Despite considerable progress in seismology, mineral physics, geodynamics, paleomagnetism, and mathematical geophysics, Earth’s inner core structure and evolution remain enigmatic. One of the most significant issues is its thermal history and the curren
Thus, a Space-to-Street-to-Interior-Spaces concept is achieved. In another embodiment, the request for information can be based on viewing contacts by their logical distance. Different pivots on location-context can be utilized, viewing each contact by city, state, or county. When the location...
So I wrote my ten-minute play and sent it off to Carrie. Right before the conference, she wrote to say that she was in the awkward position of turning it down. “I hope you understand why we have to pass on this one this year. I hope you’re still willing to tread the boards wi...
Finally, the interior of the huge mound was built up from local gravel from the banks of the Boyne River. Keep in mind, Newgrange was built before the invention of the wheel made it to Ireland. Archaeologists think that the rocks were carried as far as possible by boat before being ...
WeightlnSLOPE:lnHAND=2:1,Scaleparameter=10,Shapeparameter=0. The unit catchment of MERIT-Basins (Lin et al.2019) and the Noise polygons (2.2.2) were used as thematic layers. Therefore, the uniform slope polygons were divided by the catchment areas as well as by terrain features (Fig.3...
According to the THCO model, an ascending fluid forms a hypogene maze within a soluble rock layer sandwiched between permeable but insoluble rock layers (Fig. 6d). This setting sustains an upward-distributed flow within the soluble strata and precludes the channelized flow that can develop due to...
Present-day magnetic fields of terrestrial planets and moons are either generated in their iron-rich cores (e.g., for the Earth, Mercury, and Ganymede), induced in electrically conducting layers (e.g., in the subsurface oceans of icy satellites), or are due to remanently magnetized crustal...
More than one teramole of carbon per year is subducted as carbonate or carbonaceous material. However, the influence of carbonation/decarbonation reactions on seismic activity within subduction zones is poorly understood. Here we present field and micros
A simplified graphic of the inner Earth as described by the new research. The white and black layers represent a slurry layer containing iron crystals. The iron crystals form in the slurry layer of the outer core (white). These crystals 'snow' down to the inner core, where they accumulate...
