Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 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.

The Geology of Aquitards in Alluvial Aquifers: A Predictive Approach Based on Facies Models. [PDF]

open access: yesGround Water
We review facies models for alluvial aquifers and demonstrate how they can be used to predict aquifer and aquitard continuity in three dimensions. We provide case studies illustrating how facies models can be used to improve groundwater investigation and remediation outcomes.

Alluvial soil formation in the plains of northeastern Brazil [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2020
Soils in alluvial plains of the lower course of the Acaraú River, Ceará State, Brazil, are weakly developed and have a complex distribution in the landscape. This study reports the pedogenic characterization of such soils in an effort to understand their

Natural variability of major and trace elements in non-ornithogenic Gelisoils at Edmonson Point, northern Victoria Land, Antarctica [PDF]

open access: yesPolish Polar Research, 2018
Antarctica is perceived as one of the most pristine environments on Earth, though increasing human activities and global climate change raise concerns about preserving the continent’s environmental quality. Limited in distribution, soils are particularly

Characterization of geological profiles developed in geoenvironments of the Cruzeiro do Sul Formation, southwestern Amazon

open access: yesBoletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2021
The diversity of soils and environments in the Amazon demands studies that improve the information with regard to their use and management. The objective of this study was to characterize the morphological, physical and chemical attributes of soils ...

Stop 2 Kainui silt loam and Naike clay, Gordonton Rd [PDF]

open access: yes, 2008
At this stop are several remarkable features both stratigraphic and pedological, and a “two-storied” soil, the Kainui silt loam alongside (in just a few places) the Naike clay. Both soils are Ultisols. The sequence of tephra beds and buried soil horizons

Silt-sized sediments and gypsum on surface formations in the Ebro Basin: a disambiguation of the term “gypsiferous silts”

open access: yesGeologica Acta, 2021
The term “gypsiferous silts” has been used since the 1960s by many authors, but it has relied on unclear, am-biguous criteria that attributed aeolian, colluvial or alluvial origins to these materials.

Characteristics of Andisols Developed from Andesitic and Basaltic Volcanic Ash in Different Agro-Climatic Zones

open access: yesSoil Systems, 2022
This study aimed to identify the characteristics of Andisols under tea plantations affected by different Oldeman’s agro-climatic zones, of different ages, and containing different types of volcanic ash material.

Role of Arthropods in Maintaining Soil Fertility

open access: yesAgriculture, 2013
In terms of species richness, arthropods may represent as much as 85% of the soil fauna. They comprise a large proportion of the meso- and macrofauna of the soil.
