Writeup from MB 105:

Northwest Africa 11038 (NWA 11038)

(Northwest Africa)

Purchased: Feb 2016

Classification: Ordinary chondrite (L3)

History: A single stone weighing 2202 g was purchased in February 2016 from a Moroccan dealer

Petrography: (A. Bischoff, S. Ebert, IfP). The rock is unbrecciated. In the studied thin section, abundant well-defined chondrules are visible, sometimes containing mesostasis glass. This indicates a very low degree of secondary alteration. It is an unequilibrated type 3 ordinary chondrite. The chondrules have a size of about 500 μm. The ° of shock and weathering are S2 and W2, respectively.

Geochemistry: Mineral compositions and geochemistry: (K. Klemm and A. Bischoff, IfP) Olivine within the rock is unequilibrated and is Fa25.2±3.8 (range Fa12-30, n=30). The same holds for low-Ca pyroxene, which is also unequilibrated and is Fs13.7±10.5Wo1.5±2.2 (Fs2-37Wo0.2-10.4, n=30).

Specimens: 30.9 g including a polished thin section are at the IfP. Sergey Vasiliev holds the main mass.
