Study of the velocity conditions in the earth's crust in the regions of the Bohemian massif and the carpathian system along international profiles VI and VII

Shear wave crustal velocity model of the Western Bohemian Massif from Love wave phase velocity dispersion

“…For example partial melting would affect v s more seriously than the v p . Beránek (1971) found the LVZ in the v p distribution using reflection for Moldanubian and Teplá-Barrandian units. Since we have found the LVZ for the same two units for v s as well, we think that our results may be realistic in this respect.…”

“…In the 1960s, an international deep seismic sounding profile was shot across the southwestern Bohemian Massif. Data were interpreted by Beránek (1971) and Beránek et al (1973). Beránek (1971) gave an indication of lower velocities in the upper and middle crust for the Teplá-Barrandian and Moldanubian unitshe interpreted it as evidence of their sedimentary composition and pointed out the fact that we can find low velocities down to the depths of 20 km although these units are so old.…”

Beránek and Zounková (1977) complemented the results from the deep seismic sounding profile by measurements of Pwave velocities from quarry blasts round the whole Czech Republic.…”

Vertically Inhomogeneous Models of the Upper Crustal Structure in the West-Bohemian Seismoactive Region Inferred from the Celebration 2000 Refraction Data

“…In the Czech Republic, the first deep seismic soundings (DSS) were carried out along two international profiles between 1964−1972 using borehole shots (Beránek, 1971). Various details of this research have been described in several review articles (Novotný and Urban, 1988;Mayerová et al, 1994).…”

Ultrasonic velocity of the upper gneiss series rocks from the Outokumpu deep drill hole, Fennoscandian shield — Comparing uniaxial to triaxial loading

“…The depth determination of the seismic reflectors depends on the accuracy with which the velocity data in the crust is known (Beránek and Tobyáš, 1971). To improve our understanding of crustal structures (Elbra et al, submitted for publication) and geological evolution (Pesonen et al, 2008) of the Outokumpu area in eastern Finland (Fennoscandian shield), and in particular the Outokumpu deep drilling site, we need seismic velocities (Vp and Vs) as a function of depth.…”
