A xenolith ("foreign rock") is a rock fragment (country rock) that becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term xenolith is almost exclusively used to describe inclusions in igneous rock entrained during magma ascent, emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose … WebJan 2, 2024 · How do xenoliths form? The rock that forms from cooled magma is called igneous rock. Xenoliths are different types of rock embedded in igneous rock. As the molten material rises, it tears off bits and pieces of the magma pipe in which it is traveling. These bits and pieces, trapped in the magma but not melting into it, become xenoliths.

WebNov 20, 2012 · Geologists call it relative dating — we know which one is older but do not know how old they are. Inclusions of foreign rocks that are found in igneous rocks are named xenoliths. So we can also say that kersantite contains xenoliths of granite. The same principle is also used in relative dating of sedimentary rocks. WebHow do xenoliths form? Xenoliths are torn from country rock from deep cracks, or magma pipes, in the Earths surface as magma rises. The country rock is trapped in the magma but not melting (assimilating) into it.
