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. 3

13. 5.NAGPUR-CHHINDWARA REGION Archaean rocks of Nagpur- Chhindwara area are called ‘ Sausor Group ’. 4.5 Km thick Highly Metamorphosed Intruded by plutonic igneous rocks. Chief rock types:- Hornblend -granulites, marbles, quartzites and garnetiferous schists . 13

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. 16

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

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. 18

19. STRATIGRAPHY 19 FORMATION LITHOLOGY Parsoi Feldspathic quartzite and conglomerate , phyllite . Agori Banded magnetite, quartzite, dolomite, calc-chlorite schist. -------unconformity------- Chitrangi Mafic and Ultramafic dykes. -------unconformity------- Dudhi Gneissic Complex Granite, Gneisses and Magmatite .

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

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. 24
