This is a preliminary name for ID purposes only. A piece of 570 grams (470 after cutting) was found in a shipment of Gao-Guenie from Burkina Faso and hence the temporary name. It has been classified as an H5 Impact melt breccia with an Fa of 17.9 by Arizona State University. These numbers are similar to Gao itself so despite the very different appearance there are questions of whether it is a new meteorite or not. Additional tests on the CRE age are being conducted to confirm or deny the relationship with Gao. There are no known examples of impact melts like Gao (b) associated with relatively unshocked material like Gao in the same fall. Such an association could provide interesting information on asteroid impact dynamics. On the other hand it could be an entirely different meteorite which is similar to Cat Mountain or Rose City. The U of Arizona also has a sample and will be doing in depth analysis of this meteorite.
There were a number of vugs in this meteorite. The largest was shaped like a hershey's kiss and was 1 cm across the base and 1 cm tall. The hole crossed 3 slices which now are part of the ASU collection. Some other interesting features are the metal features which form small spheres in some of the melt and as stream lines in some of the melt flow. A few of the slices also have cracks that only extend from one side of the melt flow to the other side of the flow. They are likely tension cracks formed when the melt cooled and contracted. For an example look at the 2.70 gram piece photo # 2.
