Temagami Area Rock Art and Indigenous Routes
Zawadzka Temagami Area Rock Art 159 Beyond the Sacred: Temagami Area Rock Art and Indigenous Routes Dagmara Zawadzka The rock art of the Temagami area in northeastern Ontario represents one of the largest concentrations of this form of visual expression on the Canadian Shield. Created by Algonquian-speaking peoples, it is an inextricable part of their cultural landscape. An analysis of the distribution of 40 pictograph sites in relation to traditional routes known as nastawgan has revealed that an overwhelming majority are located on these routes, as well as near narrows, portages, or route intersections. Their location seems to point to their role in the navigation of the landscape. It is argued that rock art acted as a wayfinding landmark; as a marker of places linked to travel rituals; and, ultimately, as a sign of human occupation in the landscape. The tangible and intangible resources within which rock art is steeped demonstrate the relationships that exist among people, places, and the cultural landscape, and they point to the importance of this form of visual expression.

Twblvetrees, F.G.S., and W. F. Petterd, C.M.Z.S. The following Notes lay no claim to be an exhaustive description of our familiar '• diabase" or "dolerite" rock, which plays such an important part in the geology and physical configuration of our Island. The present object is rather to place upon record some inferences drawn from the examination of numerous microscopical sections of speci- mens collected or received from all parts of Tasmania. It is by accumulating the results of observations that stepping stones are formed to more complete knowledge. A glance at Mr. R. M. Johnston's geological map of Tasmania, issued by the Lands Office, will show the share this rock takes in the structure of the Island. It occupies the whole upland area of the Central Tiers. On the northern face of the Tiers—the Western Tiers as they are here called—there is a tongue of the rock prolonged northwards past IMount Claude. At their north-west corner it forms or caps mountains, such as Cradle Mountain (the highest in Tas- mania), Barn Bluff, Mount Pelion West. Eldon Blufi: forms a narrow western extension. Mount Sedgwick is a western out-lier ; Mount Dundas another. In that part of the island it is also found at Mount Heemskirk Falls, and on the Magnet Range, two miles north of the Magnet Mine. Mounts Gell and Hugel are also western out-liers. -

Mechanism and Kinetics of Chalcopyrite Passivation and Depassivation During Ferric and Microbial Leaching
MECHANISM AND KINETICS OF CHALCOPYRITE PASSIVATION AND DEPASSIVATION DURING FERRIC AND MICROBIAL LEACHING By ALAIN FUAMBA TSHILOMBO B.Eng., Faculte Polytechnique, University of Lubumbashi, 1994 M.Sc. , The University of Pretoria, 2000 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY In THE FACULTY OF GRADUATES STUDIES (Department of Materials Engineering) THE UNIVERSITY OF BRITISH COLUMBIA December 2004 ABSTRACT Chalcopyrite is known to be recalcitrant to conventional hydrometallurgical and biohydrometallurgical processes. Formation of passive layers on the chalcopyrite surface results in slow and incomplete leaching. The nature of how these passive layers are formed is the subject of much controversy. The most likely explanation is the formation of polysulphide compounds or copper-rich intermediate products on the chalcopyrite surface. The formation of these products depends mainly on temperature and solution potential. Based on these observations, electrochemical techniques were used to study the behaviour of chalcopyrite under a variety of conditions similar to ferric and microbial leaching. Electrochemical techniques have the advantage over other techniques of measuring properties at the solid-liquid interface. Slow chalcopyrite leaching was mainly observed under the following conditions: > low temperature (25°C) and low potential (0.45 to 0.6 V SCE) > high temperature (65°C) and high potential (above 0.6 V SCE) Leaching was accelerated at high temperature (65°C) under mildly oxidizing conditions (0.45 to 0.55 V SCE). The study also indicated that a polarized chalcopyrite surface inhibits ferric reduction and that the presence of pyrite during chalcopyrite leaching can be beneficial. The electrochemical study was validated in leaching tests carried out in a stirred-tank reactor with fine chalcopyrite particles.
