Writeup from MB 106:

Lake Eliza        53°48.5’N, 111°9.5’W

Alberta, Canada

Find: 2003

Classification: Ordinary chondrite (H5)

History: The single, 340 g specimen was found by Mr. Alan Zalaski of St. Paul, Alberta, on one of several meteorite/artifact hunting excursions on family farmland in one of the fields north, east, or south of Lake Eliza, Alberta, in the summer of 2003.

Physical characteristics: The single, rectangular specimen has a reddish brown exterior, partial (~50%) fusion crust, and is cross-cut by numerous fractures.

Petrography: Minor brecciation is present. Shock effects include veining. Weathering grade according to Zurfluh et al. (2016).

Geochemistry: (C. Herd, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa19.3±0.3 (n=31); Low-Ca Pyroxene Fs16.7±0.2Wo1.5±0.1 (n=19).

Classification: Ordinary chondrite, H5. Petrologic type 5 based on well-delineated chondrules and plagioclase grain size (2-50 μm).

Specimens: A 30.4 g specimen, including one thin section, is at UAb. Main mass is with the owner.
