NWA 7676 was recovered out of the Moroccan Sahara in early 2012. It was analyzed at UWS by Dr. Tony Irving and classified as a LL3 chondrite that is relatively fresh at W1 and lightly shocked at S2. It is notably metal poor and loaded with chondrules.
The specimen listed here is a thick slice (slab) that weighs 3.1 grams. One side has prominent 5mm chondrule. There is also a small "dark inclusion" on one side.
Refer to the photos. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. Your purchase will include a labeled gemjar.
