He insisted that the iridium had been deposited by volcanic action even while conceding in a newspaper interview that he had no actual evidence of it. As late as 1988 more than half of all American paleontologists contacted in a survey continued to believe that the extinction of the dinosaurs was in no way related to an asteroid or cometary impact.
他堅(jiān)持認(rèn)為，銥是由火山活動(dòng)沉積的，即使他在一次記者采訪中承認(rèn)，他拿不出真憑實(shí)據(jù)。直到1988年，在接受一次調(diào)查的美國古生物學(xué)家當(dāng)中，半數(shù)以上依然認(rèn)為恐龍的滅絕跟小行星或彗星撞擊毫無關(guān)系。
The one thing that would most obviously support the Alvarezes' theory was the one thing they didn't have—an impact site. Enter Eugene Shoemaker. Shoemaker had an Iowa connection—his daughter-in-law taught at the University of Iowa—and he was familiar with the Manson crater from his own studies. Thanks to him, all eyes now turned to Iowa.
有一樣最明顯地可以支持阿爾瓦雷斯父子理論的東西，正是反對(duì)者們?nèi)鄙俚囊粯訓(xùn)|西──一個(gè)撞擊現(xiàn)場(chǎng)。尤金·蘇梅克出場(chǎng)了。蘇梅克在艾奧瓦有個(gè)關(guān)系──他的兒媳在艾奧瓦大學(xué)任教──他通過自己的研究很熟悉曼森大坑。多虧了他，大家的目光現(xiàn)在轉(zhuǎn)向艾奧瓦。
Geology is a profession that varies from place to place. In Iowa, a state that is flat and stratigraphically uneventful, it tends to be comparatively serene. There are no Alpine peaks or grinding glaciers, no great deposits of oil or precious metals, not a hint of a pyroclastic flow. If you are a geologist employed by the state of Iowa, a big part of the work you do is to evaluate Manure Management Plans, which all the state's "animal confinement operators"— hog farmers to the rest of us—are required to file periodically. There are fifteen million hogs in Iowa, so a lot of manure to manage.
地質(zhì)學(xué)這個(gè)職業(yè)各地不一樣。艾奧瓦是個(gè)地勢(shì)平坦、地層毫無特色的州。因此，相對(duì)而言，艾奧瓦的地質(zhì)工作往往風(fēng)平浪靜。這里沒有高聳的山峰或滑動(dòng)的冰河，沒有石油或貴重金屬的大量?jī)?chǔ)備，沒有巖漿奔流的跡象。如果你是艾奧瓦州聘用的一名地質(zhì)學(xué)家，你的大部分工作是評(píng)估全州的“幽禁動(dòng)物工作者”──即豬場(chǎng)主──被要求定期提供的“肥料管理計(jì)劃”。艾奧瓦州養(yǎng)了1500萬頭豬，因此有大量的肥料需要管理。
