Review of colloids in ore genesis Open
Advances in the theory of colloidal chemistry over the past decade indicate that this state of matter may take part in ore forming processes to a far greater extent than is at present generally recognised. The stability of a colloidal sol …

The biological and chemical evolution of the Baltic Sea Basin reflected in changing sulphide geochemistry. Initial results from IODP Exp. 347 Open
The trace element chemistry of anoxic sediments and sedimentary rocks has previously been shown to correlate with the chemistry of the ocean (Algeo., 2004). Recent studies have used the traceelement content of ancient sedimentary pyrite to…

Primary metal enrichment at the black-shale hosted Talvivaara Ni-Zn-Cu-Co-U deposit, Finland: links to Paleoproterozic seawater? Open
The 2 billion tonne, black shale hosted Talvivaara Ni-Zn-Cu-Co deposit appears unique withregards to its metal endowment and formation. Denoting the Talvivaara-type deposit(Loukola-Ruskeeniemi, 1991) there are no known analogues of this 2.…

Cycles of nutrient trace elements in the Phanerozoic Ocean and relationship to atmosphere-ocean oxygenation Open
Redox sensitive and nutrient trace element (TE) concentrations in the palaeo-ocean have commonly been interpreted to rise abruptly toward the end of the Neoproterozoic, and remain relatively constant through the Phanerozoic. This pattern h…

Using sedimentary pyrite chemistry to inform regional exploration for sediment-hosted gold deposits - a gold fertility case study from the Selwyn Basin Area, Yukon Open
Regional-scale exploration for sediment-hosted gold deposits is hampered by the challenge of evaluating the fertility of ancient sedimentary sequences that host these deposits. Recent developments in laser ablation inductively coupled plas…

Do hyperenriched black shales correspond with periods of elevated atmospheric O 2 Open
Hyperenriched black shales (HBS) contain anomalously high levels of organic carbon and a wide variety of trace elements, in particular Mo, Se, Zn, Ni, Cu, U, and V, and, in some cases, Cr, Co, Ag, Au, PGE, and REE. The source of metals has…

Accumulation of trace elements into black shale - how to identify a viable source rock for orogenic and Carlin-style gold deposits Open
Newly published models suggest that some orogenic and Carlin-style gold deposits formed by the remobilisation of trace elements during interaction with hydrothermal or metamorphic fluids from early sedimentary pyrite that was enriched in A…
