The papers included in this volume were originally presented orally or as posters at the Society of Economic Geologists International Field Conference on Carbonate-Hosted Lead-Zinc Deposits, held in St. Louis, Missouri, June 3-6, 1995. The concept for this conference was first aired at the conclusion of an SEG field trip to the East Tennessee MVT district in October, 1992. Response was both instantaneous and extraordinarily positive; several participants came forward immediately and volunteered to help organize either the conference or the fie ld trips. At almost the same time, and quite fortuitously, SEG received offers from Australia and Ireland to organize field trips to carbonate-hosted lead-zinc deposits in those countries. As the expression goes, it didn't take a rocket scientist to suggest that all three proposals be combined into a single mega-event. And so it came about that, in less than three years and in celebration of its 75th Anniversary, SEG organized a six-week field conference in 1995 beginning May 13-19 in Ireland, then reconvening June 3-6 in StLouis, MO, and again in Australia June 15-23. Although the Australian portion had to be cancelled, field guidebooks were successfully published for all three venues.Fifty-eight manuscripts were submitted and, after passing two peer reviews, fifty were accepted for publication. Papers are presented in groups ranging from district and thematic overviews to specialized research topics. An extra effort was made to include carbonate-hosted deposits other than the obvious Mississippi Valley-type and, to this end, we can claim moderate success.The Editor and Editorial Board of this volume owe a debt of gratitude to the many people who helped produce it in a timely fashion. We include here those authors who turned in their manuscripts at the StLouis meeting (thereby permitting the review process to begin almost immediately), the nearly 100 reviewers who conscientiously responded to our requests for a rapid "turn around" of their reviews, and, finally, the authors themselves for their diligence in maintaining the momentum, for heeding our page limitations, and, because of the requirements for camera-ready copy, accepted the Editor's requests to reduce their diagrams and photos to our specifications before submitting final copy of their manuscript.The Editor reserves special thanks to his Editorial Board members on whom fell the thankless job of finding reviewers and prodding authors to make revisions and return the finished product; to Ray Coveney, Chairman of the SEG Publications Committee, who provided wise

Exhumation rates and long-term landscape evolution, Northwest Namibia

EGUGA (2012)

Markus Karl Melissa Perner Ulrich A. Glasmacher Peter Christian Hackspacher G. Schneider

The aim of this project is the quantification of the cooling, exhumation, rock and surface uplift, and long-term dynamic topography evolution of the South Atlantic passive continental margin (SAPCM) in Namibia. Excellent onshore outcrop conditions and complete rift to post-rift archives Namibia (onshore Walvis ridge) allow a high precision quantification of long-term processes and process-response systems. This climate-continental margin-mantle coupled process-response system is caused by the interaction between endogenic and exogenic forces, which is related to the mantle-process driven rift ‐ drift ‐ “passive” continental margin evolution of the South Atlantic, and the climate change since the Early/Late Cretaceous climate maximum. Special emphasis will be given to the influence of long-living transform faults such as the Omaruru Lineament, the Waterberg Thrust, and the Okahanja Lineament running perpendicular in the continent and the coast parallel Sesfontein and Puros Shearzone in the Kaokoveld on the long-term dynamic topography evolution of the SAPCM’s. A combination of apatite and zircon fission-track and (U-Th-Sm)/He thermochronological data with modeling of t-T path 0 s will determine cooling, exhumation, and rock and uplift rates thru time. Additionally, already published thermochronological data will be integrated. Sampling strategy considered the recent morphology of the landscape, known fracture and fault zones, and variations in lithologies. Furthermore, sampling at the surface followed the outline of the seismic lines shot by the GFZ Potsdam. Altogether 140 samples were collected in two field campaigns between Angola in the North and Walvis Bay in the South. Special emphasis was given to the Kaokoveld area in the far NW of Namibia. The field work included a description of lithology and quantification of structures of all sample outcrops.
