Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 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.

Occurrence and cycling of trace elements in ultramafic soils and their impacts on human health: A critical review [PDF]

open access: yesEnvironment International, 2019
The transformation of trace metals (TMs) in natural environmental systems has created significant concerns in recent decades. Ultramafic environments lead to potential risks to the agricultural products and, subsequently, to human health.

A global forum on ultramafic ecosystems: from ultramafic ecology to rehabilitation of degraded environments

open access: yesEcological Research, 2018
Abstract The 9th International Conference on Serpentine Ecology (ICSE) was held in Tirana and Pogradec (Albania) from June 5 to 9, 2017. More than 100 delegates from 29 countries around the world gathered to present their research on recent advances in: (i) ultramafic soils, (ii) biogeochemistry, (iii) diversity of ultramafic flora ...

The Ultramafic Belts [PDF]

open access: yes, 2013
One petrological approach to upper mantle studies is to determine which ultramafic rocks represent mantle material. Ultramafic rocks occur in a variety of field and petrographic associations: in recent reviews, Wyllie [1967b, 1968] outlined eleven petrographic associations, some with subdivisions.

The seed germination properties of two hyperaccumulator plant species with the potential for Ni agromining [PDF]

open access: yesBotanica Serbica, 2023
The aim of this study is to investigate the effect of different nickel concentrations and light in combination with storage conditions and storage time on the seed germination ability of two serpentine-endemic nickel hyperaccumulating species ...

Specific leaf area is lower on ultramafic than on neighbouring non-ultramafic soils [PDF]

open access: yesPlant Ecology & Diversity, 2022
Specific leaf area (SLA) is a core trait within the leaf economic spectrum that describes differences in plant performance and productivity. Research on the sources of variation in the leaf economic spectrum and SLA has primarily focused on climate. Much

Contribution of ultramafic rocks in central Sanandaj-Sirjan zone to the characterizing of physio-chemical condition during initiation of subduction [PDF]

open access: yesپترولوژی, 2018
In the central part of the Sanandaj-Sirjan zone, there is an ultramafic rock exposure (hornblendite and pyroxenite) adjacent to Molataleb felsic complex completely located between Azna and Aligoodarz towns.
