Onset of plate tectonics by the Eoarchean
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 …

Biosignatures on Mars: what, where, and how? Implications for the search for martian life
The search for traces of life is one of the principal objectives of Mars exploration. Central to
this objective is the concept of habitability, the set of conditions that allows the appearance …

Microbially Induced Sedimentary Structures Recording an Ancient Ecosystem in the ca. 3.48 Billion-Year-Old Dresser Formation, Pilbara, Western Australia
Microbially induced sedimentary structures (MISS) result from the response of microbial
mats to physical sediment dynamics. MISS are cosmopolitan and found in many modern …

Recognition of ocean plate stratigraphy in accretionary orogens through Earth history: A record of 3.8 billion years of sea floor spreading, subduction, and accretion
Ocean plate stratigraphy (OPS) is a term used to describe the sequence of sedimentary and
volcanic rocks deposited on oceanic crust substratum from the time it forms at a spreading …
