Rare-earth element (REE) analyses of 68 rocks and mineral separate samples from the Samail ophiolite clearly differentiate the various units of the ophiolite suite and indicate that the crustal suite is cogeneitc, produced by crystal fractionation of basaltic magma in a spreading ridge magma chamber...
(Tb-Lu and Y). In this review, we classify them into light rare earth elements (LREEs: La-Eu) and heavy rare earth elements (HREEs: Gd-Lu and Y), because Gd is selectively incorporated into HREE minerals like xenotime. We also note that “light” and “heavy” are most commonly ...
Rare earth element geochemistry of the Scourian complex N.W. Scotland — Evidence for the granite-granulite link These new data, along with previously reported major and trace element data, isotopic abundances, and trace element modelling support the hypothesis that t... C Pride,GK Muecke - 《...
Backup and fastening device for preventing slipping of e.g. earth material, has support element that are connected to each other in parallel to longitudinal axis to form stack, and mounting element that is provided with support elementThe device (1) has a support element (2) that is provided...
veneer (Pt/Pd ∼1.8;Palme and Jones, 2005), or containing a component of the Earth’s core. Many Ni-Cu deposits, particularly those hosted by komatiites, crystallize from primitive magmas that have flat mantle-normalized trace-element patterns. These magmas are unlikely to be derived from ...

Geochemical analysis reveals that the apatite in the central zone has been re-crystallised from the BX1 type apatite breccia with the REE partitioned into allanite and REE-poor apatite. The evidence to support this includes no europium anomaly within the BX1 type apatite and a large negative ...

(2014) who concluded that increasing in magmatic water content from the Paleocene–Eocene to the Oligo-Miocene was essential to the formation of post-subduction large- to giant-sized porphyry Cu–Mo ± Au deposits. This paper is devoted to whole-rock rare earth element geochemistry of intrusive...
