Mineral Monday!
Is it glaucophane, chloritoid, or blue-green amphibole in Dutchess Co. NY? See our other social media feeds for more. By Donna Whitney et al.

It's not #ThinSectionThursday yet, but I have something exciting! Can you guess this mineral? (hint: very hard because this habit is uncommon)

Mineral Monday!
Presented here is a selection from Steinbilder (“Rock Pictures”), a series of digitally-worked abstract artworks by Roger Mitchell, using petrological images as a starting point.

A large (~10 cm X 15cm) "antique" glass-mounted thin section through a concretionary nodule ("bullion") shows dozens of small planispirally coiled and chambered shells clustered randomly together. The shells are in various orientations with respect to the plane of the section. In most, the inner whorls appear clear, with sediment or secondary mineral-fill in the outer (body chamber) portion. The irregularly shaped surrounding rock matrix is very dark in contrast. The roughly rectangular cover slip shows a thin rim of amber coloured adhesive. On the right side of the section, a scale graduated in millimetres indicates the overall size. A small circular label in the lower right reads, "JAMES LOMAX - PETROLOGIST" around the outer margin and, "MOSES GATE - BOLTON" in the centre. In the upper right, a small typed label ("No. 2.") is affixed. The section was likely produced sometime in the late 1800's or early 1900's.

#ThinSectionThursday my definition of pain: trying to identify minerals in a rock that's clinopyroxene + olivine + epidote (a very high grade marl entirely converted in calcsilicates). There is also probably wollastonite, plagioclase, garnet, and talc around
