Book Description
Modern civilizations dependence upon an increasing volume and diversity of minerals makes the search for new ore deposits ever more difficult. Now available from Waveland Press, Guilbert & Parks text presents ideas, principles, and data fundamental for beginning economic geologists to understand the genesis and localization of ore deposits and of the minerals associated with them. The authors comprehensively describe the physical and chemical characteristics of ore deposits and correlate them with environments and conditions of deposition, since ore deposits are best interpreted as extensions of the environments responsible for their enclosing rocks. Examples and illustrations emphasize structural, chemical, and temporal controls and encourage the three-dimensional thinking used by productive explorationists as they face unsolved problems. This upper-level undergraduate text is fully illustrated and meticulously indexed. Its reliable, authoritative coverage assumes an upper-level command of chemistry and physics, as well as mineralogy, petrology, and structural geology. Outstanding features . . . develops and combines the abilities of the explorationist and of the researcher of ore-forming processes structures the geologic descriptions into groupings recognized by researchers and explorers alike builds confidence, revitalizes curiosity, and encourages expanded thinking emphasizes that the days of easy discovery of outcropping ores are not over includes revised, expanded, and updated descriptions of districts

Book Description
This volume is based on the recognition that heritage is popular and popular culture is now readily transformed into heritage, whose meanings and myths reshape social life and political and economic realities, as well as re-make "tradition". The papers in this volume consider: What does popular heritage look like? To whom does it speak? Is it active in dissolving class and cultural boundaries or just in reproducing new ones? How do societies manage a heritage that is fluid, immediate and that straddles extremes of serious conflict and hedonistic frivolity? When and under what circumstances is the creation and expression of new cultural forms - popular culture - capable of being transformed into heritage?
