Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 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.

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]
, 2004 Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

Dizhen xuebao, 2021 2010年智利马乌莱MW8.8地震发生在纳斯卡板块与南美板块的板块边界处，引起了显著的同震和震后效应。GPS台网数据显示记录到的同震海向位移最大约5 m，垂向沉降最大约50 cm。在经过对俯冲效应、季节变化等效应的校正后，震后6年的海向最大位移约68 cm，垂向抬升最大约20 cm。马乌莱地震显著的震后形变对该区域的地下三维黏弹性结构有良好的约束。本文建立了智利中南部俯冲带区域的三维有限元模型，黏弹性的地幔楔及海洋地幔均使用伯格斯体材料，并在断层面上设置2 km厚的软弱层以模拟震后余滑 ...

Elastic properties of silicate melts: Implications for low velocity zones at the lithosphere-asthenosphere boundary. [PDF]
, 2017 Low seismic velocity regions in the mantle and crust are commonly attributed to the presence of silicate melts. Determining melt volume and geometric distribution is fundamental to understanding planetary dynamics.

The westward drift of the lithosphere. A tidal ratchet? [PDF]
, 2018 Is the westerly rotation of the lithosphere an ephemeral accidental recent phenomenon or is it a stable process of Earth’s geodynamics? The reason why the tidal drag has been questioned as the mechanism determining the lithospheric shift relative to ...
