A portrait of Whiston with a diagram demonstrating his theories of cometary catastrophism best described in A New Theory of the Earth. It was not until the 17th century that geology made great strides in its development. At this time, geology became its own entity in the world of natural science.
1960 – Harry Hess proposes that new sea floor might be created at mid-ocean rifts and destroyed at deep sea trenches 1963 – Frederick Vine and Drummond Matthews explain the stripes of magnetized rocks with alternating magnetic polarities running parallel to mid-ocean ridges as due to sea floor spreading and the periodic geomagnetic field ...
The 79 new giant oil and gas fields discovered from 2000–07 tended to be located in similar tectonic settings as the previously documented giants from 1868–2000, with 36 percent along passive margins, 30 percent in rift zones or overlying sags (structures associated with rifts), and 20 percent in collisional zones.
Note: René Haüy discovered that emeralds and beryls crystals are geometrically identical. He asked Vauquelin for a chemical analysis, and so Vauquelin found a new "earth" (beryllium oxide). Carl Wilhelm Scheele (1742 –1786), discovery of oxygen with Priestley; identification of molybdenum, tungsten, barium, hydrogen, and chlorine.
The fossils were discovered from the Vindhyan Mountains in Central India by Rafat Jamal Azmi at the Wadia Institute of Himalayan Geology, Dehradun, who reported in the Journal of the Geological Society of India in 1998. [100] Azmi announced the discovery in Science [101] and was immediately received with
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

The 17,500-square-foot (1,630 m 2) pavilion lets visitors observe as paleontologists carry out excavations of new discoveries exactly where the fossilized remains lie preserved. [10] Specially constructed walkways afford visitors an unobstructed close-up view of paleontologists at work during the summer field season.
The survey data was large step towards many more discoveries about the geology of the sea. [6] A theoretical model of the formation of magnetic striping. New oceanic crust forming continuously at the crest of the mid-ocean ridge cools and becomes increasingly older as it moves away from the ridge crest with seafloor spreading.
