WebThe depth of the mid-crustal discontinuity was determined between 10 km to 14 km for the Okavango and Kafue rift zone, which could possibly be the depiction of Conrad discontinuity. Three 2D forward gravity models were generated to compare with the results from the spectral analysis of 2D gravity data. WebSep 1, 2024 · Much weaker than the Moho discontinuity, this discontinuity is not found everywhere, and its existence has long been questioned. However, it was assumed by the middle of the 20th century that the Conrad discontinuity marks the boundary between a granitic upper crust, referred to as SiAl by Eduard Suess (1831–1914) and a more basic, …

WebMar 1, 2024 · The Moho is found at about eight kilometers (five miles) beneath the ocean and about 32 kilometers (20 miles) beneath continents. Different types of rocks distinguish lithospheric crust and mantle. Lithospheric crust is characterized by gneiss ( continental crust) and gabbro ( oceanic crust ). WebMohorovicic Seismic Discontinuity Seismic stations within about 200 km of a continental earthquake (or other seismic disturbance such as a dynamite blast) report travel times that increase in a regular fashion with distance from the source.
WebThe Mohorovicic Discontinuity, commonly called the “Moho” is recognized as the boundary zone between Earth's crust and the mantle. This boundary marks a change in seismic-wave velocity from the crust to the uppermost … WebCalled the Mohorovičić Discontinuity, or Moho for short, this zone was discovered by Andrija Mohorovičić (pronounced mo-ho-ro-vee-cheech; audio pronunciation) in 1909 after studying earthquake wave paths in his native Croatia . The change in wave direction and speed is caused by dramatic chemical differences between the crust and mantle.
