Volcanogenic features of IOCG deposits of North Carajás, Brazil, and related constraining evidence

open access: yesJournal of the Geological Survey of Brazil
The magnetitic Cu-Au (IOCG) deposits of north Carajás, Amazonian Craton, Brazil, are hosted in the Neoarchean (2.76 Ga), dominantly basaltic-greywacke Itacaiúnas metavolcanic-sedimentary sequence that evolved in a continental rift setting.

Organization of the Zletovo’s Pb-Zn deposit mineral and anthroghene access databases, Republic of Macedonia [PDF]

open access: yes, 2016
The Republic of Macedonia has been and still is one of the leading European lead-zinc producers. One fraction of that lead-zinc production comes from the Zletovo lead-zinc mine, near the city of Probistip in eastern parts of the country. Our latest paper

Carbonate alteration of ophiolitic rocks in the Arabian–Nubian Shield of Egypt: sources and compositions of the carbonating fluid and implications for the formation of Au deposits [PDF]

open access: yes, 2016
Ultramafic portions of ophiolitic fragments in the Arabian–Nubian Shield (ANS) show pervasive carbonate alteration forming various degrees of carbonated serpentinites and listvenitic rocks.

Metallogeny of Greenland

open access: yesOre Geology Reviews, 2016
Abstract Greenland is the largest island on Earth, with 80% of its area covered by a thick ice sheet. The coastal areas are underlain by variable rocks ranging from Eoarchean to the most recent ages. Greenland has a mineral exploration tradition since its colonization in the 18th century, and mining of cryolite started in 1854.

Impacts of Coastal Underground Brine Exploitation on the Depletion of Shallow Brine in Beach and Neritic Zones

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Coastal underground brine (CUB) exploitation and groundwater discharge jointly drive the depletion of beach and neritic shallow underground brine (BNSUB). BNSUB is crucial for CUB exploitation, yet its reserve remain unquantified, and the impacts of different mining models on its evolution are poorly understood.

Unraveling the Enrichment Mechanisms of Rare Earth Elements in Deep‐Sea Sediments: An Environmental Magnetic Perspective

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.
