We report on the detection of discrete grains of crystalline graphite and graphite whiskers (gws) in an apollo 17 impact melt breccia. breccias can be formed in many different geologic processes ( tectonic, volcanic. Dhofar 1766 18.592°n, 54.271°e zufar, oman found: (2005) objected to many aspects of our interpretation:
Purchased in 2021 by matthew and travis stream from a meteorite dealer in algeria.
Contains zircons with secondary microstructures generated by impact processes. The stone is complete, oriented, and appears relatively unweathered. Impact melt (quenched coherent material) is lunar meteorite (feldspathic breccia) physical characteristics: The recrystallized matrix indicates that this sample is from a melt sheet of fallback breccia inside a relatively large lunar crater. lunar melt breccia 73217 investigated by grange et al. breccias can be formed in many different geologic processes ( tectonic, volcanic. Full slice of this marvelous melt breccia from vesta. The exact location of find is unknown but it is possibly in algeria. The latter is variable in texture and clast content and might even represent more than a single lithology. Images of lunar melt breccia 65015, apollo 16 landing site. Please select parameters and make your search. Multiple instances of graphite and gws within a discrete area of the sample imply that these grains are not terrestrial contamination.

(2007) on the structure of mare basalt lava flows from textural analysis of the lapaz icefield and northwest africa 032 lunar meteorites. Identifying an (exogenous) impact origin for some lunar components as opposed to a endogenous crustal (igneous) derivation. This is 1 of 5 approved meteorites classified as lunar (melt breccia) northwest africa 13788 (nwa 13788) ouargla, algeria.

We described lunar meteorite dhofar 026 (cohen et al. Contributions to mineralogy and petrology , 169 (3). Clasts are all related to the ferroan anorthosite suite, and include isolated plagioclase crystals and lithic anorthosites, troctolites, and spinel troctolites. Glassy breccias form from impact melt that. They were uncertain whether or not the bulk rock had been shocked; lunar melt breccia 73217 investigated by grange et al. 88 mm x 62 mm x 3 mm. lunar meteorite (melt breccia) history: Images of lunar impact breccia 14305, "fra mauro formation", apollo 14 landing site. The lead author is sheng gou, from the laboratory of remote sensing science, aerospace.

That may be similar to or different from the fragmented material. (2005) objected to many aspects of our interpretation: Pdf | on aug 31, 2001, p.
The latter is variable in texture and clast content and might even represent more than a single lithology.
Many of the larger clasts are themselves breccias containing olivine clasts within … The mare basalts, norites, and mafic impact melt breccias have respective multiplicative uncertainties of 1.6, 1.6, and 2.2, whereas the small number of anorthosite samples precludes calculating an uncertainty. lunar meteorite que 93069 found in antarctica is a mature, anorthitic regolith breccia with highland affinities that was ejected from the moon <0.3 ma ago. 88 mm x 62 mm x 3 mm. lunar highland meteorite dhofar 026 and dhofar 301, 302, and 303: lunar meteorite (melt breccia) history: lunar meteorite (impact melt breccia) a 1015 g stone was purchased on 2001 january 10 in alnif, morocco, by michael farmer. Website developed by sergey vasilevsergey vasilev The rock is cut by glassy and vesicular melt veins and melt pockets, which suggest an uncommonly intense shock, possibly linked with the violent launch off the moon. Contains zircons with secondary microstructures generated by impact processes. Abstract we have analyzed nine highland lunar meteorites (lunaites) using mainly inaa. The exact location of find is unknown but it is possibly in algeria. With its high spatial resolution, the uvlamp 40 ar/ 39 ar method offers an important complementary way to date impact melts that is especially useful for.

Abstract we have analyzed nine highland lunar meteorites (lunaites) using mainly inaa. Clasts are all related to the ferroan anorthosite suite, and include isolated plagioclase crystals and lithic anorthosites, troctolites, and spinel troctolites. Contains zircons with secondary microstructures generated by impact processes.
They were uncertain whether or not the bulk rock had been shocked; lunar breccia. The recrystallized matrix and the clast population are both highly anorthositic.
