Constraints on the uptake of REE by scheelite in the Baoshan tungsten skarn deposit, South China
TLDR
In this article, the scheelite was classified into three types: prograde, retrograde, and semi-retrograde skarns, and the lattice strain model was used to estimate the relative distribution of rare earth element (REE) in scheelites and to predict the relative distributions of REE in the ore-forming fluids.About:

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.

In situ analysis of major and trace elements of anhydrous minerals by LA-ICP-MS without applying an internal standard
TL;DR: In this paper, an internal standard-independent calibration strategy for LA-ICP-MS analysis of anhydrous minerals and glasses was described, where the ablation yield correction factor (AYCF) was used to correct the matrix-dependent absolute amount of materials ablated during each run.

Petrogenesis of Mesozoic granitoids and volcanic rocks in south China : a response to tectonic evolution.
TL;DR: In this paper, the authors proposed that these rocks were formed in time and space as a response to regional tectonic regime change from the continent-continent collision of the Indosinian orogeny within the broad Tethyan orogenic domain in the Early Mesozoic (T1-T3) (Period I) to the largely extensional setting as a result of the Yanshanian Orogeny genetically associated with the NW-WNW-ward subduction of the paleo-Pacific oceanic lithosphere in the Late Mesozooric (J
