Marialite from
Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA

Locality type:Park
Classification
Species:Marialite
Formula:Na4Al3Si9O24Cl
Comments:Radiating bundles of columnar, acicular to fibrous crystals found in the amphibolite and along the contact with the topaz-quartz-fluorite veins associated with phologpite. Some veins contain mostly albite, marialite, quartz, calcite, and clinochlore with minor fluorite.

"Radiated scapolite occurs in quartz, intimately associated with pink to purple fluorite, in blocks of material in the dump of the upper mine. The scapolite is faintly brownish-white in color and has a somewhat wax-like luster. The aggregates are coarse to fine columnar and are made up of elongated prismatic crystals from 1 to 5 millimeters in diameter, which sometimes reach 6 centimeters in length. These prisms only rarely exhibit well-defined prismatic planes and are never terminated in the specimens collected. The fluorite, which is intimately intergrown with the scapolite, is in part rose pink and in part deep purple, the colors varying abruptly." (Shannon, 1921b).
