The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Toward a Cenozoic history of atmospheric CO2

open access: yesScience, 2023
The geological record encodes the relationship between climate and atmospheric carbon dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary transitions.

India-Asia collision as a driver of atmospheric CO2 in the Cenozoic

open access: yesNature Communications, 2021
Deep Earth degassing is a critical forcing factor for atmospheric CO2 variations and palaeoclimate changes in Earth’s history. For the Cenozoic, the key driving mechanism of atmospheric CO2 variations remains controversial.

Variable Phase Relationship Between Monsoon and Temperature in East Asia During Termination II Revealed by Oxygen and Clumped Isotopes of a Northern Chinese Stalagmite

open access: yesGeophysical Research Letters, 2022
Termination II (T‐II) is a natural reference for evaluating the potential effect of substantial ice sheets melting on monsoon and temperature changes caused by global warming.

The Holocene temperature conundrum answered by mollusk records from East Asia

open access: yesNature Communications, 2022
Scientists have been puzzled by the disparity between climate simulations of the past 12,000 years and geological records. Dong et al. reconstructed past annual and seasonal temperatures from land snail records to examine the potential seasonal bias.

A new diminutive fossil ziphiid from the deep-sea floor off northern Chile and some remarks on the body size evolution and palaeobiogeography of the beaked whales [PDF]

open access: yesActa Palaeontologica Polonica, 2023
The evolutionary history of the beaked whales (Ziphiidae), odontocetes nowadays adapted to deep diving, is well known thanks to a significant fossil record mainly from the deep ocean floors.

THE KULTUK VOLCANO: SPATIAL-TEMPORAL CHANGE OF MAGMATIC SOURCES AT THE WESTERN TERMINUS OF THE SOUTH BAIKAL BASIN BETWEEN 18 AND 12 MA

open access: yesГеодинамика и тектонофизика, 2015
The Kultuk volcano erupted at the axial South Baikal basin of the Baikal rift zone (BRZ). Now it exhibits facies of subvolcanic bodies, land-lava eruptions and subaqueous pillow lavas and hyaloclastites.

A review of amber and copal occurrences in Africa and their paleontological significance

open access: yesBSGF - Earth Sciences Bulletin, 2020
The paleontological interest for fossil plant resins (amber and copal) has greatly increased in the last decades, as field studies have resulted in the discovery of various new deposits worldwide.

CANYONS OF THE CHARYN RIVER (SOUTH-EAST KAZAKHSTAN): GEOLOGICAL HISTORY AND GEOTOURISM [PDF]

open access: yesGeo Journal of Tourism and Geosites, 2021
The Charyn River is located in South-East Kazakhstan, 195 km east of Almaty. The river valley cuts through Paleozoic rocks and loose sandy-clay deposits of the Cenozoic and forms amazingly beautiful canyons, the so-called "Valley of Castles".

The latest geodynamics in Central Asia: primary and secondary mantle melting anomalies in the context of orogenesis, rifting, and lithospheric plate motions and interactions

open access: yesГеодинамика и тектонофизика, 2017
A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting.
