Alfred Georg Hubertus Fischer (December 12, 1920 – July 2, 2017) was a German-American geologist. Among his influential work was the examination of the climate record over geological time scales and latitudinal gradients in species diversity and numbers across geological time.
[1]: 1 The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, [2] and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. [1]: 1 It is an integrated field of chemistry and geology.
The Goldschmidt classification, [1] [2] developed by Victor Goldschmidt (1888–1947), is a geochemical classification which groups the chemical elements within the Earth according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (sulfide ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in ...
Was there ever a collision of the Earth with another planet Theia, giving birth to the Moon? [1] There is compelling evidence, such as measures of a shorter duration of the Earth's rotation and lunar month in the past, pointing to a Moon much closer to Earth during the early stages of the Solar System. [2] What is the long-term heat balance of ...
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).
Environmental geology – Science of the practical application of geology in environmental problems. Geochemistry – Science that applies chemistry to analyze geological systems; Geologic modelling – Applied science of creating computerized representations of portions of the Earth's crust; Geomorphology – Scientific study of landforms
In Earth science, a geochemical cycle is the pathway that chemical elements undergo to be able to interact with the reservoirs of chemicals in the surface and crust of the Earth. [1] The term " geochemical " tells us that geological and chemical factors are all included.
87 Rb decays in magma and elsewhere so that every 1.42×10 11 years half of the amount has been converted into 87 Sr. Knowing the decay constant and the amount of 87 Rb and 87 Sr in a rock it is possible to calculate the time that the 87 Rb must have needed before the rock reached closure temperature to produce all 87 Sr, yet considering that ...
