Description: | Heulandite is one of the zeolite group of minerals. It was named after John Henry Heuland, a mineral collector and dealer. Crystals of heulandite typically have a glassy to pearly lustre. This mineral is commonly found in cavities and vesicles (gas bubbles) in volcanic rocks such as basalt. This example is from Iceland, where there are extensive lava flows. Heulandite has a widespread distribution. Other localities include Poona in India, Scotland and Switzerland. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | beyond the North East rocks and minerals natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
