Improving Mindat.orgSteacyite page - crystallographic data incorrect

15th May 2026 07:00 UTCHerwig Pelckmans OP
Right now is mentioned:
Morphology: Elongated along [001] and showing only the forms {100} and {001}.
(this was incorrectly copied from the HOM)Suggested correction:
Morphology: Elongated along [001] and showing mainly the forms {100} and {001}, and sometimes {110} and/or {101} (Pelckmans, 2026, pers. comm.).

Morphology: Elongated along [001] and showing only the forms {100} and {001}.
Yes, the word "only" is unprecise and will be edited. It is refering to the most common prismatic habit, which may occasionally also display the form {110}. The more rare dipyramidal habit however are showing {100}, {001) and {101}.
see f.ex.
