Partial melting and melt migration in the acapulcoite-lodranite parent body
We review petrologic evidence that the acapulcoites and lodranites formed by < 1 ~01% to probably >20 ~01% whole rock partial melting of a chondritic precursor material. At low degrees of partial melting, only Fe,Ni-FeS cotectic melting occurred. Migration distances for partial melts were short, resulting in the formation of acapulcoites with essentially chondritic troilite and plagioclase cont...
متن کاملThermal Constraints from Siderophile Trace Elements in Acapulcoite- Lodranite Metals
Introduction: A fundamental process in the formation of differentiated bodies is the segregation of metal-sulfide and silicate phases, leading to the formation of a metallic core. The only known direct record of this process is preserved in some primitive achondrites, such as the acapulcoite-lodranites. Meteorites of this clan are the products of thermal metamorphism of a chondritic parent. Mos...
متن کاملCoarse graining from coarse-grained descriptions.
We present a generalization of Zwanzig's method of projection operators to the case where the underlying dynamics is not deterministic. The method allows us to perform a coarse graining of an already coarse-grained level of description in which fluctuations are important. The initial level of description is described by a Fokker-Planck equation and, under suitable approximations, the final slow...
متن کاملAsteroid Surface Mineralogy Using Hapke Mixing Models: the Spectral Effects of Coarse-grained Metal
Introduction: The spectral properties of asteroid surfaces are governed by the mineralogy, the physical state, the amount of impact-produced glass, and the degree of space weathering of the asteroid regolith. Hapke's theories [1,2] and the work of [3] were used to create a model that calculates the spectrum of an airless planetary surface for a given modal mineralogy and mineral chemistry, with...
متن کاملHigh-Resolution Coarse-Grained Modeling Using Oriented Coarse-Grained Sites.
We introduce a method to bring nearly atomistic resolution to coarse-grained models, and we apply the method to proteins. Using a small number of coarse-grained sites (about one per eight atoms) but assigning an independent three-dimensional orientation to each site, we preferentially integrate out stiff degrees of freedom (bond lengths and angles, as well as dihedral angles in rings) that are ...
