Hand Sample: Dark gray, vesicular, glassy sample. Sample surface has a ropey texture with vesicles ranging from 0.01cm to 2.5cm in diameter. Sample has an iridescent luster on unweathered surfaces.

The intersertal ferrotholeiite samples are highly fractionated and were most likely emplaced before the gabbro of the formation. They have textures associated with rapidly frozen or highly viscous melts. KBR-7 through KBR-10 are also intersertal…

Hand Sample:

Composed entirely of Ilmenite.

Fine grained, collected from large boulder

Hand Sample:

Rock is comprised almost entirely K-Feldspar.

Recently exhumed ijolite from shallow bulldozer cut.

Hand Sample: Shows traces of iron oxidation in isolated areas. Small (> 0.5 mm in diameter) nodules, with the appearance of small sand grains appear in clusters on one face of the rock (not…
