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...

15 صفحه اولFractals in petrology
A fractal (power-law) distribution is the only statistical distribution applicable to a scale-invariant process. One of the major problems in petrology is the distribution of trace elements in the Earth’s crust. Extreme values of this distribution result in ore deposits. There is accumulating observational evidence that tonnage–grade statistics of ore deposits are often fractal (powerlaw). Rayl...
