EducationSkeletonized septarian nodule

1st May 2016 16:37 UTCcynthia peterson

Is there an actual name for a septarian nodule that has eroded away, leaving only the internal crystal structure?


I've seen terms like skeletonized septarian, septum, septaria, and melikaria. The melikaria is giving me trouble- Journals list it as chemical deposits separate from septarian nodules from Quaternary formations in TX. But I've found a paleontology lesson that lists them as the internal structure of a septarian.


So is there a official name?



Thanks,

Cynthia

Welcome to Mindat, Cynthia.


If I understand you correctly that you are talking about what is shown in the photo below, I believe the name that was given to these structures was "Melikaria" after the grandmother of the person who found these originally in Mexico. That's about as much as I know......

I found this, but can't quote from it.

Yeah I found the same journal, hence the confusion. The picture Paul posted is what I'm talking about.
