American Antiquity, 1960
AbstractThe immediate stimulus for N. C. Nelson's stratigraphic technique in the Galisteo Basin, New Mexico, was his participation in 1913 in Obermeier and Breuil's excavations in Castillo Cave, one of the most famous of the Spanish paleolithic sites.

Sequence Stratigraphy, Seismic Stratigraphy and Basin Analysis
2010Seismic records are based on measurements of the time sound waves (seismic waves) take to travel through rock. The sound or signal is produced by explosives or compressed air (air guns). Rock is an elastic medium and the velocity of sound conveys a lot of information about the properties of the rock. Normal sound waves (P-waves) travel through both the

Stratigraphy and paleontology in China enjoy the advantage of a solid foundation, particularly that created by the pioneer studies of A. W. Grabau (Zhao, 1961). The two volumes of Grabau’s Stratigraphy of China appeared in 1923–1924 and 1928 respectively.

Historical geology involves concepts of time, life and environments that are unfamiliar to us in terms of personal experience, but it is founded upon the study of materials and of structures that accumulated unevenly across the earth and at greatly varying rates in time.
