Charnockites are named after the village of Charnock Hall in England, where this type of rock was first identified. They are typically coarse-grained and exhibit a wide range of colors, from pink to gray, depending on the mineral composition. Charnockites are commonly found in Precambrian metamorphic terrains and are considered to be a key component of the Earth's crust.
The Bharivar lava, named after the Bharivar rocks in the Western Ghats, represents a sequence of volcanic rocks that erupted during the Precambrian era. These lava flows are predominantly basaltic in composition and are characterized by their dark color and fine-grained texture. The Bharivar lava sequence is significant, as it provides insights into the volcanic activity and tectonic processes that shaped the Western Ghats during the Precambrian period.

The Western Ghats region is a part of the larger Indian Shield, a geological province that encompasses much of southern India. The region has undergone multiple phases of tectonic activity, including rifting, collision, and volcanism, which have contributed to its complex geological history. The charnockite and Bharivar lava sequences are products of these tectonic processes and offer valuable clues about the region's evolution. The Bharivar lava, named after the Bharivar rocks
Geochronological studies have provided a temporal framework for understanding the evolution of these rocks. The charnockites of the Western Ghats have been dated to around 2.5-2.7 Ga, while the Bharivar lava flows are believed to have erupted at around 2.2-2.3 Ga. The Western Ghats region is a part of
