Physical properties of marine sediments
John E. Nafe,Charles L. Drake +1 more
TL;DR: In this paper, it was shown that seafloor sediments that blanket the ocean floor are of widely varying thickness but seismic observations indicate that 200 to 400 meters in the Pacific and one kilometer in the Atlantic are fairly typical values for deep water.
Journal ArticleDOI
Late Cretaceous and paroxysmal Cretaceous/Tertiary extinctions
TL;DR: In this paper, various geological signatures at Cretaceous/Tertiary time including iridium and other associated elements, microspherules, and shock deformation features are compatible with the suggestion that the transition is marked by a period of intense volcanism.
Journal ArticleDOI
Terminal Cretaceous Environmental Events
TL;DR: The geologic record of terminal Cretaceous environmental events indicates that iridium and other associated elements were not deposited instantaneously but during a time interval spanning some 10,000 to 100,000 years, which favors a mantle rather than meteoritic origin for these elements.
Journal ArticleDOI
The Cretaceous-Tertiary transition
TL;DR: It seems more likely that an explanation for the changes during the Cretaceous-Tertiary transition will come from continued examination of the great variety of terrestrial events that took place at that time, including extensive volcanism, major regression of the sea from the land, geochemical changes, and paleoclimatic and paleoceanographic changes.
Journal ArticleDOI
Crustal structure of the mid‐ocean ridges: 1. Seismic refraction measurements
TL;DR: In this paper, the results of twenty-two seismic refraction stations over the northern mid-Atlantic ridge are combined with earlier data to obtain a better definition of the gross features of the ridge.
