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.

Characterizing the physical properties of rocks from the Paleozoic to Permo-Triassic transition in the Upper Rhine Graben

open access: yesGeothermal Energy, 2018
Geothermal energy exploitation in the Upper Rhine Graben currently targets high-temperature anomalies in the crystalline Paleozoic basement at depths up to 5 km. However, at certain locations (e.g.

Fault systems in multiply deformed regions of Eurasia

open access: yesRussian Journal of Earth Sciences, 2023
We have studied the orogenic fragile deformation of the upper Earth’s crust of several areas of the Eurasian continent, where deformations have occurred many times – in the Tian Shan and Altai-Sayan regions of the Central Asian Paleozoic Fold Belt and in

An Unusually Warm Upper‐Crust in the Late Paleozoic North China Continental Arc: Implications for the Thermal Modification of the Giant Bayan Obo REE Deposit

open access: yesEarth and Space Science, 2023
The genesis and timing of formation of the giant Bayan Obo deposit, the world's largest rare earth element (REE) deposit in the western part of the late Paleozoic northern North China continental arc (NCA), are highly controversial due to complex mineral

The Upper Paleozoic Floras, Their Succession and Range [PDF]

open access: yesThe Journal of Geology, 1909
Diastrophism and floral changes.-The terrestrial plant is inseparably dependent on the conditions, not only of the soil and the water, but also of the air from which it derives an important part of its substance. Any change, therefore, in the climatic, terrestrial, or water conditions of its environment directly affects the plant and causes morphologic
