Lepidolite from
Anderson No. 1 Mica Mine, East Hampton, Middlesex County, Connecticut, USA
| Locality type: | Mine | |
| Classification | ||
|---|---|---|
| Species: | 'Lepidolite' (not an IMA approved species) | |
| Formation: | Primary | |
| Comments: | Abundant in the lepidolite-cleavelandite zone. Shannon (1920) gives best overall description - "Some masses are composed of bright small scales of a beautiful deep purple-pink color, intergrown with fine platy cleavelandite stained yellow brown by iron, the contrast in colors yielding very showy specimens. Other coarser scaly masses are pale lavender to gray in color and much of the material shows small spheres up to the size of a pea composed of folia of grayish lepidolite embedded in white cleavelandite." Hess et al (1943) describe the lepidolite as "globular radial aggregates ranging from less than 1/4 inch to 3/4 inch in diameter". They analyzed the lepidolite for alkali metals and reported that a "visual estimate from the spectrographic pattern of the lepidolite gave K2O, 5.0; Na2O, 1.0; Li2O, 5.0; Rb2O, 3.0; Cs2O, 1.0" percent. | |
| Habit: | granular, as globular radial aggregates | |
