Article
Full-text available
Reconstructing Cenozoic lacustrine astrochronology is essential for understanding climatic and environmental change around northeastern Tibetan Plateau. Existing models attribute the driving mechanism of regional precipitation and aridification to the Tibetan Plateau uplift and global climate change. However, in northeastern Tibet lacustrine astroc...
Article
The early Cambrian was a critical period of Earth history, marked by explosive diversification of metazoans and several profound changes in Earth's surface environments and global climate. A valid temporal framework for the early Cambrian Period and across the major bio-events is poorly constrained, and the key underlying forcings of million-year (...
Article
Among the predicted responses to ongoing climate warming is that coastal and inland areas may experience increasingly extreme weather, with potentially more droughts and floods. Such changes will have corresponding impacts on sedimentary systems. The Paleocene-Eocene thermal maximum (PETM, ∼56 Ma) was the most abrupt extreme warming event of the Ce...
Article
Two different hypotheses, glacioeustasy and groundwater aquifer eustasy, have been proposed to explain short-term, high-amplitude sea-level oscillations during past greenhouse-dominated intervals. However, the veracity of aquifer eustasy on long-term, high amplitude sea level has never been rigorously tested. We evaluate these competing hypotheses...

The end-Permian mass extinction event (∼252 Mya) is associated with one of the largest global carbon cycle perturbations in the Phanerozoic and is thought to be triggered by the Siberian Traps volcanism. Sizable carbon isotope excursions (CIEs) have been found at numerous sites around the world, suggesting massive quantities of 13 C-depleted CO 2 i...
Article
The timing and pattern of ecosystem recovery following the end-Permian mass extinction are still highly controversial, and a potential influence from orbital climate forcing is often not considered. To investigate this issue, a cyclostratigraphic analysis of an Anisian (Middle Triassic) marine platform succession (Guanling Formation, Yongning secti...
Article
The Middle Triassic is thought to have had a greenhouse paleoclimate with a few short humid phases. However, the timing of these humid events, and the extent to which orbital forcing influenced the evolution of climate, are unclear. Here, a cyclostratigraphic analysis has been carried out based on the integrated study of magnetic susceptibility, el...

Full-text available
The late Paleozoic ice age was one of the three major glaciations in the Phanerozoic. However, the influence and characteristics of this glaciation and deglaciation remain unclear. In this study, we present lithostratigraphy, biostratigraphy, and chemostratigraphy during the Late Mississippian to the Early Permian in Tarim, Northwestern China. Tari...
Article
Cyclostratigraphy plays a pivotal role in detecting and reporting Milankovitch cycles in sedimentary successions which allows for creating an independent astronomical time scale and estimates of sediment accumulation rates. In this study, cyclostratigraphic analysis of petrophysical logs from Lower Triassic Kangan Formation was performed in two wel...
Article
The Ediacaran is a highly dynamic period in terms of large perturbations in Earth's atmosphere, biosphere, and climate. Among these perturbations, a pronounced negative carbon isotope excursion, known as the Shuram excursion (SE), is characterized by the most depleted δ13C values (-12‰) that have ever been observed in the geological record. A poorl...

The Stuttgart Formation (traditionally called the Schilfsandstein) in the Germanic Basin (or Central European Basin) is a sand-rich episode representing the Mid-Carnian Episode within the gypsum-rich clayey semi-arid Keuper facies. That regional Mid-Carnian Episode is now recognized to be a manifestation of a significant global disruption of Earth'...

Borehole logging data are not yet systematically assessed using cyclostratigraphic methods. In order to obtain a reliable understanding of (long) borehole logging datasets, and especially data from complex settings, a good understanding of the potential and specifics of relevant (time/depth) evolutive methods in cyclostratigraphy are an essential p...

One of the clocks that record the Earth history is (quasi-) periodic astronomical cycles. These cycles influence the climate that can be ultimately stored in sedimentary rocks. By cracking these (quasi-) periodic sedimentation signals, high resolution astronomical time scale (ATS) can be obtained. Paleoclimate proxies are widely used to extract ast...

Refining reversal ages and improving reversal patterns for the Geomagnetic Polarity Time Scale (GPTS) is a major task for the paleomagnetic community. The Late Miocene is a period during which the geomagnetic field experienced frequent perturbations and dramatic environmental changes occurred. Thus, improved (sub)chron definition during this period...
Article
The astrochronology for the Early Triassic has been constructed from well-preserved marine successions; however, astronomical analyses of terrestrial strata have continued to be rare and problematic. Physical logs (natural gamma ray logging data) from two wells in the Junggar Basin, northwestern China cover the entire Lower Triassic terrestrial Bai...

Full-text available
Groundwater plays an important role in global water cycles and Earth’s climate system. Nevertheless, the geologic history of groundwater activity remains unclear due to limited data. Sphalerite colour banding in the Upper Mississippi Valley District (USA) is apparently caused by variation in oxidation state during precipitation which is controlled...
Article
Full-text available
Cyclostratigraphy is an important tool for understanding astronomical climate forcing and reading geological time in sedimentary sequences, provided that an imprint of insolation variations caused by Earth’s orbital eccentricity, obliquity and/or precession is preserved (Milankovitch forcing). Numerous stratigraphic and paleoclimate studies have ap...
Article
Full-text available
Recent studies demonstrate that aridification is sensitive to eccentricity forcing based on the northeastern Tibetan Plateau Cenozoic fluvio-lacustrine stratigraphic records. However, it is unknown whether this is a bias associated with the fact that higher frequency periods normally have larger age model uncertainties, which tend to decrease spect...

Acycle is a comprehensive and easy-to-use software package for time series analysis in paleoclimate research and education. It is designed to speed paleoclimate time series analysis, especially cyclostratigraphy, and to provide ob...
Conference Paper
Full-text available
Cyclostratigraphy is an integral part of many scientific studies on the age and duration of outcrop-and core material from sedimentary geoarchives. Yet, borehole data are not systematically assessed using cyclostratigraphic methods. This has various reasons, including (a) a specific resolution and commonly no possibility to increase data resolution...

Full-text available
In ancient hothouses lacking ice sheets, the origins of large, million-year (myr)-scale sea-level oscillations remain a mystery, challenging current models of sea-level change. To address this mystery, we develop a sedimentary noise model for sea-level changes that simultaneously estimates geologic time and sea level from astronomically forced marg...

In the aftermath of the Permian-Triassic mass extinction life experienced a prolonged recovery that lasted several million years. The full recovery of ecosystems dates back to the Middle Triassic Anisian Stage. However, the timeline for the early Triassic recovery is currently understood only in an uncertain framework. Here we present high-resoluti...

Project
This project will develop high-resolution time sequences, or chronostratigraphies, for the sedimentary rocks that carry a record of the Ediacaran (~555 Ma) Shuram negative carbon isotope excursion at two distant localities, one in South China and the other in South Australia. The chronostratigraphies will be determined by a new technique, rock magnetic cyclostratigraphy, which can detect global climate cycles that are driven by variations in the magnitude and direction of Earth's axial tilt and the ellipticity of Earth's orbit around the Sun. The astronomically-forced global climate cycles have been very regular throughout Earth history, so they provide a high-resolution metronome to develop time sequences for sedimentary rocks. The rock magnetic chronostratigraphies should provide up to 15,000 year resolution for the duration of the Shuram carbon isotope excursion recorded by the Doushantuo Formation in South China and by the Wonoka Formation in South Australia, both marine, silt-carbonate sedimentary rocks. Magnetizations applied in the laboratory to samples collected at close stratigraphic spacing (10-30 cm) will measure variations in the concentration of depositional magnetic minerals in the rocks. PIs previous work shows that the magnetic mineral concentration variations can record astronomically-forced global climate cycles. Oriented samples will also be collected from the Wonoka and Doushantuo rocks for standard paleomagnetic analysis to detect polarity reversals of the Earth's magnetic field. The reversal stratigraphy developed will help constrain the duration of the rock magnetically detected cycles to ensure they are astronomically-forced climate cycles. Comparing the rock magnetic cyclostratigraphies from two widely separated localities will provide a strong test of the primary nature of the Shuram carbon isotope excursion. Post-depositional alteration of the rocks is one explanation for the Shuram excursion. Identical high-resolution durations for the excursion in Australia and China would support a primary origin and would bolster the interpretation that the Shuram excursion is a singular event in Earth history and resulted from the oxidation of the world ocean just before life exploded into multi-cellular diversity. The development of the rock magnetic cyclostratigraphy technique for Ediacaran rocks that will result from this project will afford higher resolution relative time assignment for these ancient rocks than afforded by current geochronological techniques.

This project addresses the geologic time of the Triassic and the mechanisms of climate change. Chronostratigraphic models for the Triassic Period are active matters of debate with disagreements involving the durations of all of the stages. These disagreements are due in part to a lack of adequate cyclostratigraphic research and radioisotope dating that can provide biostratigraphy and magnetostratigraphy with absolute time constraints. Astronomically forced climate oscillations have been preserved in the Triassic sections that can be used as a high-resolution astronomical time scale. The astronomical time scale provides opportunities to decipher mechanisms of paleoclimate changes that occurred during the Triassic.
