Mohorovičić discontinuity
/ˌməʊhəˌrəʊvɪtʃɪtʃ ˌdɪskɒntɪˈnjuːɪti/noun Geology
The boundary surface between the earth’s crust and the mantle, lying at a depth of about 10-12 km under the ocean bed and 40-50 km under the continents.The sharp boundary between the crust and mantle is called the Mohorovicic discontinuity or Moho....
- Wide-angle reflection and refraction seismic data can be used to image the Mohorovicic discontinuity and provide information on the velocity structure and physical properties of the crust.
- These values suggest that the Mohorovicic discontinuity remains relatively deep, 40 to 45 km, beneath western half of the transect.
Origin
1930s: named after Andrija Mohorovičić (1857–1936), Yugoslav seismologist.
