Petrology and chemistry of the new shergottite Dar al Gani 476

Crystallization Experiments of Dar Al Gani Martian Meteoites: a Preliminary

Introduction: Recently, a lot of basaltic shergottites have been found from the desert areas in northern Africa and Middle East Asia. Most of them contain large olivine grains that are not present in the previously known basaltic shergottites (except for EETA79001). These olivine grains are mostly Mg-rich, but they show different mineralogical features in each meteorite. Dar al Gani 476 and its...

Experimental 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...

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
