Scientists find signs of geological activity on Venus

There is evidence that parts of Venus’ surface move in the same way as the Earth’s, scientists have said.

“We have identified a previously unrecognized tectonic deformation pattern on Venus, which is driven by inner movement just as it is on Earth,” said Paul Byrne, a professor at North Carolina State University, according to the UK broadcaster. BBC.

“Although different from the tectonics we are currently seeing on Earth, it is still evidence of an inner movement expressed on the planet’s surface,” Byrne added.

The report also states that scientists used data collected by NASA’s Magellan spacecraft from 1989 through 1994 to be able to describe surface structures. Researchers named these surface structures “campi”, from Latin for “field,” “campus,” the BBC reported.

“Traditionally, Venus’ lithosphere – its rocky outer layer – was viewed as a single continuous piece, unlike that of Earth, which is divided into a mosaic of moving tectonic plates,” the report adds.

However, the BBC reported that according to results published by the journal PNAS (Proceeding of the National Academy of Sciences), “the lithosphere of Venus actually has some degree of mobility – although not nearly as large as that of Venus. Earth “.

“The results of the computer models show that the molten rock – the magma – which agitates under the crust could produce the deformation, fracturing and distortion seen in Magellan images of the surface,” the report adds.

“The tectonic activity of Venus could therefore resemble that of the primitive Earth, during the Archean Aeon, between 4 and 2.5 billion years ago, when the heat flow within the planet was higher and the lithosphere thinner, ”the report adds.

According to research, the blocks – 100 to 1,000 kilometers (620 miles) long – also resemble the earth’s crust of the Chinese Tarim and Sichuan Basins, as well as the Australian Amadeus Basin and the Bohemian Massif under -jacent to much of the Czech Republic.
