What was found in the deepest hole ever drilled?

fossilized microscopic plankton
6 km (20,000 ft) beneath the surface, scientists discovered fossilized microscopic plankton. What is this? A huge amount of hydrogen gas was also found, which came as a complete surprise. The drilling mud that came out of the hole was characterized as “boiling” because of how much hydrogen was in it.

Did the Kola Superdeep Borehole reach the mantle?

The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle. Among the more interesting discoveries: microscopic plankton fossils found at four miles down.

How far did the Kola Superdeep Borehole drill into the mantle?

approximately 7.5 miles
Known as the Kola Superdeep Borehole, the deepest hole ever dug reaches approximately 7.5 miles below the Earth’s surface (or 12,262 meters), a depth that took about 20 years to reach.

Is the Superdeep based on a true story?

‘Kola Superdeep’) is a 2020 Russian horror film directed by Arseny Syuhin, based on the real-life Kola Superdeep Borehole. The film focuses on a group of researchers and soldiers who investigate the mystery surrounding reports of a disease outbreak at a secret underground research facility in 1984 Russia.

Who dug the Kola Superdeep Borehole?

Russia’s Kola Superdeep Borehole was created by the Soviets in the name of science so they could learn more about what’s really under our feet and dig to depths unknown. The project to drill into the Earth’s surface began near Murmansk in the 1970s, when Soviet scientists wanted to learn more about the Earth’s crust.

What keeps the core of the Earth hot?

The primary contributors to heat in the core are the decay of radioactive elements, leftover heat from planetary formation, and heat released as the liquid outer core solidifies near its boundary with the inner core.

What is the deepest hole in the Earth’s history?

While the oil company didn’t find what it was searching for, the Bertha Rogers hole was the deepest hole for another five years. On June 6, 1979, however, a Kola borehole known as SG-3, broke the standing record. While the hole was only nine inches wide, in 1983 the hole reached a groundbreaking 39,000 feet into the crust.

What is the longest borehole in the world?

On June 6, 1979, however, a Kola borehole known as SG-3, broke the standing record. While the hole was only nine inches wide, in 1983 the hole reached a groundbreaking 39,000 feet into the crust.

How deep into the Earth was the Bertha Rogers hole?

During the process of getting oil, they drilled more than 31,000 feet underground which would be later called “Bertha Rogers hole”. They ended up drilling more than 6 miles into the planet’s surface.

How deep did the Kola borehole go?

Known as SG-3, one of the Kola boreholes broke that record on June 6, 1979. By 1983, the nine-inches-wide hole was able to penetrate an incredible 39,000 feet into the surface of the planet.
