• An ophiolite is a segment of ocean crust and mantle tectonically exposed on land by obduction (over thrust), usually when an ocean basin closes.
• An ophiolite sequence consists of variably altered oceanic rocks, including marine sediments, ocean crust, and part of the mantle.
• The name ophiolite means “snakestone” from “ophio” (snake) and “lithos” (stone) in Greek.
• The rock sequence is named for the brilliant green, snake-like serpentine minerals which form in altered ocean crust and mantle.
• Ophiolites are rare but nonetheless found throughout the world.
• Notable ophiolites are found in Cyprus, the northwestern US, the Alps, Papua New Guinea, and Oman.
• Idealized Ophiolite Suite is rarely found in Nature.

Hi,where we found chromite deposits in ophiolites??which is best area in ophiolites for chromite mining??

[@geetapodili7375]

Diabase/ Dolerite is a hypabyssal equivalent of intrusive gabbro and extrusive basalt, formed at shallow depths

[@muhammadshah1984]

Your topic was part of my commission exam.

[@muhammadshah1984]

Thank you for Ophoilite topic.

[@poojasaini4213]

Very informative lecture.

[@rajjatmanhas3801]

Doing great work

[@Geo_Mind]

Thanks Bro. 🤘

[@vinayaksoni4279]

This video is part of any lecture series?? I request you to make lecture on stratigraphy 🙏

[@Geo_Mind]

No this is a separate video.

[@rajinder2662]

Ravinder Kumar ki book best

Sir can u please upload a video on mid oceanic rich basalt formation

[@abhijeetsuryawanshi6731]

thank you sir, helped alot :)

[@muhammedfarsin1663]

sir, can you make lectures on metamorphic petrology

[@Tvmasala123]

Sir i have got an assignment on PETROGENESIS OF OPHIOLITES . Is this content is right for assignment?

[@Geo_Mind]

Yes

[@catchlifewithmylife7698]

thank you sir please sab like kare

[@naiduram6930]

Sir what does mean ophiolites petrogenesis, have we write about MORB petrogenesis regarding ophiolites

[@Geo_Mind]

Please refer to JD winter, I can't explain it here.

[@naiduram6930]

Yes sir

[@naiduram6930]

Petrogenesis in jd winter they aren't mentioned about Ophiolites petrogenesis they gave only about MORB petrogenesis so I'm asking Are MORBS petrogenesis nd Ophiolites petrogenesis is samr

[@Geo_Mind]

@@naiduram6930 Yes essentially, this Inhave discussed in the video, how the are formed

[@naiduram6930]

Okay sir Thank you so much

[@poojapareek8056]

Plz can you share the website from where u collect this material related ophiolite

[@Geo_Mind]

Hi pooja I have used multiple resources, so pinpointing one website won't help

[@supriyaagrahari2590]

Sir unable to find it's pdf on telegram.plzz provide it

[@Geo_Mind]

Hi please download the App on-app.in/app/oc/300373/uwcsj?Dcopy-link%26Dtutor-course-referral%26Dcourse-overview-app

[@studywithadarsh2019]

Please upload metamorphic texture or structure

[@Geo_Mind]

soon

[@adityasingh6396]

Sir can u share the pdf of this Lecture?
