About CookeiteHide

Josiah Parsons Cooke

Formula:

(LiAl₄◻)[AlSi₃O₁₀](OH)₈

Colour:

White, yellowish green, greenish, pink, brown, grey, rarely lilac

Lustre:

Waxy, Greasy, Pearly

Hardness:

2½ - 3½

Specific Gravity:

2.58 - 2.69

Crystal System:

Monoclinic

Member of:

Chlorite Group

Name:

Named in honor of Josiah Parsons Cooke Jr. (12 October 1827, Boston, Massachusetts, USA - 3 September 1894, Newport, Rhode Island, USA), Harvard mineralogist and chemist. A largely self-taught chemist, he was one of the first Americans to teach laboratory chemistry. He made significant contributions to the measurement of atomic weights.

Co-Type Localities:

ⓘ Mount Rubellite Quarries, Mount Rubellite, Hebron, Oxford County, Maine, USA

Isostructural with:

Chlorite Group

Characteristic botryoidal to worm-like aggregates show radial pattern of plates, occasionally showing pearly lustre of basal cleavage.

Forms a solid-solution series with (Li-free) donbassite.

A natural Na analogue may exist (see 'UM1969-13-SiO:AlHNa').
