At this point we must make a small digression as regards the relevance of the andesite. It is known as a melt rock, produced when ordinary sedimentary rock is melted, usually as the result of volcanic activity. Therefore, it was quite reasonable that the earliest interpretation of the presence of andesite in the Yucatan cores suggested ancient volcanism. But andesite is also produced when the center of an impact crater is melted by the violence of the collision, and the only certain way to tell the two forms apart was to find evidence for shocked quartz.
He recalls that he immediately wrote to Walter Alvarez to suggest that the crater lay in the Yucatan and never heard back. In 1981, aware that the existence of the Yucatan crater had to be announced to a larger audience, he convinced his Mexican colleague and project supervisor, Antonio Camargo, that they should present a report on the crater at a meeting of Society of Exploration Geophysicists in Los Angeles. Camargo agreed and in early October they informed 30 to 35 colleagues of the likely existence of a very large impact crater beneath the Yucatan.
Upon closer study, it turns out that meteorites have killed in recorded history, at least according to Kevin Yau and colleagues at the Jet Propulsion Laboratory in Pasadena, California. C. D. 1920. , in a report attributed to Confucius. A pattern that emerged from the Chinese records was of an excess of falls from 1840 to 1880, which accords with data from European sources. Such an excess is peculiar, because there is no reason to expect the number of meteorites to vary from year to year, given that most of them have been traveling around the sun for millions of years before hitting earth.
