Precambrian according to the chronostratigraphic chart 2013 is considered as a Super eon in which Hadean, Archean, and Proterozoic are considered as eon. Archean and Proterozoic are divided into 4 and 3 eras respectively. Cenozic era is divided into Paleogene, Neogene and quaternary periods. Archean or simply Precambrian geology of India include Early Precambrian deposits are: Gorur gneiss (3300-3400 Ma) Sargur Supracrustals (3100-3300 Ma) Granulites block of Southern India (>3200-250Ma) Dharwar Supergroup (2600-2800 Ma) Aravalli Supergroup (2000-2500 Ma). Late Precambrian deposits: Delhi Supergroup Cudappah Supergroup Vindhyan Supergroup Singhbhum craton, Sausar and Sakoli group Dharwar craton which includes Dharwar supergroup are classified as Dharwar super group of Western Dharwar craton (WDC) and eastern Dharwar craton (EDC) In which WDC have the Dharwar supergroup succession as follows Charnokites Younger granite ---------------------unconformity-------- Chitradurga group --------------------------------------------------- in which Chitradurga and Bababudan is considered as the Darwar supergroup of WDC Bababudan Group --------------------------------------------------- Peninsular gneiss ---------------------------------- Sargur group ----------------------------------------- Gurur Gneiss Pangaea was still intact even at the end of Permian(Paleozoic era). It started breaking up in the early Mesozoic which resulted in the origin of Tethys sea between the Laurasia and Gondwanaland. Carboniferous is part of PALEOZOIC ERA. CRETACEOUS is the last stage of the Mesozoic era during which the Deccan traps started outpouring the lava on to the Indian plate. The man like apes started appearing somewhere around 5 million years ago. NOTE: Panchet lies in Jharkhand

please use some different colour in PPT as sometimes it is impossible to read from PPT...btw great video for geography optional .

Thank you madam. Your lectures are fascinating me. keep on !

good explanation of eras.mam explained periods like plistocene,Pliocene,mayocene,oligocene

Ma'am thank you so much building confidence. ... Greatful to attached you..

very helpful video mam, thankyou so much.

Very well explained !!!

Best video for the topic.

Really good information

Awesomeness....

Thanks so much ma.. Really helpful

Is there any lecture of time, space, and causality in geomorphology please suggest me.

Really good

thanks fir this lecture

Carboniferous is in paleozoic and Cretaceous in mesozoic.

Thank you.

well explained

THANK YOU

Mam any notes or video available for preparation of mining inspector

I am regular follower of ur channel and benefitted a lot while preparing upsc with geography optional.thanx one again. Regarding this video ,mam i was aspecting little concept based lecture where i could understand how these systems formed with more use of maps in every sytem and passing phases. Although this lecture is brilliant but it is more factual rather than conceptual.if possible please improve this video i d be grateful to u. Thank u mam and best regards. Dhiraj

+Dhiraj Prakash Thanks for the feedback. We have included this video as part of Indian Geography. For aspirants of earth sciences CSIR (especially) we will include indepth conceptual lectures shortly, where we would be discussing the these topics in further detail again.

mam it's very usefull for us plz explain distribution of minerals in india

Great lecture mam very informative, there is one thing which i will like to point out you are reading gneiss as genesis it is pronounciated as 'nice' reading only the neiss part

Thanku maim very help full vedio

thank you

many thanks mam

Thank you mam

thank you medam

For standard stratigraphic time scale can we write this information as Indian equivalence...??

Thks Bec of u ma dout clear

Ma'am, thank you so much for your lecture. Can you recommend books for me to follow for Geology Optionals for the Indian Forest Service Exam. I would also need a list of books for Forestry Optional. Many thanks.

Mam I was very much greatful to see your videos and learn many things first of all I would like to say big thanks.and I was studying geology and expert in Indian stratigraphy I wish to suggest there r small mistakes in your lecture, carboniferous period is comes in paleozoic age and creataceous period is famous for deccan lavas which are now exposed as deccan traps, in cenozoic age there are 5 periods they are paleocene, Eocene, Oligocene, Miocene, pliestocene, and pliestocene is great ice age period. iam not pointing out you mam iam just giving information for readers.

There was certainly an ice age during the Carboniferous (The Karoo Ice age) and its impact on the Indian subcontinent is very much evident in Talchir sediments

U r awsm

if a question comes on geological structure of india in UPSC examination for 20 marks what all needs to b dere in the answer. im mentioning all the rock systems as well as about the peninsular , extra peninsular region plus indo gangetic plain, but this is making my answer very lengthy in rock system we have to mention about them in just 2 or 3 lines or explain them with their characteristics along with the region and minerals. pls do let me know how tp write an answer for this. Discuss the geological structure of india. :)

hi mam i am regularly watching ur videos i have a simple request plz make a sequence in ur lectures which i find missing for example u are explaining the Indian monsoons first and then composition and structure of the atmosphere

+NIVAS KUMAR Questions can be asked on evolution of Indian Subcontinent (you can include the geological perspective along with the plate tectonics and other theories), you could be asked to classify India based on Eras and Periods.
