Concept notes: Peninsular Gneiss is one of the oldest rock formations in India, dating back to the Archean Eon. It is a metamorphic rock that is found in various parts of the Indian peninsula, including Bangalore. In Bangalore, this rock formation is prominently displayed in Lalbagh Botanical Garden, which is a significant geological and botanical landmark.
Explanation: Peninsular Gneiss is a type of metamorphic rock that is one of the oldest rock formations in India, dating back to the Archean Eon, which spans from 4 billion to 2.5 billion years ago. This rock formation is found in various parts of the Indian peninsula, including Bangalore. The Peninsular Gneiss is characterized by its banded structure and is formed through the high-temperature and high-pressure metamorphism of igneous rocks.
In Bangalore, the Peninsular Gneiss is prominently displayed in Lalbagh Botanical Garden, which is a significant geological and botanical landmark. Lalbagh is not only known for its diverse collection of plants and trees but also for its geological significance. The rock formation in Lalbagh provides a tangible connection to the ancient geological history of the region, making it a valuable site for both educational and research purposes.
The presence of Peninsular Gneiss in Lalbagh Botanical Garden is a testament to the geological history of Bangalore and the broader Indian peninsula. This rock formation is a key indicator of the region's ancient geological processes and the transformation of the Earth's crust over millions of years. Visitors to Lalbagh can observe and study the Peninsular Gneiss, gaining insights into the geological history of the area and the broader context of the Indian subcontinent.
It is important to note that while Peninsular Gneiss is found in Lalbagh, other locations in Bangalore and the surrounding areas may also contain this rock formation. However, Lalbagh is the most prominent and accessible site for studying and observing this ancient rock type in Bangalore. The geological significance of Lalbagh makes it a valuable resource for students, researchers, and enthusiasts interested in the geological history of the region.
In summary, the Peninsular Gneiss rock formation is prominently displayed in Lalbagh Botanical Garden, making it the correct answer to the question. This location is a significant geological site that provides a tangible connection to the ancient geological history of Bangalore and the Indian peninsula.
