One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Iron formations (IF) represent an iron-rich rock type that typifies many Archaean and
Proterozoic supracrustal successions and are chemical archives of Precambrian seawater …

Although it is not known when or where life on Earth began, some of the earliest habitable
environments may have been submarine-hydrothermal vents. Here we describe putative …

Rare earth elements and yttrium (REY) have a distinct distribution pattern in seawater, and
this pattern may be faithfully preserved in carbonate sediments and rocks. Anomalous …

The determination of La and Ce anomalies in natural waters, biological samples and
biogenic sedimentary rocks can provide unique information on biogeochemical processes in …

The record of the continental lithosphere is patchy and incomplete; no known rock is older
than 4.02 Ga, and less than 5% of the rocks preserved are older than 3 Ga. In addition, there …

We present data for the rare earth elements and yttrium (REY) in the National Research
Council of Canada natural river water reference material SLRS-4 and 19 natural river waters …

A first study of REE+ Y distribution in a variety of Neoproterozoic (Cryogenian and
Ediacaran) carbonates from different settings in the Saldania, Gariep, Damara and West …

The distribution of the rare earths and yttrium (REY) in co-existing hydrous Mn oxides and Fe
oxides that form marine hydrogenetic ferromanganese crusts is used to better describe the …

The chemical composition of surface water in the photic zone of the Precambrian ocean is
almost exclusively known from studies of stromatolitic carbonates, while banded iron …
