sagenite

CRISPITE (a kind of Rutile, an ore of titanium = Sagenite)--CRISPATE (having a curled margin--in Botany and Zoology)

Moss, plume, sagenite and banded (fortification) agates are found throughout the country.

They are dull black, but most are partially coated by interlocking blades of lustrous red-brown, epitactic rutile (of the so-called "sagenite" habit), and a few plates seem to be nearly complete pseudomorphic replacements of hematite by rutile, overgrown, in turn, by a new generation of "sagenite." In Munich the R & TMinerals men had only a single flat of these peculiar specimens, and Jordi Fabre had a few more--but better supplies, we are told, may be forthcoming.
