Estimation of physicochemical properties and tectonic environment of gabbro masses from south of Germi city (Ardabil province) based on the chemistry of clinopyroxene crystals [PDF]
پترولوژی, 2018 The studied gabbroic rocks, trending northwest- southeast, outcropped in the south of Germi, northwest of Iran. These rocks composed of plagioclase, clinopyroxene and iddingsitic olivines.

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]
, 2017 Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

Zoned Pyroxenes as Prospectivity Indicators for Magmatic Ni-Cu Sulfide Mineralization
Frontiers in Earth Science, 2020 Small intrusions dominated by olivine- and pyroxene-rich cumulates are well known to be favorable hosts to magmatic Ni-Cu-(Platinum Group Element—PGE) sulfide mineralization.

Effects of CO2 flushing on crystal textures and compositions: experimental evidence from recent K trachybasalts erupted at Mt. Etna [PDF]
, 2017 Changes in magmatic assemblages and crystal stability as a response of CO2 flushing in basaltic systems have been never directly addressed experimentally, making the role of CO2 in magma dynamics still controversial and object of scientific debate.
