Metamorphism and metasomatism at king Island Scheelite Mine1

Abstract The King Island Scheelite Mine lies in the contact aureole of a granodiorite stock. Its open cut and numerous drill cores expose a contact metamorphosed and metasomatized series of finely interbedded argillaceous and calcareous sediments, with interleaved flows of picrite‐basalt and basic pyroclastics, the scheelite ore being limited to two limestone horizons. The range and gradation in composition of the original rocks has resulted in an unusual variety of metamorphic rocks, including forsterite‐phlogopite‐spinel‐tremolite hornfels, antho‐phyllite‐cordierite hornfels, biotite hornfels, actinolite hornfels, a variety of calc‐flinta, and marbles. The original sedimentation gave rise to a rapid alternation of limestone and shale, many times repeated, and during metamorphism these rocks reacted with each other to produce narrow bands of calc‐flinta. Subsequent pyrometasomatism selectively converted the greater part of the marble beds to scheelite‐bearing andradite skarn, leaving the various hornfels and calc‐flinta very little affected. The replacement of the marble was a volume for volume process, and the conversion of 1,000,000 tons of marble to average grade ore involved the introduction of about 350,000 tons of SiO2, 250,000 tons of Fe2O3, 55,000 tons A12O3, 30,000 tons of H2O and 82,500 tons of CaO. The temperature of the contact metamorphism attained over 500° C., and the rocks cooled to about 400° C. before the pyrometasomatism occurred. The rocks giving rise to the various hornfels underwent varying degrees of contraction during metamorphism, whereas the limestones probably expanded during metamorphism, and became more permeable to solutions.

The Trophic Status of Port John Lake, British Columbia

Port John Lake is situated on King Island on the central British Columbia coast. Area is about 0.35 square miles (910,000 sq. m.). The drainage basin is 3.6 square miles (9.3 sq. km.) with an igneous foundation supporting a coniferous forest. Annual precipitation is 116 inches (295.5 cm.). An oligotrophic lake, it has a volume development of 1.53 and a mean depth of 82.2 feet (25.1 m.). The thermal stratification is second order, temperate, of the Whipple classification. The summer heat income is approximately 11,000 gram-calories per sq. cm. The ratio of O2 in the hypolimnion to O2 in the epilimnion is 6.58. Total dissolved solids are 39 ppm. at the lake surface.Large amounts of organic matter are washed into the lake imposing a potential stress on its oligotrophy. However, dredge and net collections, which are dominated by chironomids and cladocerans, respectively, contained very few organisms. Plankton was most abundant in the surface water.Low production of organisms is partly the result of the heavy rainfall which dilutes the trophic stratum above the hypolimnion, and the small amount of sunlight reaching the lake.

A Note on the Occurrence of Intergrowth between Diopsidic Augite and Albite and of Hydrogrossular from King Island, Tasmania

AbstractA description is given of an intergrowth between augite and albite found in Spilitic lavas from King Island, Tasmania. Hydrogrossular is found pseudomorphing olivine and also in veins and vesicles in certain rocks of the same volcanic suite.

Seasonal Variations in the Vitamin a Content of Victorian Butterfat

The total vitamin A potency of butterfat (dertved from cheese or butter) has been determined on samples from three different Victorian districts and from King Island in Bass Strait in 1945 and 1947-48. Carotene was determined colorimetrically and the Carr-Price test was used for vitamin A. The glycerol dichlorhydrin reagent was too insensitive.

Spilitic Rocks in New Zealand

Prior to a discovery made recently by the writer, of spilitic rocks at Great King Island, the largest member of the Three Kings group of islands, about 26 miles north-west of the north-west extremity of the mainland of New Zealand, such rocks had not previously been found in this latter country. Some account of the types represented at Great King Island may therefore be welcome, particularly since Gilluly's (1935) recent comprehensive paper has focused attention on spilites and their associations.

New Australia-Tasmania Submarine Cable

THE new submarine cable which was successfully laid across the Bass Strait last November marks a notable advance in the technique of submarine cable transmission. Before laying this cable, the Australian Government made a searching inquiry into the relative merits of radio and cable systems of communication, and came to the conclusion that for the objects in view the cable system was the more desirable as it is more trustworthy and easier to make the messages secret. In the Engineering Supplement to the Siemens Magazine of January, a technical description is given of this new cable. It links the telephone and telegraph service of the mainland of Australia with Tasmania. Its length of 161 nautical miles is divided into two sections. The northern section, 79 miles in length, joins King Island to Apollo Bay, Victoria, and then by overhead lines and underground cables joins the trunk exchange at Melbourne. The southern section from King Island goes to the northern coast of Tasmania and then by land line to the Launceston exchange. Inter-connexion is thus effected with the existing network of communications in Australia and Tasmania. This cable, although it has only one insulated conductor, allows no less than five telephone and seven high-speed telegraph channels to be operated simultaneously. In addition, it provides for the transmission of a broadcast programme. Subscribers in Tasmania can now communicate directly with Great Britain by telephone. The adoption of a high-frequency carrier system was influenced by the fact that it is easy to repair. Cable ships are not always available for immediate service in Australian waters and this type of cable is the easiest to repair. There are already two carrier frequency submarine cables in operation. One connects Teneriffe with Gran Canaria, a distance of forty miles, and the other Key-West to Havana, a distance of 109 miles. Both these cables operate only three telephone circuits.

MR. W. H. Dudley Le Souëf

THE October issue of the Victorian Naturalist contains an appreciation of the life and work of Mr. W. H. Dudley Le Souef, Director of the Melbourne Zoological Gardens, who died on September 6, at the age of sixty-six. Mr. Le Souef was a prominent member of the Field Naturalists' Club of Victoria, and his extensive travels over the Australian continent studying the habits of or collecting native animals, birds, etc., provided material for numerous papers which he contributed to the Club. In most of these the main interest centred on the birds, but other branches of natural history were not neglected. He compiled a list of Victorian reptiles published in the Victorian Naturalist of 1884, and was the author, with Mr. A. H. S. Lucas, of two standard works, “The Animals of Australia,” and “The Birds of Australia.” In another volume, “Wild Life in Australia,” he brought together the accounts of his many expeditions which had appeared from time to time in the Victorian Naturalist and the Emu, the organ of the Australasian Ornithologists' Union, of which he was one of the founders. His interest in Australian ethnology led him to take part also in expeditions to King Island, the Kent Group, and to Albatross Island. Mr. Le Souef was an enthusiastic student of Nature, who was always willing to bring natural history before an audience, generally illustrating his lectures by lantern slides from his own photographs. For many years he was Assistant Director of the Melbourne Zoological Gardens, and in 1902 he was made Director, in succession to his father. Under his care the Gardens have become the most important collection oi animals in Australia.
