The Chalice gold deposit (~ 20 t Au produced), in the southwestern portion of the Late-Archean Norseman-Wiluna greenstone belt of the Yilgarn Craton, Western Australia, is hosted both in a sequence of intercalated mafic and ultramafic amphibolites and a post-peak metamorphism monzogranite dike. The deposit is flanked on the western side by calc-alkaline plutonic rocks, and to the east by a predominantly monzogranitic pluton, with at least four generations of monzogranitic dikes that intrude the local mine stratigraphy. Locally, four deformation events (D1–D4) have affected this sequence of amphibolites, and two stages of gold mineralisation are recognised, controlled by the progressive D2 event.

Planetary scientist and educator Ken Coles has teamed up with Ken Tanaka from the United States Geological Survey’s Astrogeology team and Phil Christensen, Principal Investigator of the Mars Odyssey orbiter’s THEMIS science team, to produce this all-purpose reference atlas, The Atlas of Mars. Each of the 30 standard charts includes: a full-page color topographic map at 1:10,000,000 scale, a THEMIS daytime infrared map at the same scale with features labeled, a simplified geologic map of the corresponding area, and a section describing prominent features of interest. The Atlas is rounded out with extensive material on Mars’ global characteristics, regional geography and geology, a Glossary of Terms, and an indexed Gazetteer of up-to-date Martian feature names and nomenclature. This is an essential guide for a broad readership of academics, students, amateur astronomers, and space enthusiasts, replacing the NASA atlas from the 1970s. <...>

In 1997 the British Columbia Geological Survey (BCGS) initiated a project to identify prospective areas for sediment-hosted gold mineralization. The inspiration for the project came from presentations and articles by Howard Poulsen of the Geological Survey of Canada (1996a, 1996b). He pointed out that there is potential to find hypogene, sediment-hosted gold mineralization in Canada akin to deposits found in Nevada. He mentioned that if an intrusive association is important to generate the mineralization, then two different geological environments might host this style of mineralization. Accreted terranes with a basement containing carbonate lithologies intruded by Mesozoic or Cenozic plutonism would be a prospective geological setting, specifically the Stikine and Quesnel terranes. The second favourable environment is within the sediments deposited along the continental margin of ancestral North America which have been cut by Mesozoic magmas, such as are found in the Kootenay Arc and Selwyn Basin (Figure 1).

Others have considered British Columbia as prospective territory for sediment-hosted gold. Early work by companies focused on the Insular Belt rocks exposed on Vancouver Island and the Queen Charlottes. These exploration programs were based largely on an epithermal-style model for the mineralization which was in favour at the time. The discovery of the Babe deposit (now called the Specogna or Cinola) in the Queen Charlotte Islands in 1970 increased the interest in this model because it was initially identified as a Carlin-type deposit (Richards et al, 1976; Champigny  and Sinclair,   1982). <...>

Part 2 includes descriptions of 13 species belonging to 5 genera (including Simpsonibelus gen. nov. and Brevibelus nom. nov.) of the Belemnitidae d'Orbigny; 3 species belonging to one genus of the Salpingoteuthididae fam. nov.; and one species belonging to one genus of the Belemnoteuthididae Zittel.
