3.7" Apophyllite on Multi-Colored Heulandite - Sakur, India

 
 
 
This is a unique association of green, bipyramidal apophyllite crystals that formed in association with white and green heulandite crystals. The earthy green tones of the heulandite can be attributed to inclusions of celadonite, a mineral of the mica group. This mineral association was collected from Maharashtra, India.

This specimen comes from the Deccan Traps (a large igneous province and one of the largest volcanic features on earth) in the Pune Province of India. In the course of quarrying for other materials or digging wells sometimes large pockets of zeolites and other minerals are unearthed in the volcanic rock.

Apophyllite while not a zeolite itself is almost always found associated with zeolites in the same pockets. It has two crystal habits, a rectangular prism capped by a steep four sided pyramid or a pseudo-cubic structure. While not a well known mineral to the general public it is popular among mineral collectors due to it's pastel colors and beautiful crystal formations.
