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.
