Cryogenian interglacial greenhouse driven by enhanced volcanism: Evidence from mercury records

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 564 ()

An ice-free greenhouse interval (ca. 660 similar to 650 Ma) occurred between the global Sturtian (ca. 717Ma similar to 660Ma) and Marinoan glaciation ......

Unmixing deep-sea paleoclimate records: A study on bioturbation effects through convolution and deconvolution

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 564 ()

Marine sediments are typically subject to bioturbation from benthic macrofauna, which disrupt sediments and can have a substantial impact on the ampli......

Intermittent volcanic activity detected in the Von Karman crater on the farside of the Moon

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 569 ()

Sensitive to permittivity differences, lunar penetrating radar (LPR) can detect stratification due to material property differences in a medium. We ex......

Expanded lacustrine sedimentation in the Qaidam Basin on the northern Tibetan Plateau: Manifestation of climatic wetting during the Oligocene icehouse

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 565 ()

The Qaidam Basin in the core area of arid Inner Asia has been considered undergoing continuous aridification over the Cenozoic. However, the Qaidam Ba......

Vanadium isotope evidence for expansive ocean euxinia during the appearance of early Ediacara biota

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 567 ()

For reasons that remain unclear, the initial appearance of large, morphologically complex life on Earth seems to have taken place in deep-marine envir......

Ocean redox changes from the latest Permian to Early Triassic recorded by chromium isotopes

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 570 ()

Multiple observations have shown that widespread oceanic anoxia may have played an important role in the end-Permian mass extinction and delayed bioti......

Inverted channel belts and floodplain clays to the East of Tempe Terra, Mars: Implications for persistent fluvial activity on early Mars

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 562 ()

The climate on early Mars is one of the major unsolved problems in planetary science. It is unclear whether early Mars was warm and wet or cold and ic......

Eastward mantle flow field underneath East Asia quantified by combining shear-wave splitting orientations and absolute plate motion observations

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 566 ()

Although Earth's surface motion is well known, the flow field in the underlying mantle is not. Mantle flow is typically calculated on the basis of inf......

Dating individual several-km lunar impact craters from the rim annulus in region of planned Chang'E-5 landing: Poisson age-likelihood calculation for a buffered crater counting area

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 568 ()

The CE-5 lander was designed to retrieve a 2 m core of regolith for return to Earth. We attempt to date the most significant impact craters in the reg......

Using Zn and Ni behavior during magnetite precipitation in banded iron formations to determine its biological or abiotic origin

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 568 ()

There is longstanding controversy about the genesis of magnetite in banded iron formations (BIFs), particularly concerning whether it is of abiogenic ......

Southeastward dipping mid-mantle heterogeneities beneath the sea of Okhotsk

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 573 ()

The subduction history of the northwestern Pacific remains controversial. Small-scale heterogeneities in the lower mantle near subduction zone, common......

Qinghai-Tibet Plateau wetting reduces permafrost thermal responses to climate warming

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 562 ()

Permafrost, as one of the cryospheric indicators, is extremely sensitive to climatic changes. The Qinghai-Tibet Plateau has experienced remarkable war......

Was climatic cooling during the earliest Carboniferous driven by expansion of seed plants?

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 565 ()

The expansion of land plants is considered to have played a key role in triggering the Late Paleozoic Ice Age (LPIA), but evidence linking climatic ev......

North China block underwent simultaneous true polar wander and tectonic convergence in late Jurassic: New paleomagnetic constraints

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 567 ()

Jurassic witnessed two synchronous events on the Earth, named true polar wander (TPW) and closure of the Mongol-Okhotsk ocean (MOO) between Siberia an......

A novel tool to untangle the ecology and fossil preservation knot in exceptionally preserved biotas

期刊: EARTH AND PLANETARY SCIENCE LETTERS, 2021; 569 ()

Understanding the functioning of extinct ecosystems is a complicated knot of ecological, evolutionary, and preservational strands that must be untangl......
