The Geological Survey of India (GSI) North Eastern Region (NER) installed two geological display boards at two important geological sites in Meghalaya.
a. Assam
b. Manipur
c. Tripura
d. Meghalaya
Details:
- The boards are unveiled at Meghalayas two important geological sites namely Mawmluh cave and Therriaghat, Sobhar in East Khasi Hill District.
- These geological display boards with geo-scientific information will help in creating awareness among visiting tourists, students and general public.
- They will help preserve site and also help future generation to be aware of such geological developments.
About Mawmluh Cave:
- Its importance was highlighted recently when high resolution stable isotopic studies of stalagmites from the cave showed that there was a major climatic event about 4200 years ago.
- The stalagmite in Mawmluh cave has been tagged as Global Stratotype Section and Point (GSSP). It makes it the first formally ratified marker of a geological time period in India.
- The Meghalayan Age period that began about 4200 years ago experienced an abrupt mega-drought and cooling around the world.
About Therriaghat:
- It marks the Cretaceous (K)-Palaeogene (Pg) mass extinction event.
- The Um-Sohryngkew (Wahrew) river section at Therriaghat is known for having the most complete records of Cretaceous-Palaeogene (K-Pg) boundary transition in India.
- There is also a high level of iridium metal from the boundary which marks a catastrophic event when a giant meteorite hit earth.
