👉 The term "thranitic" refers to a type of metamorphic rock that is composed primarily of iron and nickel, with elements such as silicon, boron, and vanadium. This type of rock is highly ductile, meaning it can be easily shaped and molded into various shapes without breaking or cracking. The term thranitic rocks are often found in the Earth's crust, where they are formed through the cooling and solidification of iron-rich igneous rocks.
