Description

Details

Plagioclase Feldspar and Talc specimen from Otta in Southern Norway. Feldspar is the most abundant mineral in Earth's crust, comprising over 40% of the total estimated mass. This variety, Plagioclase is the Sodium/Calcium rich variety of Feldspar, providing a pale pink colour. Talc is another abundant mineral, notably it is the index mineral for number 1 on Moh's hardness scale - which means it is one of the least scratch resistance minerals on Earth; it is extremely friable and can leave a smooth, dusty trail on your hands once touched - this is not dangerous and is actually good for your skin! This specimen is perfect for laboratory or classroom analysis, as it shows the symbiosis of 2 abundant and siginificant silicate minerals in one specimen. Also ideal for a collection revolving round Norwegian minerals or silicates. Each specimen is provided with a white card tray and information label.
