Peninsular Gneiss or Peninsular Gniessic Complex are the gneissic complex of the metamorphics found all over the Indian Peninsula, on top of which, the supra-crustal Dharwar System have been laid down. [1] The term was first fashioned by W.F.Smeeth of the Mysore Geological Department in 1916 based on the first scientific study of this rock ...
The Peninsular Gneiss is a sequence of Archean gneisses found throughout the Indian Shield and ranging in age from 3400 to 2500 million years old. [23] [24] Etymology
The Lalbagh hill is composed of dark biolite gneiss of granitic to granodioritic composition containing streaks of biolite. Vestiges of older rocks are seen in the form of enclaves within the gneiss. Peninsular Gneiss of the region is dated 2500 to 3400 million years that accreted in three major episodes, i.e. 3.4 Ga, 3.3–3.2 Ga and 3.0–2.9 Ga.

A considerable area of peninsular India, the Indian Shield, consists of Archean gneisses and schists which are the oldest rocks found in India. The Precambrian rocks of India have been classified into two systems, namely the Dharwar system and the Archaean system (gneiss and schists). The Dharwar System
The North Kyangsong Province gneiss samples indicated ages to 2.12 billion years ago and in 1985, the Sangni Metamorphic Supergroup and the Sangni Revolution were proposed as names for the gneiss-schist and gneiss formation. These groupings have been used to make sense of the 2.1 billion year old Punchon Granitic Gneiss, the Wonnan Group and ...
The bedrock is not nearly as metamorphosed as the surrounding gneiss bedrock and is therefore of interest for answering how the Earth's surface appeared billions of years ago. There is a massive magnetite resource in this area. There are large deposits of rare-earth oxides at Kvanefjeld.
