It is 50 years since the landmark paper where Black et al.(1971) presented whole-rock Pb-
Pb and Rb-Sr isotopic evidence for some rocks in Greenland surviving from Earth's first …

The presence of exposed land on the early Earth is a prerequisite for a certain type of
prebiotic chemical evolution in which the oscillating activity of water, driven by short-term …

For decades, deep sea hydrothermal vents have been a preferred setting for the Origin of
Life, but “The Water Problem” as relates to polymerization of organic molecules, together …

The origin of life is one of the most fundamental questions of humanity. It has been and is
still being addressed by a wide range of researchers from different fields, with different …

It has long been recognized that the stable oxygen isotope 18 O/16 O ratios of chemical
sediments show a systematic decrease with increasing age. This continuous, 3.8 Ga long …

Recent discoveries of geyserite and siliceous sinter with textural biosignatures in the∼ 3.5
Ga Dresser Formation of the Pilbara Craton, Western Australia, extended the record of …

Paleoarchean stromatolites are among the oldest compelling evidence for life. We present
advanced two-and three-dimensional (2-D and 3-D) reconstructions of the morphology …

This study investigates the paleobiological significance of pyritic stromatolites from the 3.48
billion‐year‐old Dresser Formation, Pilbara Craton. By combining paleoenvironmental …

The chemical and isotopic compositions of Precambrian Fe-rich chemical sedimentary rocks
have figured prominently in discussions on the Fe biogeochemical cycle and redox …

The shallow marine and subaerial sedimentary and hydrothermal rocks of the~ 3.48 billion‐
year‐old Dresser Formation are host to some of Earth's oldest stromatolites and microbial …
