📌Coral Reef Fossils In Ladakh: 🔸Geologists have made a remarkable discovery of coral reef fossils at an elevation of 18,000 feet above sea level in the Burtse region, Eastern Ladakh Himalayas 🔸These fossils reveal the existence of ancient coral colonies and provide insights into a previously unknown geological past of the Burtse region, suggesting the presence of a diverse marine ecosystem. 🔸The findings support the idea that the Himalayas emerged when continental plates were thrust out of the Tethys Sea about 40 million years ago. 🔸The discovery of coral reef fossils in Ladakh is significant because it indicates that this region, now a high-altitude desert, was once submerged under a vast ocean. 🔸This finding offers insights into Ladakh’s geological history, the impact of tectonic activity, and ancient climate conditions

🔆Kopili fault zone ✅Recently, researchers from the Indian Institute of Geomagnetism (IIG) have identified seismogenic liquefaction features in the active Kopili Fault (KF) zone. ✅It is a 300 km long and 50 km wide lineament situated in the northeastern region (NER) of India. ✅It extends from the western part of Manipur to the tri-junction of Bhutan, Arunachal Pradesh, and Assam. It is closer to Himalayan Frontal Thrust. ✅This is a seismically active area falling in the highest Seismic Hazard Zone V. ✅It is associated with collisional tectonics because of the Indian Plate subducting beneath the Eurasian Plate. ✅The fault itself is a transpressional fracture that generates lower crustal dextral strike-slip earthquakes. ✅A tectonic depression filled up by the alluvium of the Kopili river and its tributaries, the Kopili fault zone has witnessed many seismic activities in the past including the 1869 earthquake (7.8 magnitude) and the 1943 earthquake (7.3 magnitude).

🔘Alcalus Fontinalis In News Researchers have discovered a new species of frog, Alcalus fontinalis in the northeast Indian state of Arunachal Pradesh recently. About ▪️The identification of the new species is based on molecular, morphological, and osteological characteristics. ▪️Alcalus fontinalis frog was formally named Alcalus fontinalis, meaning “spring or fountain,” referencing the tiny streams or brooks where the frog was found in Arunachal Pradesh. ▪️It was discovered in the Namdapha Tiger Reserve, Arunachal Pradesh. ▪️The new species stands out from its congeners due to a unique combination of morphological features. ▪️It has a disc on the fingers and toes with a horizontal/transverse groove on the dorsal surface. ▪️It has wrinkled dorsal skin. ▪️It has a pair of faint dorsolateral stripes on the back. ▪️The frog appeared to be a mix of a bush frog and a water frog.

#International_Organizations #Trick_Mnemonic Mnemonic for G7 economies:- All G7 countries are wealthy nations. So, they all drink JUICE & have GF (girlfriend). So, its JUICE GF : J- Japan U- USA I- Italy (not India, plz pay attention) C- Canada (not China, plz pay attention) E- England (United Kingdom) G- Germany F- France Note: (i) European Union is also a part of this group which is represented by above mentioned European Countries. (ii) Intially, it was G6, when formed in 1975. Later, in 1976, Canada was added. And again in 1997, Russia was added. So, it became G8. But, due to annexation of Crimea in 2014, Russia was suspended and hence it became G7. Chronology: G6 ➖ G7 ➖ G8 ➖G7.
