Anisotropic poroelasticity and the response of faulted rock to changes in pore-fluid pressure. In D. Healy, R. W. H. Butler, Z. K. Shipton, R. H. Sibson (Eds.), Faulting, Fracturing and Igneous Intrusion in the Earth's Crust(vol. 367, 201-214). Geological Society of London, ...
Focusing on the hydrosphere, it encompasses all of Earth’s water, which is crucial for life. This sphere includes surface water, such as rivers, lakes, and oceans; groundwater that saturates the soil and rock beneath our feet; ice and snow found in polar regions and mountain peaks; and w...
Kids can learn with every delicious bite of this Layers of the Earth Pudding Cup. These dinosaur topped treats make fun party desserts too.
Earth's auroras are a glorious wonder, but our planet isn't the only place in the Solar System where these phenomena can be found. An atmospheric glow, albeit sometimes in invisible wavelengths, has been spotted at every planet except Mercury, and even some moons of Jupiter ... and even ...
Sapphires form inside the fiery hearts of volcanoes, not deep in the mantle like we thought Live Science - August 6, 2024 A new study of sapphires found in volcanic fields in Germany reveals that these beautiful blue stones form where magma and rocks from Earth's crust mix. ...
Earth’s crust contains a substantial proportion of global biomass, hosting microbial life up to several kilometers depth. Yet, knowledge of the evolution and extent of life in this environment remains elusive and patchy. Here we present isotopic, molecular and morphological signatures for deep ancie...
As we step into the ancient Earth, we lose the ability to measure fluids directly, yet the fluid envelope remained a key component of the Fe biogeochemical cycle in Earth’s past, especially in an anoxic Earth when large quantities of Feaq2+ existed in the oceans....
We applied conventional thermobarometry and forward thermodynamic modelling to constrain the P–T evolution ranging from the peak metamorphic conditions of the investigated harzburgite and lherzolite, through entrapment of the melts in the outer parts of garnets, to the (re)-equilibration of the MSI...
In the Middle Proterozoic the Baltic shield formed part of a suggested Nuna supercontinent (a.k.a Columbia) (e.g., Elming et al., 2021). The assembly and break-up of Nuna may be considered the Earth’s first supercontinent cycle (e.g., Worsley et al., 1984, Nance et al., 1986,...
This natural substance with a somewhat unwieldy name is made from a sedimentary rock created by fossilized algae (diatoms), and which is a rather abundant resource (diatomaceous earth is said to make up 26 percent of the earth's crust by weight).4 ...
