Scientists have found the halogen levels in the meteorites that formed the Earth billions of years ago are much lower than previously thought. The post Meteorite analysis shows reduced salt is key in Earth’s new recipe appeared first on HeritageDaily - Heritage & Archaeology News.
An international group of scientists, with the participation of the University of Granada (UGR), has shed new light on the origin of gold, one of the most intriguing mysteries for Mankind since ancient times and which even today doesn't...Show More Summary
A team of researchers from the University of Cambridge have developed a new way of measuring the pressure inside volcanoes, and found that it can be a reliable indicator of future eruptions. The post ‘Bulges’ in volcanoes could be used to predict eruptions appeared first on HeritageDaily - Heritage & Archaeology News.
In 1857, guided by the flickering light of a candle deep in a cave at Naracoorte in South Australia, the Reverend Julian Tenison-Woods stumbled across thousands of tiny bones of rodents and small marsupials buried at the base of crystal...Show More Summary
Large reservoirs of magma stored deep in the Earth's crust are key to producing some of the Earth's most powerful volcanic eruptions, new research has shown. The post Deep magma reservoirs are key to volcanic ‘super-eruptions’, new research suggests appeared first on HeritageDaily - Heritage & Archaeology News.
Researchers in the USA and Japan say they may have found the cause of the first mass extinction of life. The post Large volcanic eruption may have caused the first mass extinction appeared first on HeritageDaily - Heritage & Archaeology News.
Parts of the ice of the Juvfonne snow patch in Jotunheimen are 7600 years old, which makes it the oldest dated ice on mainland Norway. The post Norway’s oldest ice found in central Norway appeared first on HeritageDaily - Heritage & Archaeology News.
Diamonds may be ‘forever’ but some may have formed more recently than geologists thought. A study of 26 diamonds, formed under extreme melting conditions in the Earth’s mantle, found two populations, one of which has geologically ‘young’ ages. The post Diamonds show Earth still capable of ‘superhot’ surprises appeared first on HeritageDaily - Heritage & Archaeology News.
The Sahara is the world's largest desert and dust source with significant impacts on trans-Atlantic terrestrial and large-scale marine ecosystems. The post Dust deposits give new insights into the history of the Sahara appeared first on HeritageDaily - Heritage & Archaeology News.
Volcanic eruptions such as Mount St. Helens' in 1980 show the explosiveness of magma moving through the Earth's crust. The post Research opens fresh view on volcanic plumbing systems appeared first on HeritageDaily - Heritage & Archaeology News.
Earth is estimated to be around 4.5 billion years old, with life first appearing around 3 billion years ago. The post A map that fills a 500-million year gap in Earth’s history appeared first on HeritageDaily - Heritage & Archaeology News.
At the Triassic-Jurassic boundary, 200 million years ago, some 60% of species living on Earth disappeared. Scientists suspected that magmatic activity and the release of CO2 were responsible for this environmental disaster.
Sedimentary layers record the history of the Earth. They contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia, thereby enhancing our ability to understand and predict the evolution of our planet.
The Earth's mantle -- the layer between the crust and the outer core -- is home to a primordial soup even older than the moon. Among the main ingredients is helium-3 (He-3), a vestige of the Big Bang and nuclear fusion reactions in stars. And the mantle is its only terrestrial source.
We know that since Charles Darwin's time. Based on observations made during the Beagle's voyage, he correctly formulated that sinking islands start to be fringed by rings of coral reefs, leading to atoll formation.
The ice sheet covering Greenland is four times bigger than California -- and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. Today, sea levels are rising and the melting of Greenland is a major contributor. Understanding how fast this melting might proceed is a pressing question for policymakers and coastal communities.
200 million years of geological evolution of a fault in the Earth’s crust has recently been dated. Published in Nature Communications, these new findings may be used to shed light on poorly understood pathways for methane release from the heart of our planet.
A new study published in Geology uses pockets of melts trapped within crystals to understand the conditions occurring beneath volcanoes before explosive eruptions.
Way before trees or lichens evolved, soils on Earth were alive, as revealed by a close examination of microfossils in the desert of northwestern Australia, reports a team of University of Oregon researchers.
In a paper published in Proceedings of the National Academy of Sciences (PNAS) Saint Louis University researchers report new information about conditions that can cause the earth's tectonic plates to sink into the earth.
