When these tracers are considered separately, simple scenarios of changes in geochemical and geological factors can be used to explain the historical records. These factors include: (1) increases in continental

However simple this geological product may be, it needs just as much attention, for almost each application, as arrow heads needed in prehistoric time. Bill Langer (USGS) stated in this respect at the Aggregate 2001 conference (Helsinki): “nothing is as simple as it seems, and certainly ...
Obviously, Mitchell’s figure is schematic and not intended to be interpreted too literally. For example, if we could compute the Fourier transform of temperature records available over the entire geological history, the spectral line of the diurnal cycle would be broadened due to the tidally-force...
The above-mentioned approaches, in regards to HC migration, have been developed because Darcy flow models often being too complex to be computed within an acceptable time frame. Even considering small geological deposits, computational time frequently appears too high and, thus, unreasonable. Map-base...

Getty Homo sapiensnow rivals the great forces of nature. Humanity is a prime driver of change of the Earth system. Industrialised societies alter the planet on a scale equivalent to an asteroid impact. This is howthe Anthropocene– the proposed new geological period in which human activity pr...

Photo: Warming Island: These photos taken from the USGS Landsat satellite in 1985, 2002, and 2005 show how a new island has appeared in Greenland following the melting of an arctic glacier. Melting glaciers are one indication that the world is warming up. Picture courtesy ofUS Geological Surv...
