This document discusses the distribution, stratigraphy, and economic importance of Archaean rocks in Madhya Pradesh, India. It describes how Archaean rocks are well exposed in several regions of India including South India and Madhya Pradesh. Within Madhya Pradesh, Archaean rocks are found in the Nagpur-Chhindwara region, Bilaspur-Balaghat region, Mahakoshal region, and Baster region. These rocks have significant economic importance as sources of important minerals like manganese, iron, and copper ores. Archaean rocks also provide building materials and are a major source of India's geodiversity.

3. 1.INTRODUCTION
• Archean (or Archaean) comes from the ancient
Greek, meaning "beginning, origin".
• Its earliest use is from 1872, when it meant "of
the earliest geological age.
• The Archean spanned Earth's early history from
its formation about 4,540 million years ago until
2,500 million years ago.

Archaean rocks of Peninsular India have been
devided into five zones:-
• Archaean rocks of South India.
• Archaean rocks of Eastern Ghats.
• Archaean rocks of M.P. and Maharashtra.
• Archaean rocks of Bihar and Orissa.
• Archaean rocks of Rajasthan.

called ‘Sausor Group’.
• 4.5 Km thick
• Highly Metamorphosed
• Intruded by plutonic igneous rocks.
• Chief rock types:-
 Hornblend-granulites, marbles, quartzites and
garnetiferous schists.

16. 7.CHILPI GHAT SERIES
• The schistose rocks of Chhattisgarh basin.
• Wedge in at the eastern end between the Vindhyans
and Granitic gneisses.
• Expands westward into two strips.
 Northern: Nagpur-Chhindwara.
 Southern: Nagpur-Bhandara.
• Chief rocks type:-
 Quartzite, Shale and Slate.

17. 8.SONWANI SERIES
• Northern Balaghat.
• Chief rock types:-
 Crystelline limestone, quartz-magnetite-
schist, calc-silicate, phyllite, muscovite-schist,
manganese-ore.

18. 9.MAHAKAUSHAL REGION
• From Jabalpur (M.P.) to Sonbhadra (U.P.).
• 600Km long, 20Km wide.
• The northern most boundary marks the Son-Narmada North Fault
and Son-Narmada South Fold demarcates the southern boundary..
• Separated from the Balaghat region by streach of Deccan traps.
• Chief rock types:-
 Conglomerate, phyllites, mica-schists, chert, marbles, manganese
and iron ores.

20. 10.BASTER REGION
• Southern Chhattisgarh.
• Both igneous and sedimentary origin.
• Consist mainly of schists and gneisses.

22. 11.ECONOMIC IMPORTANCE
• Archaean rocks are always important source
of economic important minerals.
• If we remove the minerals of this rock from
India’s geodiversity, we left with only coal,
petroleum, diamond, bauxite, laterite and
some kind of soils.
• Manganese ore are deposited in gondite,
kondurite rich laterite.
22

23. • Minerals related to gondite found in Balaghat-
Chhindwara region (sausor group).
• Important iron-ore deposits present in
archaean rock of central india.(Durg, Baster,
Chanda and Ratnagiri).
• Copper deposition is also present in Balaghat
region.
• Some important non matellic minerals are also
found here(e.g. in pigmatite)
23

24. • There’s a lot of diversity in rocks, granite,
charnockite, gneiss, schists and limestone are
used for building and ornamental materials.
