A single fusion-crusted stone weighing 47.1 g was found in the Sahara Desert and was subsequently purchased in Safsaf, Morocco by American collectors. Classification was conducted at Northern Arizona University (T. Bunch and J. Wittke). This very fresh find (W0/1) is classified as an unshocked (S1) CK3. Northwest Africa 1694 is composed of 47 vol% fine-grained matrix, 44 vol% chondrules (up to 1.2 mm), 6 vol% sulfides (containing inclusions of chlorapatite and silica glass), 2 vol% Cr-rich magnetite, and 1 vol% CAIs. Although this CK3 is similar to NWA 772, the two are not considered to be paired.
For petrogenetic details about the CK3 group, see the Dhofar 015 page. The specimen shown above is a 2.2 g partial slice of NWA 1694; the finger that is demonstrating the scale belongs to the accomplished meteorite hunter and photographer, G. Hupé.
