Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 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.

Uma síntese sobre o magmatismo alcalino do Paraguai Oriental [PDF]
, 2013 Alkaline magmatism occurs in six distinct areas of Paraguay and forms bodies of variable size, shape, composition and age. The oldest rocks are found in the north and correspond to the Permo-Triassic Alto Paraguay Province (241 Ma). Four Early Cretaceous

Large igneous provinces and mass extinctions: an update [PDF]
, 2014 The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best ...

Melt-induced buoyancy may explain the elevated rift-rapid sag paradox during breakup of continental plates [PDF]
, 2018 The division of the earth’s surface into continents and oceans is a consequence of plate tectonics but a geological paradox exists at continent-ocean boundaries.

Magnetotelluric studies from two contrasting Brazilian basins: a reassessment of old data [PDF]
, 1993 Before the mid-1980s large numbers of magnetotelluric (MT) data were collected and interpreted without addressing the possible effects of near-surface (e.g. static) distortion contributions.

Atmospheric K-feldspar as a potential climate modulating agent through geologic time [PDF]
, 2017 Clouds and aerosols have a large, yet highly uncertain, effect on changes in Earth’s climate. A factor of particular note is the role played by ice-nucleating particles, which remains poorly understood.

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]
, 2011 Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.
