Caeculus IV opens with a dedication to professor Marianne Kleibrink on the occasion of her 60th birthday, followed by a complete list of her publications. The Proceedings of the 4th Fransum Colloquium start with an article of Christopher Smith, entitled "Ritualising the Economy". He presents a theoretical base for a correlation between ritual and economy. Smith outlines some recent theories which incorporate economic activity into ritual context, actions into thought or, as one could say, matter into mind. Furthermore, he tries to relate this theoretical framework to the archaeological evidence from Latium Vetus, the region on which his own research focuses. The results from the recent Dutch excavations in Italy at Satricum seem to correspond fairly well with the discussed theories. His paper offers, therefor, a suitable foundation for the following contributions, most of which concentrate on central Italy. The second contribution by Tsjeard Hoekstra deals with the biography of bronze hoards from Italy. Albert Nijboer continues the debate with a discussion of the significant changes in hoarding in central Italy from 800 to 500 BC. The fourth paper by Demetrius Waarsenburg and Hendrieneke Maas deals with the bronzes deposited in the early sanctuary at Satricum in Lazio. Jelle Bouma discusses the same shrine as the previous authors but during the subsequent period, the 5th and 4t centuries BC. He presents a report of his excavation of the second votive deposit at the main shrine of Satricum. Peter Attema presents in his paper evidence of a recent survey in the area around Sezze, ancient Setia. The paper by Marjan Galestin discusses Roman coin hoards in the Netherlands. The last paper, not related to the central topic of this issue, is by Patricia Roncoroni who studies children's graves in Latium during the early Iron Age.

Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.

The aim of this publication is the understanding of large floods and their impact on the Earth's surface. The major objectives are: 1) to take a second look at what constitutes a megaflood that the principle of uniformitarianism is at some loss to explain and 2) to try to determine what could happen in such large floods by analyzing those that occur in front of glaciers, in alluvial-fans and in alluvial valleys. The products of these floods are presented in terms of sedimentary deposits, erosional features and damage to human activities. The volume bears out the concept that sedimentological analysis can be a powerful tool, not only for reconstructing processes that have acted on ancient landscapes, but also as a technique for risk assessment of certain troubled areas. Therefore, this volume is of interest not only to sedimentologists/gemorphlogists, but also to engineers, landuse planners and anyone interested in the interrelation between humans and the environment.

The Joint 6th Biennial SGA-SEG Meeting was held in Krakow in August 2001. This volume contains 274 extended abstracts, grouped thematically under 18 session titles covering topics such as lead-zinc deposits; metamorphism affecting mineral deposits; and the environmental aspects of mining.

The latest knowledge on mineral ore genesis and the exploration of ore deposits Global demand for metals has risen considerably over the past decade. Geologists are developing new approaches for studying ore deposits and discovering new sources. Ore Deposits: Origin, Exploration, and Exploitation is a compilation of diverse case studies on new prospects in ore deposit geology including atypical examples of mineral deposits and new methods for ore exploration. Volume highlights include: Presentation of the latest research on a range of ore deposit types Application of ore deposits to multiple areas of geology and geophysical exploration Emphasis on diverse methods and tools for the study of ore deposits Useful case studies for geologists in both academia and industry Ore Deposits: Origin, Exploration, and Exploitation is a valuable resource for economic geologists, mineralogists, petrologists, geochemists, mining engineers, research professionals, and advanced students in relevant areas of academic study.
