The 3.43 billion-year-old Strelley Pool Chert, Pilbara Craton, Western Australia, contains compelling evidence of Early Archaean life in the form of kilometre-sized remnants of an ancient stromatolitic carbonate platform. Reviewing and building on earlier studies, we examine the fossilized remains of the platform to seek ecosystem-scale insights to Earth’s early biosphere, examining the evidenc...
Field and laboratory observations indicate that the frictional behaviors of faults depend on hydrothermal conditions. We extend microphysical Chen-Niemeijer-Spiers (CNS) model to conditions by using observed temperature variation indentation hardness infer dependence a parameter . This is assumed constant in previous versions CNS model. A simple spring-slider system used simulate fault investig...
The utilization of renewable energy resources is desirable owing to several issues, including the depletion of petroleum resources and global warming1). Among many kinds of renewable resources, marine biomass (macroalgae) could be a promising feedstock for bioproduct and biofuel production2),3). However, appropriate pretreatment is needed prior to its effective utilization. Owing to the high wa...
