Recent studies showed that Cl-rich hydrothermal liquids are enriched in LREE, and the Hf/Sm, Nb/La, and Th/La ratios are less than 1 while the F-rich hydrothermal liquids are simultaneously enriched in LREE and HFSE
with the Hf/Sm, Nb/La, and Th/La ratios generally larger than 1 (Oreskes and Einaudi, 1990; Bi et al., 2004; Mao et al., 2006).

In 2015, the RNHR was made up of 233 hospital-based Epidemiological Surveillance units distributed across the country, including the HFSE
Con respecto a los diagramas multielementales nos muestran un ligero enriquecimientos de los elementos LILE de Ba, Th, Ta y un empobrecimientos de los otros elementos LILE y HFSE
. Se aprecian anomalias negativas de Nb y Ti en San Lorenzo y de Ti en La Bocana y anomalias positivas de Ce y Th en ambas formaciones que indican una relacion al marco tectonico de subduccion de placas.
and REE also decrease their concentration in amphiboles with lower Ti (Fig.

The same is true for the Nb-anomaly as well as for ratios of large-ion lithophile elements (LILE) to light rare earth elements (LREE) and LILE to high-field strength elements (HFSE
) (see  for the importance of these ratios for subduction processes).
The discussion on Internet Communication and the Ethical Implications of the Human Flesh Search Engine (HFSE
) probably started in China in 2008 when a deadly earthquake struck Sichuan province and left many people missing.
Although clay adsorption of these elements will play a role, much of the HFSE
content of natural continental desert [PM.sub.10] is contained within tiny nuggets of phosphates and Ti-oxides, and these have the potential to be extremely long-lived and recyclable (e.g.
Thus geochemical/ petrological investigations of komatiites have been based upon elements that are considered to be less mobile, including Al, Ti, high-field-strength elements (HFSE
) and rare-earth elements (REE).
