从构造沉降、年轻火山群的存在和高热流的观点来看,俄勒冈Cascades地区具有较高的地热生产潜力。但是,用各种地球物理方法来提供大尺度地壳岩浆体存在的明确证据的努力失败了,这与美国西部某些其它流纹岩火山中心的情况不同。在Hood山和Newberry火山进行的一些远震残差研究没有显示出在这些火山之下存在着可探测到的尺度的地壳岩浆囊 From the point of view of structural subsidence, the presence of young volcanoes and the high heat flux, Cascades, Oregon has a high potential for geothermal production. However, efforts to provide clear evidence of the existence of large-scale crustal magmas with various geophysical methods failed, unlike the situation with some other rhyolite centers in the western United States. Some teleseismic residual studies conducted at Hood and Newberry Volcanoes do not show that there are detectable scales of crustal magma beneath these volcanoes
