... within mining blasts are simulated for observed explosions from the Mesabi Range in Minnesota and for a series of quarry blasts at the Kaiser Permanente Quarry in Cupertino, California, which included a simultaneous detonation conducted by Lee et al. (1989). The Mesabi explosions are examples of large...

...V. Courtillot; H. Feinberg; J. P. Ragaru; R. Kerguelen; M. McWilliams; A. Cox Abstract Limestone and diabase from 11 sites in the Permanente Quarry, the largest outcrop of Calera limestone in the Franciscan terranes, have been studied by paleomagnetic and biostratigraphic methods. Observation...

...) in a high-resolution biostratigraphy utilizing planktic foraminifers studied in thin section. A section, about 110 m-thick, was measured from the middle thrust slice exposed by quarrying on the southwest side of Calera Hill at Pacifica Quarry. Lithologically, the section is divided in two units; a lower...

...Ian C. F. Stewart Abstract Teleseisms and quarry blasts were recorded at 24 temporary seismograph sites along a line across the northern Dunnage Zone of Newfoundland. Azimuthally dependent functions were also determined for teleseismic P -wave travel-time residuals at the permanent St. John's (STJ...

Identical foraminiferal assemblages of Turonian age have also...

Our own field reconnaissance indicates that faults in eastern El Salvador consist dominantly of N-striking, normal faults, in accord with our DEM analysis. Normal faults were observed throughout the region in well-exposed, albeit rare, quarries...

This was named Australopithecus africanus (‘the Man-Ape of South Africa’) and marked transitional “missing link” in hominid evolution, which would...
