Electrostatic energy for ion clustering in intermediate plagioclase feldspar
Electrostatic calculations estimated the energy of hypothetical ion clustering in intermediate plagioclase feldspars. The calculated energy appears too great to allow segregation of Ca and Na atoms into domains upon annealing without a corresponding movement of A1 and Si from an original disordered structure. The calculated energy may be sufficiently small that Ca and Na atoms can disorder part...
متن کاملDecoupling of Ree in Plagioclase and Orthopyroxene in the Lunar Ferroan Anorthosite
Introduction: According to the canonical lunar magma ocean (LMO) model, ferroan anorthosites (FANs) were part of the lunar anorthosite crust formed via plagioclase flotation and subsequent solidification in a globally distributed LMO [1-4]. The solidification time for a globally distributed LMO is model dependent and ranges from 10 4-10 8 yrs [3,5,6]. At a given time during lunar crust formatio...
متن کاملImplications for the origins of pure anorthosites found in the feldspathic lunar meteorites, Dhofar 489 group
Remote observation by the reflectance spectrometers onboard the Japanese lunar explorer Kaguya (SELENE) showed the purest anorthosite (PAN) spots (>98% plagioclase) at some large craters. Mineralogical and petrologic investigations on the feldspathic lunar meteorites, Dhofar 489 and Dhofar 911, revealed the presence of several pure anorthosite clasts. A comparison with Apollo nearside samples o...

15 صفحه اولAnorthosite first occurrence in Nigeria and relevance to Younger Granite genesis
Plagioclase crystal fragments and a block of anorthosite occur in small basaltic dykes on the Jos Plateau. The anorthosite is unusual, for the feldspar is labradoritic, but the interstitial mineralogy is granitic rather than basic, displaying granophyric intergrowths in places. The anorthosite is probably not an intermediate stage in fractionation from a basic parent magma towards granite, sinc...
