What did Abraham Gottlob Werner discover?

Abraham Gottlob Werner, (born Sept. 25, 1750, Wehrau, Saxony—died June 30, 1817, Freiberg), German geologist who founded the Neptunist school, which proclaimed the aqueous origin of all rocks, in opposition to the Plutonists, or Vulcanists, who argued that granite and many other rocks were of igneous origin.

What does a Disconformity in a sedimentary rock sequence represent?

A disconformity is an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition. This type of erosion can leave channels and paleosols in the rock record.

Who is the father of Uniformitarianism?

James Hutton. Along with Charles Lyell, James Hutton developed the concept of uniformitarianism. He believed Earth’s landscapes like mountains and oceans formed over long period of time through gradual processes.

What was Alfred Wegener claim?

Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

When did Wegener make his discovery?

Wegener first presented his theory in lectures in 1912 and published it in full in 1915 in his most important work, Die Entstehung der Kontinente und Ozeane (The Origin of Continents and Oceans).

Who discovered stratum?

Smith noticed that two beds of rock might contain several identical fossil species, but one or two species would vary. These subtle differences between fossil groups, or assemblages, enabled Smith to differentiate rock strata that appeared otherwise identical.

What was William Smith famous for?

William ‘Strata’ Smith (23 March 1769 – 28 August 1839) was an English geologist, credited with creating the first detailed, nationwide geological map of any country.

What is Disconformity and nonconformity?

A nonconformity is what its called when sedimentary rock strata are over crystalline (metamorphic or igneous) strata. A disconformity is when the sedimentary strata is over another sedimentary strata.
