We report on the synthesis and physical properties of cm-sized CoGeO3 single crystals grown in a high pressure mirror furnace at pressures 80 bar. Direction dependent magnetic susceptibility measurements our reveal highly anisotropic that we attribute to impact strong ion anisotropy appearing this system with TN∼33.5 K. Furthermore, observe effective moments are exceeding spin only values Co io...

Eucrite meteorites are early-formed (>4.5 Ga) basaltic rocks that likely to derive from the asteroid 4 Vesta, or a similarly differentiated planetesimal. To understand trace element and moderately volatile (MVE) behavior more fully within between eucrites, laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) study is reported for plagioclase pyroxene, as well fusion crust vit...

Introduction: The martian basaltic meteorites display enormous variation in their trace element and isotopic compositions. A subset of the shergottites including NWA1195, SaU005/008, DaG476, Y980459, Dhofar 019, and QUE94201 have many similar geochemical features, in addition to being the oldest shergottites. Strongly light-rare-earth element (LREE)-depleted REE patterns, low initial Sr and hig...

Lunar meteorite EET 96008 is a fragmental breccia that predominantly consists of basaltic mineral clasts (0.5–2 mm), along with minor lithic fragments and breccia clasts. The matrix consists mainly of smaller mineral fragments ( 0.5 mm), bound by glassy cement, the majority of which are pyroxene and plagioclase. The pyroxene possesses extensive exsolution lamellae. These lamellae, up to 1 m in ...

The aim of the present contribution was to evaluate trace element mobility in olivine, low-Ca pyroxene and plagioclase Kargapole meteorite under thermal or impact metamorphic conditions recognition properties chondrule-forming events. compositions minerals were analyzed using an electron probe microanalyser (EPMA) a secondary ion mass spectrometer (SIMS). No considerable deviations concentratio...

The prograde metamorphism of eclogites is typically obscured by chemical equilibration at peak conditions and by partial requilibration during retrograde metamorphism. Eclogites from the Eastern Blue Ridge of North Carolina retain evidence of their prograde path in the form of inclusions preserved in garnet. These eclogites, from the vicinity of Bakersville, North Carolina, USA are primarily co...
