Discussão sobre a determinação da idade do granito do Porto pelo sistema Rb-Sr: implicações do valor da constante de decaimento do 87Rb [PDF]

, 2015
A determinação da idade absoluta por métodos isotópicos constitui um dado indispensável no constrangimento das condições petrogenéticas e evolutivas de uma rocha, contribuindo para uma melhor caraterização do seu enquadramento geológico e tectónico.

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Early history of the moon: Implications of U-Th-Pb and Rb-Sr systematics [PDF]

Anorthosite 60015 contains the lowest initial Sr-87/Sr-86 ratio (0.69884 + or - 0.00004) yet reported for a lunar sample. The initial ratio is equal to that of the achondrite Angra dos Reis and slightly higher than the lowest measured Sr-87/Sr-86 ratio ...

Rb-Sr and Sm-Nd mineral isochron ages of a pegmatitic gneiss from Oku-iwa Rock, Lutzow-Holm Complex, East Antarctica [PDF]

, 2006
Oku-iwa Rock is located in the transitional zone between granulite- and amphibolite-facies metamorphic zones in the Lutzow-Holm Complex (LHC), East Antarctica. Hornblende biotite (HB) gneiss widely outcrops in the northern part of this area. Sm-Nd and Rb-

The SWITCH algorithm: An expert consensus on treat‐to‐target criteria for chronic prurigo

Journal of the European Academy of Dermatology and Venereology, EarlyView.
The SWITCH project assessed patients' most distressing symptoms and therapy goals, followed by an expert‐based consensus procedure to define T2T criteria for patients with chronic prurigo (CPG)/prurigo nodularis. Based on these validated criteria, a 4‐step SWITCH algorithm was established to enhance CPG therapy outcomes and reduce patient burden ...

Climatic changes recorded during the Jenkyns Event (Early Jurassic) in the lacustrine sediments of the Sichuan Basin (China)

Geogaceta
The Toarcian lacustrine deposits of the Sichuan Basin (China) are represented mainly by silty marlstones and bivalve rich limestones disposed in decametric-scale thickening upwards sequences. Dense accumulations of bivalve shells are related to episodes

Rb-Sr and Sm-Nd dating of olivine-phyric shergottite Yamato 980459: Petrogenesis of depleted shergottites [PDF]

, 2005
Martian meteorite Yamato (Y) 980459 has undergone terrestrial weathering in Antarctica. The weathering has affected the Sm-Nd isotopic system. Acid-washed pyroxenes, whole rock and quenched glass samples define a Sm-Nd isochron age of 472±47 (±2σ) Ma and

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.
