Introduction: Lunar meteorites arguably provide a wider sampling of the lunar surface compared to the samples collected during the Apollo and Luna Missions. Apatite is the main hydroxyl-bearing (proxy for water) mineral in lunar samples, especially in basaltic rocks. The ages of lunar basaltic meteorites also span a larger range compared to basaltic samples collected during Apollo and Luna miss...

Lunar meteorites provide a wider sampling of the lunar surface compared to the samples collected during the Apollo and Luna Missions. Apatite is the main hydroxyl-bearing (proxy for water) mineral in lunar samples, especially in basaltic rocks. Apatite is also amenable to in-situ U-Pb age dating studies. The ages of lunar basaltic meteorites also span over a larger range compared to basaltic sa...

Introduction: One of several models that has been proposed to explain the present chemical and minera-logical nature of the Martian surface is referred to as the " acid-fog " model. This model involves the recent (up to 1Ga), slow and continuous interaction of acidic volatiles, presumably of volcanic origin, with the exposed Martian basaltic crust [1, 2]. As a result of this interaction, minera...

Hornblende occurs in some andesitic and basaltic rocks of calc-alkaline affini1y, where it is commonly associated with olivine. The texture, eruption history, and composition are interpreted to indicate that hornblende commonly forms as a product of reaction between olivine and basaltic and andesitic liquids. The natural hornblendes probably formed within the crust at temperatures between 960o ...

Introduction: One of the major and outstanding problem in Venus geology is: Does Venus possess a non-basaltic crustal component which may be an analog to the continental crust of Earth [e.g. 1]? Detailed photogeologic analysis of plains units that make up the majority of the surface of Venus strongly suggests that the plains were formed by eruptions of low-viscosity lavas [2-4]. Such a morpholo...

We present the observational results of a survey designed to target and detect asteroids whose colors are similar to those of Vesta family members and thus may be considered as candidates for having a basaltic composition. Fifty basaltic candidates were selected with orbital elements that lie outside of the Vesta dynamical family. Optical and near-infrared spectra were used to assign a taxonomi...

[1] The detailed atomic structures of shock compressed basaltic glasses are not well understood. Here, we explore the structures of shock compressed silicate glass with a diopside–anorthite eutectic composition (Di64An36), a common Fe-free model basaltic composition, using oxygen K-edge X-ray Raman scattering and highresolution Al solid-state NMR spectroscopy and report previously unknown detai...
