TEMPO.CO , Jakarta – Mass extinction events that killed dinosaurs were generally thought to be triggered by large asteroids that hit Earth 66 million years ago.

However, a new pair of studies believe that large volcanic eruptions may also play a role in the death of dinosaurs, as reported by Foxnews, February 23, 2019.

The study revealed about 66 million years ago, a large volcano erupting lava in India, now called Deccan Traps, burying many of the subcontinent under more than 11,000 basal feet (lava rock) and pouring toxic gases into the atmosphere, Eurekalert reported late. this week.

In one paper, they were able to determine the exact date for the eruption, noting “millions of years ago eruptions” sent lava hundreds of miles across India, creating the Deccan Traps basal flood.

“Now that we have determined the date of the Deccan Traps lava in more and different locations, we see that the transition seems to be the same everywhere,” UC professor Berkely Paul Renne said in a statement.

Researchers can use the argon-argon dating method to measure stones to determine when they came from. By using a new method, they were able to determine the date 66,052,000 years ago.

Assuming that most of the lava comes out after the collision, the gases entering the atmosphere might drip for a long time, similar to what is seen with Mt. Etna in Italy and Popocatepetl in Mexico.

In the case of K-Pg extinction, symptoms of significant climate change occurred before the peak of the volcanic eruption.

Courtney Sprain, lead author in one study, said the findings changed the role of Deccan Traps in the extinction of K-Pg, also known as extinction that occurred at the end of the Cretaceous Period.

A study published in January said the impact of asteroids caused tsunamis around the world to reach more than 5,000 feet in the air.

TEMPO.COJakarta – Peristiwa kepunahan massal yang membunuh dinosaurus umumnya dianggap dipicu oleh asteroid besar yang menghantam Bumi 66 juta tahun yang lalu.

Namun, sepasang studi baru percaya bahwa letusan gunung berapi yang besar mungkin juga berperan dalam kematian dinosaurus, sebagaimana dilaporkan Foxnews, 23 Februari 2019.

Studi itu mengungkap sekitar 66 juta tahun yang lalu, gunung berapi besar meletuskan lava di India yang sekarang disebut Deccan Traps, mengubur banyak anak benua itu di bawah lebih dari 11.000 kaki basal (batu lava) dan menuangkan gas beracun ke atmosfer, sebagaimana dilaporkan Eurekalert akhir pekan ini.

Kedua studi, yang diterbitkan dalam Science, melihat hubungan antara dampak terhadap Semenanjung Yucatan di Meksiko yang mungkin telah memicu letusan gunung berapi di India.

Dalam satu makalah, mereka dapat menentukan tanggal yang tepat untuk letusan itu, dengan mencatat “letusan jutaan tahun lalu” mengirim lava ratusan mil di seluruh India, menciptakan basal banjir Deccan Traps.

“Sekarang kami telah menentukan tanggal aliran lava Deccan Traps di lokasi yang lebih banyak dan berbeda, kami melihat bahwa transisi tampaknya sama di mana-mana,” kata profesor UC Berkely Paul Renne, dalam sebuah pernyataan.

Para peneliti dapat menggunakan metode penanggalan argon-argon untuk mengukur batu untuk menentukan kapan batu itu berasal. Dengan menggunakan metode baru, mereka dapat menentukan tanggal 66.052.000 tahun yang lalu.

Dengan asumsi sebagian besar lava keluar setelah tumbukan, gas-gas yang memasuki atmosfer kemungkinan menetes untuk jangka waktu yang lama, mirip dengan apa yang terlihat dengan Mt. Etna di Italia dan Popocatepetl di Meksiko.

Dalam kasus kepunahan K-Pg, gejala perubahan iklim yang signifikan terjadi sebelum puncak letusan gunung berapi.

Courtney Sprain, penulis utama di salah satu studi, mengatakan temuan itu mengubah peran Deccan Traps dalam kepunahan K-Pg, juga dikenal sebagai kepunahan yang terjadi pada akhir Zaman Kapur.

Sebuah penelitian yang diterbitkan pada bulan Januari mengatakan dampak asteroid menyebabkan tsunami di seluruh dunia mencapai lebih dari 5.000 kaki di udara.
