GEOLOGY OF THE MOUNT BRUSSILOF MAGNESITE DEPOSIT, SOUTHEASTERN BRITISH COLUMBIA (825/12, 13) By George J. Simandl and Kirk D. Hancock KEYWOKLIS: Industrial minerals, rconomic geology. mag- nesitr. Cathedral Formation. Middle Cambrian. dolumitiz- tion, porosity. base metal association, deposit model. INTRODUCTION Magnesite (M&O,) is an induswial mineral that can bc converted into either caustic, fused or dead-burned magne- sia. Dead-burned magnesia is used mainly in the manufac- ture of refractory products; caustic magnesia is used in treatment of water, in animal feedstuffs, fertilizers. magne- sia cements, insulating boards and wood-pulp processing, in chemicals and pharmaceuticals and us a curing agent in rubber (Coope. 19X7). Magnesium metal is produced either from magnesite or from caustic mapnesia. In the short-term future. production of dead-burned mag- nesia is cxpectcd to remain constant. however, demand for caustic magnesia is increasing (Duncan, IYYO). With the increasing trend toward the use of high-perfomxmce “mag- carbon” refractories. future demand for fused magnesia looks promising. A number of magnesite deposits are known in British Columbia (Grzant, 19X7). the most important of these is the Mount Brussilof orebody. It is hosted by dolomites of the TECTONIC SETTING Middle Cambrian Cathedral Formation. The Mount Brussilof deposit is located in the Forekm3 rectonostratiEnlphic belt and within the “Kicking Horse HISTORY Rim”, as defined by Aitken (1971, 1989). It is situated east of a Cambrian bathymetric feature commonly referred to as The Mount Brussilof deposit was discovered during the Cathedral escarpment (Fritz. 1990: Aitken xnd regional mapping by the Geological Survey of Canada Mcllreath, 19X4, 1990). -

It preserves a diverse, exceptionally preserved fauna that inhabited a relatively deep water environment at the offshore margin of a carbonate platform, resembling the setting of the underlying Wheeler and Marjum formations. However, the Weeks fauna differs significantly in composition from the other remarkable biotas of the Cambrian Series 3 of Utah, suggesting a significant Guzhangian faunal restructuring. -

The Early History of the Metazoa—A Paleontologist's Viewpoint

Zhuravlev Geological Institute, Russian Academy of Sciences, per. Pyzhevsky 7, Moscow, 7119017 Russia email: [email protected] Received January 21, 2014 Abstract—Successful molecular biology, which led to the revision of fundamental views on the relationships and evolutionary pathways of major groups (“phyla”) of multicellular animals, has been much more appre ciated by paleontologists than by zoologists. This is not surprising, because it is the fossil record that provides evidence for the hypotheses of molecular biology. The fossil record suggests that the different “phyla” now united in the Ecdysozoa, which comprises arthropods, onychophorans, tardigrades, priapulids, and nemato morphs, include a number of transitional forms that became extinct in the early Palaeozoic. The morphology of these organisms agrees entirely with that of the hypothetical ancestral forms reconstructed based on onto genetic studies. No intermediates, even tentative ones, between arthropods and annelids are found in the fos sil record. The study of the earliest Deuterostomia, the only branch of the Bilateria agreed on by all biological disciplines, gives insight into their early evolutionary history, suggesting the existence of motile bilaterally symmetrical forms at the dawn of chordates, hemichordates, and echinoderms. Interpretation of the early history of the Lophotrochozoa is even more difficult because, in contrast to other bilaterians, their oldest fos sils are preserved only as mineralized skeletons. -

A New Phyllopod Bed-Like Assemblage from the Burgess Shale of the Canadian Rockies
ARTICLE Received 30 Dec 2013 | Accepted 7 Jan 2014 | Published 11 Feb 2014 DOI: 10.1038/ncomms4210 A new phyllopod bed-like assemblage from the Burgess Shale of the Canadian Rockies Jean-Bernard Caron1,2,3, Robert R. Gaines4,Ce´dric Aria1,2, M. Gabriela Ma´ngano5 & Michael Streng6 Burgess Shale-type fossil assemblages provide the best evidence of the ‘Cambrian explosion’. Here we report the discovery of an extraordinary new soft-bodied fauna from the Burgess Shale. Despite its proximity (ca. 40 km) to Walcott’s original locality, the Marble Canyon fossil assemblage is distinct, and offers new insights into the initial diversification of metazoans, their early morphological disparity, and the geographic ranges and longevity of many Cambrian taxa. The arthropod-dominated assemblage is remarkable for its high density and diversity of soft-bodied fossils, as well as for its large proportion of new species (22% of total diversity) and for the preservation of hitherto unreported anatomical features, including in the chordate Metaspriggina and the arthropod Mollisonia. The presence of the stem arthropods Misszhouia and Primicaris, previously known only from the early Cambrian of China, suggests that the palaeogeographic ranges and longevity of Burgess Shale taxa may be underestimated. 1 Department of Natural History-Palaeobiology, Royal Ontario Museum, 100 Queen’s Park, Toronto, Ontario, Canada M5S 2C6. 2 Department of Ecology and Evolutionary Biology, University of Toronto, 25 Willcocks Street, Toronto, Ontario, Canada M5S 3B2. 3 Department of Earth Sciences, University of Toronto, 25 Russell Street, Toronto, Ontario, Canada M5S 3B1. 4 Geology Department, Pomona College, 185 E.
