic meteorites is proposed, which extends the current chemical subdivisions to account for varying petrolic (implied metamorphic) properties within the primary chemical groups.
