Axinite-(Fe) from
State Route 2 roadcut, Marlborough, Hartford Co., Connecticut, USA

Locality type:Road Cutting
Classification
Species:Axinite-(Fe)
Formula:Ca2Fe2+Al2BSi4O15OH
Comments:"Beautiful groups of tabular crystals, up to an inch across, were associated with prehnite and several other minerals in a small cavity in gneiss. The largest group was almost three inches long. Most of the crystals were colored green by inclusions of chlorite, but some were of a typical lavender-brown tint and quite gemmy. Pseudomorphs of chlorite after axinite were fairly abundant. This is the first reported occurrence of axinite in Connecticut." Schooner (1958)

"Groups of simple axe-shaped crystals, up to two inches across, were embedded in loose chlorite, with some admixed clay. The crystals were of two types: lavender-brown, glassy, and without inclusions, and greenish, opaque, and thoroughly impregnated with the chlorite. Some of the smaller examples of the latter kind were pseudomorphs of chlorite after axinite. In all cases, there seemed to be two generations of axinite crystals, differing in size but not in habit. One large crystal had a number of smaller ones clustered on its surfaces." Schooner (1961)
Habit:tabular, axe-head shaped
Colour:lavender-brown
Quality for species:Good crystals or rich for species - important (!)
Abundance at site:Common
