Bright spot
http://dbpedia.org/resource/Bright_spot
In reflection seismology, a bright spot is a local high amplitude seismic attribute anomaly that can indicate the presence of hydrocarbons and is therefore known as a direct hydrocarbon indicator. It is used by geophysicists in hydrocarbon exploration.

地震亮点(英語:bright spot)是指地震波屬性在局部顯示的高振幅异常,一般可指碳氢化合物的存在。起因是含碳氢化合物的砂岩其声阻抗比同層含水的声阻抗低的。如果上層被高声阻抗页岩覆蓋,砂岩頂界反射系数在含碳氢化合物地區會增加。因而造成局部亮點。在深部地層,页岩和砂岩声阻抗会交叉相反,反而造成暗点(dim spot)。
