2020 impact factor announced for Geochemical Perspectives Letters

Following publication of the 2021 Journal Citation Reports, we are pleased to announce that the impact factor of Geochemical Perspectives Letters (GPL) has risen to 5.567, consolidating its place among the top journals in geochemistry.

The editors and editorial office thank all of the authors, reviewers and readers who have contributed to the success of GPL.

Latest Elements issue: Speleothems

Growing slowly drip by drip through the millennia, stalagmites, stalactites, and flowstone—collectively known as speleothems—are some of the most fantastic mineral features in nature. Speleothems are also critical archives of past environments, and their study incorporates expertise from groundwater hydrogeology and geochemistry, atmospheric chemistry, climate science, geobiology, and even geophysics. Research on speleothem trace element and isotopic geochemistry, constituent organic compounds, noncarbonate minerals, and morphology can help illuminate paleoenvironmental conditions and document historical anthropogenic land-use changes. This issue of Elements will introduce the many ways that speleothems are used within the geoscience community to learn about natural Earth processes and our role in modifying them.

All EAG members have online access to current and past issues of Elements.

207Pb-excess in carbonatitic baddeleyite as the result of Pa scavenging from the melt

For the last two decades, the end of the voluminous phase of eruptions of the Siberian Traps large igneous province has been constrained by a U-Pb date of discordant baddeleyite collected from the Guli carbonatite intrusion with the assumption...

Black shale Mo isotope record reveals dynamic ocean redox during the Mesoproterozoic Era

Eukaryotes reached ecological importance in the late Neoproterozoic Era, some one billion years after their emergence. Their slow rise to prominence has been ascribed to prolonged environmental stagnation, but testing...

Geochemistry Making the News: Goldschmidt Special

Unexplained cache of prehistoric SHARK TEETH is discovered at a 2,900-year-old site in the City of David - 50 miles from where these fossils would be expected to be found

[DailyMail] Scientists have found an 'unexplained' cache of fossilised shark teeth at a 2,900-year-old site in the City of David, Jerusalem. The mysterious collection, consisting of 29 teeth in all, dates back 80 million years – making them as old as the late dinosaurs. Researchers say they were found at least 50 miles (80 km) from where such objects would be expected – in the desert...

Atomic arsenic key to gold concentration

[AustralianMining] French scientists have dived deeper than ever before into gold and arsenic’s relationship, improving the understanding of gold concentration and how it can be recovered more effectively. Using intense X-ray machines from the European Synchotron in France, the researchers probed the chemical bonds between gold and minerals containing iron...

Diamonds really are forever: Study

[7news] Ancient diamonds indicate earth was primed for life's explosion at least 2.7 billion years ago, researchers say. Volatile gases conserved in diamonds discovered in ancient rocks were present in similar proportions to those found in the earth's mantle, which lies between the planet's core and crust. This indicates there has been no fundamental change in the...

Civilization May Have Collapsed in 1200 B.C.E. but the Silver Trade Didn’t, Researchers Discover

[Haaretz] Before the invention of coinage bearing images of religious icons, emperors and local egomaniacs, the peoples of the prehistoric southern Levant were using bits and bobs of practically pure silver as money, or as pre-money, depending on whom you ask. It is perhaps ironic that the silver the ancient Israelites and their predecessors in the region used had itself...

New Method To Identify Dirt Helps Track Criminals

[Forbes] "Knowledge of Geology. – Practical, but limited. Tells at a glance different soils from each other. After walks has shown me splashes upon his trousers, and told me by their colour and consistence in what part of London he had received them.” - Dr. Watson’s description of Holmes’s abilities in “A Study in Scarlet“ Scientists at the National Centre for Forensic Studies...

Racial minorities 'systematically excluded' from geology and climate change sciences

[] Climate change and the geosciences risk being seen as largely "white sciences" in the Global North, according to a new study. The research shows that racial minority students are significantly underrepresented in Geology and other sciences of relevance to climate change. Presenting the work at the Goldschmidt Geochemistry conference...

This One Planetary Feature May Be Crucial For The Rise of Complex Life in The Universe

[ScienceAlert] The way a planet is tilted on its rotational axis with respect to its orbital plane around a star - what we know as 'axial tilt' - could be key to the emergence of complex life. According to a new study, a modest axial tilt, like Earth's, helps increase the production of oxygen, which is vital for life as we know it - and planets with tilts that are too small or too large might not...

Barrage of city-sized asteroids peppered Earth between 2.5B, 3.5B years ago

[UPI] According to new research, scheduled for presentation Friday at the Goldschmidt Geochemistry Conference, Earth was struck by a city-sized asteroid an average of once very 15 million years between 3.5 and 2.5 billion years ago -- a rate 10 times higher than earlier estimates. Though...
