      Attempts to use carbonate units as stratigraphic markers have been counfounded by inconsistent identification of ‘cap carbonates’ and a somewhat broad use of the term. Systematic sedimentological and geochemical analysis of carbonate rocks (mostly dolomite) associated with glacigenic deposits from the Neoproterozoic succession of the Cited by: The ‘Great Unconformity’ and associated geochemical evidence for Noahic Flood erosion Harry Dickens T he Bible’s Flood account describes the greatest rain event ever recorded. Forty days and nights of rain falling on the earth (Genesis ) would have caused immense denud­ ation of landmasses around the globe.   Searching for sudden events that might explain the disappearance of sizeable proportions of fossil taxa is a growing cottage industry among geologists. Until , with Alvarez’ discovery of geochemical evidence for a comet or asteroid impact at the Cretaceous-Tertiary boundary, such tumbles in life’s diversity and volume were merely palaeontological markers which geologists . The Phanerozoic paleotemperature maps from PALEOCLIMATE contain surface temperature superimposed on paleogeographic templates (elevated areas, land masses, shallow and deep sea patterns). The paleotemperature map can be used as input for geochemical modeling software like COMPAS and for basin maturation evaluations.

Syktus. Phanerozoic Eon, the span of geologic time extending about million years from the end of the Proterozoic Eon (which began about billion years ago) to the present. The Phanerozoic, the eon of visible life, is divided into three major spans of time largely on the basis of characteristic assemblages of life-forms: the Paleozoic ( million to million years ago), Mesozoic ( million.

The Age of Ancient Life. Of the three main eras that make up the Phanerozoic, the Paleozoic is the longest and most diverse, spanning the period from very early multicellular life that only inhabited the oceans to quite advanced tetrapods* and reptiles and extensive forests.

The Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers million years to the present, and began with the Cambrian Period when animals first developed hard shells preserved in the fossil record.

Our perspective on biological evolution is that it is a cosmic phenomenon, born of galactic and solar-system processes and influencing the further development of planetary surfaces where it occurs.

Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era.

Geochemical arguments suggest that phosphorus is the culprit. The weathering of apatite, the primary phosphorus sink in Earth's exosphere, controls long-term phosphorus availability.

Evidence for climate changes, such as biological indicators, geochemical parameters, and the presence of ice, are compared between these modes.
