👉 Glossitic is a type of rock that forms when magma from an eruption cools and solidifies in the Earth's crust. It is composed primarily of calcium, sulfur, and magnesium oxide. The term "glossitic" refers to its characteristic appearance, which consists of smooth, shiny surfaces and often has a yellow or orange hue due to the presence of iron oxides. This type of rock is found in many parts of the world, including Australia, New Zealand, and South Africa.
