Any suggestions on what this is? First thought was stilbite but have a few doubts.The formations measure between 4 to 6 cm in width. It is from Cape Split, Nova Scotia. Any help would be welcome...

I have considered scolecite due to the formation but the color throws me off.

Its not the right color for scolecite and scolecite crystal needles are distinct. Certainly looks like Stilbite. Its got the right color, and Stilbite does commonly form in that formation as well. While wheat sheaves are more prevalent, this radial form is frequent on stilbite.

The similarities between stilbite and heulandite were the first problem as both are prevalent in the area, just not in this formation which is why the scolecite question. It is an oddball. Thanks for your answer!
