Hello and thank you for viewing my listing. Today you are purchasing a cutting fragment specimen of NWA 10441 Achondrite Martian Shergottite Meteorite from Northwest Africa. Beautiful specimen with killer details and characteristics. Getting quite low in inventory. The specimen you see is NOT the specimen you are buying. I use a stock photo for micros. Repeat, this is NOT the exact specimen you are purchasing. Gem case is NOT included, just for reference photos. Specimen micros in a gem case, are in my store buy it now. Below is the data for my classification. Excellent rare addition to your collection.

My catalog number is G613-0118 and the specimen weighs in at micro grams and comes in a gem case with my card of authenticity for provenance. Remember, provenance is a must when collecting meteorites. I have designed a COA for NWA 10441, as I do with all of my classifications. The specimen you see pictured is NOT the exact specimen you will receive. Each card comes with my catalog number, weight and signature of authenticity and logged into the book of provenance. Thanks again for viewing. Cheers!

Thanks again for viewing and my shipping is like this, the first is usually only $5.95 and .50 cents for each additional item, unless over 60 grams, then 1.00 per item. Cheers and thanks again for stopping by.

(Northwest Africa)

Purchased: April 2015

Classification: Martian meteorite (Shergottite)

History: Purchased by team eegooblago (Brahim Tahiri, Dustin Dickens and Sean Tutorow) while on expedition in Northwest Africa and Western Sahara in April and May 2015.

Physical characteristics: Six indentical appearing stones with no fusion crust. Saw-cut surfaces show an intergranular mix of light-green pyroxene and maskelynite. Dark colored melt veins and pockets are prominent, with most showing significant vesiculation.

Petrography: (C. Agee, UNM) This meteorite consists of ~50% pyroxene, ~30% maskelynite, and ~15% shock melt. Pyroxenes show igneous zoning, and some are partially melted from shock. Shock melt domains are up to 1 cm wide and many contain vesicles 1-3 mm in diameter. All plagioclase has been transformed to maskelynite. Fe-sulfide, Ti-magnetite, ilmenite, and silica observed.

Geochemistry: (C. Agee and N. Muttik, UNM) Pigeonite Fs49.5±9.2Wo15.7±3.3, Fe/Mn=36±3, n=31; augite Fs28.4±6.7Wo33.3±2.0, Fe/Mn=32±3, n=33; maskelynite An53.8±1.7Ab44.2±2.0Or2.1±0.7.
