          HELENA, Mont. (AP) – Scientists using electric and magnetic sensors say they have mapped the size and composition of a vast plume of hot rock and briny fluid hundreds of miles below Yellowstone National Park’s surface.

Study co-author Robert B. Smith of the University of Utah says the so-called “geoelectric” imaging gives researchers a clearer picture of the material that feeds Yellowstone’s volcanic features.

     He says information will help scientists better understand of the evolution of such plumes that are active in 20 places around the world from Hawaii to Iceland.

     The study will be published in Geophysical Research Letters within the next few weeks, according to the American Geophysical Union.
