Dhofar 1674 (Dho 1674)        18.317°N, 54.202°E

Zufar, Oman

Found: 2010 Nov 21

Classification: Martian meteorite (Shergottite)

History: Found by a prospector near the find site of Dhofar 019 and Dhofar 1668.

Physical characteristics: A single 49.2 g stone lacking fusion crust and with a thin brown weathering patina. The pale-brown interior is mostly fresh with small darker brown olivine grains in a groundmass containing sparkling maskelynite.

Petrography: (A. Irving and S. Kuehner, UWS) Small olivine phenocrysts are set in a groundmass of zoned clinopyroxene (predominantly low-Ca compositions) and intermediate plagioclase (maskelynite), with accessory ilmenite, chromite, pyrrhotite, merrillite and chlorapatite.

Geochemistry: Olivine (Fa48.7-58.9; FeO/MnO = 47-55), pigeonite (Fs25.0-34.5Wo11.6-9.7; FeO/MnO = 30-34), subcalcic augite (Fs18.8-21.2Wo30.5-28.5; FeO/MnO = 23-24).

Classification: Martian (shergottite, olivine-phyric). Paired with Dhofar 019 and Dhofar 1668.

Specimens: A total of 9.98 g of material is on deposit at UWB. The main mass is held by an anonymous collector.
