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 environments, including… Expand
High-Temperature and High-Pressure Crystal Chemistry
Cradle of Life: The Discovery of Earth's Earliest Fossils
One of the greatest mysteries in reconstructing the history of life on Earth has been the apparent absence of fossils dating back more than 500 million years. We have long known that fossils of… Expand
A new window into Early Archean life: Microbial mats in Earth's oldest siliciclastic tidal deposits (3.2 Ga Moodies Group, South Africa)
Newly discovered sedimentary structures produced by ancient microbial mats in Early Archean sandstones of the 3.2 Ga Moodies Group, South Africa, differ fundamentally in appearance and genesis from… Expand
Crystal structure and compressibility of zircon at high pressure
Effects of temperature and pressure on the crystal structure of forsterite
- R. Hazen
- 1 December 1976
The crystal structure of synthetic forsterite has been studied as a function of temperature and pressure. Crystal structures have been refined from three-dimensiona l diffraction data collected at… Expand
Bulk modulus—volume relationship for cation-anion polyhedra
A bulk modulus—volume relationship is demonstrated for cation coordination polyhedra in a variety of structure types including oxides, silicates, halides, sulfides, phosphides, and carbides: Kp… Expand
An actualistic perspective into Archean worlds - (cyano-)bacterially induced sedimentary structures in the siliciclastic Nhlazatse Section, 2.9 Ga Pongola Supergroup, South Africa.
Extensive microbial mats colonize sandy tidal flats that form along the coasts of today's Earth. The microbenthos (mainly cyanobacteria) respond to the prevailing physical sediment dynamics by… Expand
Phase E: A high pressure hydrous silicate with unique crystal chemistry
AbstractThe unique cation-disordered crystal structures of two samples of phase E, a non-stoichiometric, hydrous silicate synthesized in a uniaxial, split-sphere, multi-anvil apparatus at conditions… Expand
