Physical and chemical properties of the epidote minerals: An introduction
Epidote minerals are known since the 18th century, but at that time the greenish to dark colored varieties were termed actinolite or schorl and not distinguished from the minerals to which theseExpand

Aluminous titanite (sphene) from the Eclogite Zone, south-central Tauern Window, Austria
Abstract Highly aluminous titanite with Al 2 O 3 contents up to 14 wt.% (50% of the CaAlSiO 4 (F,OH) end-member) occurs in siliceous dolomites from the Eclogite Zone, south-central Tauern Window,Expand

Proterozoic–Paleozoic development of the basement of the Central Andes (18–26°S) — a mobile belt of the South American craton
Abstract The Late Precambrian–Early Paleozoic metamorphic basement forms a volumetrically important part of the Andean crust. We investigated its evolution in order to subdivide the area between 18Expand

Composition and density model of the continental crust at an active continental margin—the Central Andes between 21° and 27°S
This paper derives an estimate of the average chemical composition of the Paleozoic Andean basement, based on the geological evolution and from compilations of geochemical and isotopic analyses ofExpand

Slab‐derived boron isotope signatures in arc volcanic rocks from the Central Andes and evidence for boron isotope fractionation during progressive slab dehydration
[1] Late Miocene to Quaternary volcanic rocks from the frontal arc to the back-arc region of the Central Volcanic Zone in the Andes show a wide range of δ11B values (+4 to −7 ‰) and boronExpand

Trace Element Geochemistry of Epidote Minerals
One of the most striking features of epidote minerals is their ability to incorporate significant amounts of geochemically important trace elements such as large ion lithophile elements (LILE),Expand

Distinguishing crustal recycling and juvenile additions at active continental margins: the Paleozoic to recent compositional evolution of the Chilean Pacific margin (36–41°S) ☆
Abstract This paper presents new insights on the evolution of continental crust in a segment of the southern Central Andes (Chile–Argentina; ca. 36–41 °S) from compositional and isotopic age data ofExpand

Ordovician metamorphism and plutonism in the Sierra de Quilmes metamorphic complex: Implications for the tectonic setting of the northern Sierras Pampeanas (NW Argentina)
Towards unravelling the geodynamic setting of the northern Sierras Pampeanas (NW Argentina) we describe the tectono-metamorphic and geochronologic evolution of sub-greenschist to granulite faciesExpand

Nd, Pb, and Sr isotope composition of juvenile magmatism in the Mesozoic large magmatic province of northern Chile (18–27°S): indications for a uniform subarc mantle
The Jurassic to Early Cretaceous magmatic arc of the Andes in northern Chile was a site of major additions of juvenile magmas from the subarc mantle to the continental crust. The combined effect ofExpand

Isotopic composition of Late Mesozoic basic and ultrabasic rocks from the Andes (23–32°S) – implications for the Andean mantle
Abstract.Mesozoic mantle-derived magmatic rocks from the Jurassic–Early Cretaceous active continental margin of N Chile near 24°S, and from the Cretaceous rift system of NW Argentina near 26°SExpand
