Indialite is not known from the Eifel Mts. The photographs show cordierite, Cyclic twinning on (110) is producing the pseudohexagonal twins (similar to those of Aragonite)

Idem.

First photo shows "dorrite".

I agree; one complaint sent.

12th Dec 2006 07:10 UTCSaul Krotki Expert

My photo. Yes, I agree and sent an email to Uwe. It should be changed to cordierite in view of the cyclic twinning. It is the orthorhombic dimorph.

Thanks, fixed.

Hi Uwe,


I think we have to give up on the 52665 indialite as well. There are evident reenterant angles. Another cordierite.


Thanks for modifying the subtext as well.


This will leave us in dire need of any indialite photo!


With appreciation.

Thanks, Saul. Also fixed.
