Prior to 1965 geologists assumed that the two giant rock plates meeting at the San Andreas Fault generate heat through friction as they grind past each other, but in 1965 Henry found that temperatures in drill holes near the fault were not as elevated as had been expected. Some geologists wondered whether the absence of friction-generated heat could be explained by the kinds of rock composing the fault. Geologists’ pre-1965 assumptions concerning heat generated in the fault were based on calculations about common varieties of rocks, such as limestone and granite; but “weaker” materials, such as clays, had already been identified in samples retrieved from the fault zone. Under normal conditions, rocks composed of clay produce far less friction than do other rock types. In 1992 Byerlee tested whether these materials would produce friction 10 to 15 kilometers below the Earth’s surface. Byerlee found that when clay samples were subjected to the thousands of atmospheres of pressure they would encounter deep inside the Earth, they produced as much friction as was produced by other rock types. The harder rocks push against each other, the hotter they become; in other words, pressure itself, not only the rocks’ properties, affects frictional heating. Geologists therefore wondered whether the friction between the plates was being reduced by pockets of pressurized water within the fault that push the plates away from each other.

The passage mostly agree that Henry’s findings about temperature in the San Andreas Fault made the greatest contribution in that they

题目问的是henry 发现的贡献,henry的发现是SAF断层处的温度没有想象的那么高,而这个是和之前地理学家长期相信的是不符的,是个意外的发现。
选项A revealed an error in previous measurements未提及
选项B indicated the types of clay present与文章内容不符,如果是这种贡献,那么henry需要发现SAF的岩石组成应该是怎么样的
选项C superiority of a particular technique 与文章内容不符,如果是这个答案,那么henry是用来一种什么technique温度测得特别准,之前的都算错了。
选项D 正确
选项E confirmed geologists’ assumptions 与文章内容不符,henry的发现与之前的地理学家的观点是相悖的
