Geochemical characteristics of apatite in metabasic rocks under different metamorphic conditions: a case study from the Paleoproterozoic Trans-North China Orogen

Dizhi lixue xuebao
Objective  Apatite is a common accessory mineral that is widely distributed in various rock types. Its U-Pb age, trace elements (particularly REE, Th, U, and Sr), and Sr-Nd isotopic compositions provide important information on its chronology and ...

Evolution of feldspars at the amphibolite-granulite-facies transition in augen gneisses (SW Norway): geochemistry and Sr isotopes

, 1990
The Sveconorwegian Augen Orthogneisses of Rogaland - Vest-Agder (SW Norway) were emplaced as amphibole- and biotite-bearing granodiorites at 1040 Ma (concordant Rb/Sr and zircon U/Pb ages).

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria)

Geologica Acta, 2009
Podiform chromitite bodies occur in highly serpentinized peridotites at Dobromirtsi Ultramafic Massif (Rhodope Mountains, southeastern Bulgaria). The ultramafic body is believed to represent a fragment of Palaeozoic ophiolite mantle.

Garnet (Almandine-Spessartine) Growth Zoning and Its Application to Constrain Metamorphic History in Dehsalm Complex, Iran [PDF]

Journal of Sciences, Islamic Republic of Iran, 2006
Dehsalm Metamorphic Complex located in east of Iran consists of regionally metamorphosed rocks intruded by three phases of granitic masses. Synkinematic porphyroblasts of garnet from staurolite-garnet schist present well preserved growth zoning. Electron
