متن کاملExperimental Petrology of Olivine-phyric Shergottite Nwa 1068: Toward
Introduction: The olivine-phyric basaltic shergottites (OPSs) have recently been recognized as a significant sub-group of the Martian meteorites. These rocks have many characteristics suggestive of a primitive nature such as high bulk and olivine-core Mg#s [1]. [2,3] conducted crystallization experiments using the composition of Yamato 980459 (Y98), an OPS. Results of these experiments show tha...

Introduction: Knowledge of martian igneous and mantle composition is crucial for understanding mantle evolution including early differentiation, mantle convection and the chemical alteration of the surface. Primitive magmas provide critical information on their mantle source regions but most Martian meteorites crystallized from fractionated melts [1]. The new martian meteorite NWA 5789, discove...
متن کاملVARIATIONS IN LIGHT LITHOPHILE ELEMENTS (Li, B, Be) AND LITHIUM ISOTOPES IN MARTIAN PYROXENES AND OLIVINES: ROLES OF DEGASSING AND DIFFUSION
Introduction: The zoning patterns of light lithophile elements (LLEs: Li, Be, B) in pyroxenes of some Martian meteorites have been used to suggest that the parent basalts were water-saturated, which exsolved and lost an aqueous phase through degassing and eruption, causing depletion in LLEs in the pyroxene rims [1]. In contrast, other investigators have suggested a diffusion controlled fraction...
