Writeup from MB 101:

Dhofar 1668 (Dho 1668)        18.322°N, 54.148°E

Zufar, Oman

Found: 2010 Nov

Classification: Martian meteorite (Shergottite)

History: Purchased by Patrick Cavanaugh from an anonymous finder.

Physical characteristics: A single small, brown stone (6.1 g) lacking fusion crust.

Petrography: (A. Irving and S. Kuehner, UWS) Small zoned olivine phenocrysts (with some secondary iron hydroxide staining) occur with prismatic grains of zoned pigeonite and maskelynite, together with accessory Fe-Ti oxides (intergrown ilmenite+magnetite), chromite, pyrrhotite, merrilite and chlorapatite. Minor secondary gypsum and calcite present.

Geochemistry: Olivine (Fa41.4-64.1, FeO/MnO = 56-59), pigeonite (Fs29.1-40.0Wo9.6-11.5, FeO/MnO = 31-34), plagioclase (An57.2-62.8Or0.7-0.2).

Classification: Martian (shergottite, olivine-phyric). The find location, texture and mineralogy imply that this stone is paired with Dhofar 019.

Specimens: 1.25 g and one polished thin section are on deposit at UWB. Mr. P. Cavanaugh, Boise, Idaho, holds the main mass.
