"Red Rock to Red Planet: From Utah Marbles to Mars' Blueberries" The U's Marjorie Chan, Chair and Prof. of Geology and Geophysics will present. The lecture is free and open to the public, and is held in the Aline Wilmot Skaggs Biology Auditorium (just West of the bookstore). Her research on Utah sandstone has yielded clues about the origin of the recently discovered marble-shaped rocks on Mars that are known as hematite concretions and nicknamed "blueberries". Hematite is one of the few minerals found on Mars that forms almost always in water. Hematite concretions require groundwater flow through permeable rock to produce the layered spheres. Moreover, the potential role of bacteria in the formations of some Utah hematitie concretions could hold important clues in the search for life on Mars. Prof. Chan will also give a live radio interview on KCPW 88.3 FM on Tuesday, September 14 from 9:10-9:30 a.m. _______________________________ Do you Yahoo!?
