Geology controls the features of the land-mass and is well marked by dividing Gujarat state physiographically into the following three distinct geographical units: (a) Main land Gujarat, (b) Peninsular Gujarat (the Saurashtra), and (c) Kutch. 2. MAINLAND GUJARAT. The geology of India is diverse. Different regions of India contain rocks belonging to different geologic periods, dating as far back as the Eoarchean of the rocks are very deformed and deposits include recently deposited alluvium that has yet to undergo diagenesis. Mineral deposits of great variety are found in the Indian subcontinent in huge quantity.

Precambrian - Precambrian - Precambrian geology: By international agreement, Precambrian time is divided into the Archean Eon (occurring between roughly billion years ago and billion years ago) and Proterozoic Eon (occurring between billion and million years ago).

After the Precambrian, geologic time intervals are commonly subdivided on the basis of the fossil record.

Vadodara district, Gujarat (falls under latitude and longitude 22o16’” – 22o21’” N and 73o28’” – 73o38’” E respectively). The study area belongs to Khandia formation of Champaner group, Aravalli Supergroup having meso-proterozoic age. The region has experienced polyphase.

Considered as the paradise of Indian geology, the region is central to the understanding of geology of the Precambrian Indian Shield and Phanerozoic cover successions.

The book is also amongst the most illustrative treatise on the geology of a region published in recent years. Rajasthan is endowed with a continuous geological sequence of rocks from the oldest Archaean Metamorphic, represented by Bhilwara Supergroup (> m.

Abstract. The Champaner Group, earlier designated as the Champaner Series, constitutes the youngest unit of the Aravalli Supergroup. It consists of a sequence of meta-subgreywacke, sandy phyllite, graphite schist, protoquartzite, polymictic meta-conglomerate, dolomitic limestone and manganiferous phyllite (Gupta et al.

in Mem Geol Surv India –, The Aravalli Mountain Range is a northeast-southwest trending orogenic belt in the northwest part of India and is part of the Indian Shield that was formed from a series of cratonic collisions.

The Aravalli Mountains consist of the Aravalli and Delhi fold belts, and are collectively known as the Aravalli-Delhi orogenic belt. The whole mountain range is about km long. Rajasthan forms north-western part of the Indian Shield.

The State exposes a variety of litho logical and tectonic units ranging in age from Archaean to Recent times. Before going into details of Geology of Rajasthan, let us first see, geology time in general to make sense of terms in geology.
