Writeup from MB 102:

Jungo 004        40°57.306’N, 118°21.031’W

Humboldt County, Nevada, United States of America

Found: 15 Aug 10

Classification: Ordinary chondrite (H6)

History: A single stone was found by Mr. Scott Johnson on the north side of the Jungo dry lake bed on August 15, 2010. Two pieces of this stone were donated to Cascadia in July 2011.

Physical characteristics: The stone has a dark brownish-black exterior which represents a combination of weathered fusion crust and weathering rind. The cut face is reddish-brown and shows visible cracks and pits.

Petrography: (M. Hutson, Cascadia). The thin section is extensively cross-cut by fractures and weathering veins and heavily stained. Chondrules grade into a granular recrystallized matrix and ~10% of feldspar grains >=50 µm across. Metal and troilite heavily weathered. Many of the sulfide grains contain numerous angular silicate clasts concentrated towards the outer edge of the sulfide. Deformation of olivine is variable (S1-S5), with S3 material dominating the section.

Geochemistry: (M. Hutson, Cascadia) Olivine (Fa20.6±0.6, n=22) and low-Ca pyroxene (Fs18.3±0.7Wo1.4±0.2, n=20).

Classification: Likely paired with Jungo 002 and Jungo 003.

Specimens: 21.0 g in three pieces and a polished thin section are on deposit at Cascadia. Mr. Scott Johnson holds the main mass.
