Gold in Ophiolites [PDF]

open access: yes, 2004
Ophiolites, as a class, have been currently under-estimated as potential gold targets, although they have been the subject of major scientific research. Their resources have also attracted investors producing Cr, Cu (massive sulphides), Co, Ni (laterites), industrial rocks and minerals (serpentinites, emeralds), etc. They are also potential PGE sources.

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.

Supra-subduction zone ophiolites: The search for modern analogues

open access: yes, 2003
The development of ideas on modern analogues for ophiolite complexes can be divided into three parts. In the first (1963 to 1972), ophiolites were mainly viewed as on-land analogues of the crust and upper mantle formed at mid-ocean ridges.

Geodynamic setting and models of the emplacement of ophiolitic allochthons in the structure of accreted island arcs of the pacific north-western framing

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2019
Based on the model of an oceanic island-arc breakup followed by accretion of rear and frontal parts of an arc to a continental margin of North-East Asia, the geodynamic nature of the ophiolites of Kamchatka and South Koryakia has been considered.

Ophiolite complex of Piedmont-Ligurian basin (Northern Apennines)

open access: yesГеофизический журнал, 2023
The Northern Apennines contain remnants of the Piedmont-Ligurian Basin (PLB) or ocean, which during the Late Mesozoic time (mainly in the Jurassic) separated the paleo-Europe (Iberian plate) from the southern paleocontinent Adria at the Africa promontory.
