LOPOLITH Meaning and
Definition
-
A lopolith is a geological formation characterized as a concave-shaped intrusion of igneous rock that is wider than it is high. It is classified as a type of pluton, a large body of intrusive rock that forms beneath the Earth's surface. The term "lopolith" is derived from the Greek words "lopo," meaning basin or concave, and "lith," meaning stone or rock.
Lopoliths are commonly found in areas of tectonic activity, where molten magma rises from the Earth's mantle and intrudes into the overlying crust. When the magma solidifies underground, it forms a saucer-shaped body with a depressed central region, encompassed by parallel layers of igneous rock. The central depression is often filled with softer sediments, which can consist of various sedimentary formations.
These formations typically have a single, well-defined floor and an arched roof. The roof may display an irregular shape due to the uneven erosion of the surrounding rock. Lopoliths can vary greatly in size, ranging from a few kilometers to several hundred kilometers in diameter.
Geologists study lopoliths to gain insight into the geological history and composition of the Earth's crust. The formation of lopoliths can have important implications for the surrounding rocks and minerals, as well as for the development of mineral resources. Additionally, understanding the formation and composition of lopoliths contributes to our overall knowledge of plate tectonics and the dynamic processes that shape the Earth's surface.

Etymology of LOPOLITH
The word "lopolith" was coined in the late 19th century and comes from the combination of two Greek words: "lops" meaning "hinder" or "hind" and "lithos" meaning "stone". The term was introduced in geology to describe a particular type of intrusive igneous rock formation. In a lopolith, a saucer-shaped layer of magma is intruded between layers of sedimentary rock, often creating a dome or basin-like structure. The term emphasizes the position of the intrusion, which is lower or hindered compared to other igneous formations.
