Dynamic crystallization experiments were initiated on a synthetic composition to study the crystallization behavior of a feldspathic member of the lunar basalt suite and to determine what factors in the cooling history might produce ophitic basaltic textures versus the poikilitic breccia matrix. to a pristine mare basalt () (Fig. 1c). Furthermore, although basaltic sample was originally classified as a pristine high-Al mare basalt (e.g., Longhi et al., ; Ridley et al., ; Crawford and Hollister, ), subsequent experimental studies of dynamic crystallization demonstrated its impact origin (e.g., Usselman and.

basin-scale impacts into a highly feldspathic crust. Basin-sized impacts would likely form a melt with a unique cooling rate and crystallization history relative to smaller-scale impacts. Impact melting of a highly feldspathic target material may also lead to an initial . We have continued our efforts in understanding the crystalliza- tion history of feldspathic basalt , A KmEP basalt, in the hopes that we might arrive at an interpretation of its origin and hence the origin of other lunar samples with the composition.

Gmnite. Compositional term used for lunar rocks or glasses rich in Si and,^. Common composition is approximately Si02 70, A 14, FeO 2, MgO 1, CaO 2, Na20 1, K2 0 7 (weight per cent). The term rhyolite has been used in the same compositional sense. High-alumina basalt. Lunar rocks with % modal (or normative). NWA Lunar Feldspathic Breccia NWA is a jaw-dropping spectacular meteorite! It displays dozens of mm anorthosite and basalt clasts easily seen with the naked eye, and hundreds of mm clasts easily seen with a simple magnifying glass. and the large crystal size indicates an extended cooling period in a thick lava flow.

Lunar feldspathic basalt crystallized at or near the lunar surface from a melt of virtually the same bulk composition as the rock now has. This melt contained no silicate xenoliths or. We report an age of crystallization for spinel-troctolite (VHA basalt) of ± × 10 9 yr (I = ± 6) and an age of crystallization for KREEP-rich basalt of [ ± × 10 9 yr (I = ± 5).

The ages probably date the cooling of shock melts. Zoned lunar pyroxenes have been examined by high voltage (– kV) transmission electron microscopy and electron diffraction, with the particular aim of providing information on the cooling history of individual pyroxenes.

Physical characteristics: The g meteorite has an odd external shape akin to a thick-bladed talon. Petrography: (T. Bunch and J. Wittke, NAU) The sample is a feldspathic fragmental breccia that.

Sample was found as a separate sample without adhering matrix and thus, may or may not have been a clast within the Fra Mauro Formation. It was apparently not photographed on the lunar surface, but it was apparently half buried and the soil line separating the cratered and uncratered surfaces can be easily distinguished.
