Heulandite with Celadonite

specimen number:
2062438

location:
Sakur Quarry, Sangamner, Ahilyanagar, Nashik, Maharashtra, India

description:
Sharp crystals of heulandite measuring to 1.5 cm in size across the top of matrix. These are bluish green in color due to the presence of celadonite. In great condition. From the early 2000's.

Sakur Quarry, located near Sangamner in the Ahilyanagar and Nashik region of Maharashtra, India, is a commercial and mineral excavation site operating within the vast Deccan Traps basalt formations, though precise formal opening and closing dates for the quarrying operations are not historically documented. Geologically, the area is characterized by Cretaceous to Eocene flood basalts where secondary mineral crystallization occurred within gas cavities and vesicles. The notable heulandite specimens found at this locality feature distinctive green to bluish-green hues, which are caused by microscopic inclusions of celadonite trapped inside the growing zeolite crystal structures during hydrothermal activity.
