Hiawatha Crator: A possible glimpse into the earth’s climate history

Image
 A 31Km wide impact crater in Greenland, known as the Hiawatha impact crater buried under ice was dated by researchers and has been stated that the meteorite impacted a few million years after the extinction of the dinosaurs and sheds new light on Earth's evolution in the post-dinosaur era.   Since 2015, when geologists from the University of Copenhagen's GLOBE Institute found the Hiawatha impact crater in north-eastern Greenland, there has been much controversy over the crater's age. The Natural History Museum of Denmark and the GLOBE Institute at the University of Copenhagen, as well as the Swedish Museum of Natural History in Stockholm, have conducted new analyses on grains of sand and pebbles from the Hiawatha impact crater, demonstrating that it is much older. In fact, according to a new study published today in the journal Science Advances, the crater is said to be 58 million years old. Dr Gavin Kenny of the Swedish Museum of Natural History said that "In the...

Field trip to Sanquelim reclaimed iron ore mine

Image
 A  Half-day field trip to sanquelim reclaimed iron ore mine for the students of the department of geology was organised to give the students an exposure of the mining industry. Sanquelim Mine is the only mine in Goa that has been Reclaimed successfully which is a legal requirement as per the laws  like ( MCDR 1966 ) governing the mining operations. The students got to witness how a mining site & its biodiversity can be restored back after the closure of mine. Co-ordinated by faculty members Ms. Swati Ghadi & Mr. Malcolm Afonso

Petrological studies of the Chandranath Granite South Goa

Image
  The Chandranath granite is a large 276 Sq.km wide crystalline body that covers the area from Betalbatim to Carmona in the coastal area and it extends till Loutolim and Sanguem. The Chandranath granite as per Gokul was placed stratigraphically placed at 2600 – 100 Ma younger than the Goa group of rocks. In the new classification of lithostratigraphy by A.G Dessai, it was identified as a basement for the Goa group of Rocks, the objective of this project is to study the variation in the mineralogical properties of the samples collected from the various outcrop of Chandranath granite and also study the associated structural features, the structural reading can be taken on the field and the samples which were collected will be studied in hand specimen and thin section.   The project is ongoing under the guidance of Ms. Swati Ghadi. By doing this project we got lots of experience in fieldwork, mapping techniques, and taking readings with different equipment like Brunton compass an...

A bird's eye view of a gorge in the East African Rift at Engaruka, Tanzania. The East African Rift system is a geological wonder of the earth. At which the two plates are constantly in motion and trying to split apart. Along the rift, a new continent is breaking away from the larger African landmass, this will give rise to the new ocean in the world. The formation of mountains along the Rift at Tanzania A Rift is a fracture on the earth’s surface that widens over time as an elongate basin bounded by opposed steeply dipping normal faults. The best example of Rift is an East African system that we are experiencing for the past 30 Ma years.   The political map of Africa showing countries The countries in the African continent are Algeria, Angola, Benin, Botswana, Burkina Faso, Burundi, Cabo Verde ,Cameroon, Central African Republic ,Chad, Comoros, Congo, Democratic Republic of the Congo, Republic of the Cote d'Ivoire, Djibouti, Egypt, Equatorial Guinea, Eritrea, Eswatini ,Ethiopi...

  Blue Agate Rock formation of Agate is very common. It consists of Chalcedony and Quartz as primary components; it comes in variety of colors. Agate is commonly formed within volcanic and metamorphic rocks. The use of Agate as an ornament can be dated back to 'Ancient Greece', it was used in assorted jewelry (found in various different colors) and in the seal stones of Greek warriors. This rock is of Chalcedony variety and has a chemical formula of SiO 2. On the Mohs scale of hardness, it stands between 6.5 to 7 with waxy luster and white streak. Its specific gravity ranges from 2.58-2.64 and having translucent diaphaneity.  According to the zodiac signs Agate is the birthstone of Gemini. The color blue represents truth, loyalty and reliability. It is believed to have healing abilities by the ancient people of Greece.
