					<description><![CDATA[New research shows that fluorine-rich vapor from Finland's Wiborg rapakivi granite melted the Ihalainen marble deposit 1.6 billion years ago, producing an emulsion of silicate and carbonate melts, spectacular spinodal textures, and three potentially new minerals bearing tin, niobium, and tantalum.]]></description>
