The Kechika Trough in the Rocky Mountains of northern British Columbia is host to numerous sedimentary exhalative barite-lead-zinc deposits collectively known as the Gataga mineral district. This report summarizes the bedrock mapping component of a multi-disciplinary study of the northern part of this basin. Field data for this component were collected during the summers of 1994 to 1996. Sections of the report describe the study area's lithologic units (Proterozoic to Cambrian strata, intrusives), geologic structure (faults, folds, cleavage), metamorphism, and economic geology (mineralization, skarns, veins, sulphides).

In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide. This Memoir consists of a series of overview chapters followed by site-specific chapters. The overviews cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic & geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.

The 20 chapters of The Geology of Washington and Beyond�an outgrowth of a geologic symposium�present the substantial advances in recent research on the geologic history of Washington State. The 32 contributors used new conceptual developments such as sequence stratigraphy, identification and matching of terranes, and neotechtonics, as well as breakthroughs in technology such as lidar mapping, paleomagnetism, and new methods of radiometric dating, to examine the fascinating geology of Washington State and beyond. Also included is geologic mapping in areas previously known only by reconnaissance. This book will influence resource management decisions, as well as disaster and land-use planning in the region. The introductory chapters make the book accessible for undergraduate courses in geology and to the general public.

"In this well-illustrated book, Hildebrand expands upon his model for the development of the North American Cordillera detailed in Special paper 457. Starting with an overview of Cordilleran geology he goes on to provide an in depth look at how the Rubian ribbon continent was assembled. He integrates the complex geology of the Cordillera into an actualistic model involving arc magmatism, arc-continent collision, slab failure magmatism, and transcurrent motion in both Rubia and the western North American margin. While much of the focus is on the assembly of the Rubian ribbon continent, Hildebrand explores its interactions with North America during the Sevier and Laramide events and concludes that North America was the lower plate in both"--Provided by publisher.
