The Industrial Might of Connecticut Pegmatite
The first feldspar mill in the state was operated by John C. Wiarda in South Glastonbury. All the early spar mills were waterpowered chaser mills. The spar was shoveled by hand beneath two vertical, moving stone wheels called buhrstones, whose great weight crushed the chunks to a fine powder as they rotated around a stone base called a chaser.

Interpreting and reporting 40Ar/39Ar geochronologic data GeoScienceWorld
The 40 Ar/ 39 Ar dating method is a variant of conventional KAr geochronology (Merrihue and Turner, 1966), whereby the radioactive parent isotope 40 K (t 1/2 ≈ Ga) undergoes branched decay to two stable daughter products, 40 Ca (∼89%) and 40 Ar (∼11%), via beta emission and electron capture, respectively (Beckinsale and Gale, 1969; Steiger and Jäger, 1977; Min et al., 2000).

Kfeldspar. Feldspars, like the Kfeldspar shown, have two cleavage directions. One is very good (meaning it is often easily observed) and the other better described as distinct (meaning it sometimes shows). The angle between the two feldspar cleavages is about 90 o, which explains why the specimen in Figure appears to have a square ...
