Investigation of the formation processes in the mafic enclaves of Naqadeh plutonic rocks assemblage by zircon U-Pb dating, Sr-Nd isotopic ratios, and amphibole composition [PDF]
Naqadeh intrusive pluton is composed of two distinct sections of felsic (40 Ma age) and mafic (99 Ma age) rocks. The granitoid rocks of Naqadeh pluton have different types of mafic enclaves, including mafic microgranular enclaves (MME) and quartz ...

Approach to amphibole in Zaydari Nasaviâs Nafthat-o-Almasdour [PDF]
“Nafthat-o-Almasdour” book is one of the excellent examples of technical and stilted prose in the seventh century. The author of this work with complete mastery and benefit from a variety of literal and spiritual figures of speech has revealed his art in

Geothermobarometry of Sarmeshk granitoids in the Northwest of Sarduiyeh [PDF]
The Sarmeshk granitoid pluton is located in southeast of the Urumieh-Dokhtar magmatic zone in the Kerman province. Based on petrographic studies, the granitoid consist of three rock type of diorite, granodiorite and monzogranite. They are mainly composed

Polarons in Rock-Forming Minerals: Physical Implications
The existence of thermally-activated quasiparticles in amphiboles is an important issue, as amphiboles are among the main hydrous complex silicate minerals in the Earth’s lithosphere.

Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy
Seismic anisotropy is controlled by aligned rock‐forming minerals, which most studies attribute to solid‐state shear with less consideration for magmatic fabric in plutonic rocks (rigid‐body rotation of crystals in the presence of melt).

Research subject. The article discusses the features of the relationship between biotite and amphibole on the example of magmatogene melanocratic rocks from a number of granitoid massifs of the Urals. These rocks form xenoliths and synplutonic intrusions

Magnetic petrology of the Água Azul and Água Limpa granodiorites, southern portion of the Carajás Domain – Pará [PDF]
The Água Azul and Água Limpa granodiorites (AAGrd and ALGrd, respectively) outcrop in the extreme southern of the Carajás Domain as two elongated bodies following the EW regional trend and were previously included in the Xingu Complex. The ALGrd consists

APG: An Efficient Software Program for Amp-Pl Thermobarometry Based on Graphical Method [PDF]
Geothermobarometry equations are based on thermodynamic principles and appear in single or multi-variant functions. The number of variants for a specific composition or reaction usually is reduced into 2 involving temperature (T) and pressure (P).
