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 Americans to teach laboratory chemistry. He made significant contributions to the measurement of atomic weights.
Co-Type Localities:
Isostructural with:
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').
See also borocookeite.
