Green Apophyllite with White Stilbite in Geodesque Huelandite
Dimension: 8cm x 6.5cm x 6cm
Locality: Deccan Traps, Jalgaon District, Maharashtra, India.
A unusual geodesque formation featuring Green Apophyllite with white Stilbite in a slabby Huelandite Matrix. A complex piece that makes beautiful from every angle.
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 its pastel colours and beautiful crystal formations.
