This paper reports a finite element analysis of the flexural behaviour of concrete-filled steel tubular members with elliptical section. A set of test data were used to verify the FE modeling. generally, good agreement was achieved. Typical curves of moment (M) versus deflection at mid-span (um), as well as stress distributions of steel tube and concrete of the composite members were compared and discussed. The results clearly show that the FE model is available for predicting the load-bearing capacities and the failure modes of the specimens. © (2014) Trans Tech Publications, Switzerland.

The Aitik Cu-Au-Ag(Mo)deposit in the Gällivare area of northern Sweden is the largest open pit copper and gold deposit in Europe, and is also the biggest gold deposit in Sweden. The geology of the Aitik deposit comprises Palaeoproterozoic garnetbearing biotite schist/gneiss, quartz-muscovite-sericite schist, mica-schist, porphyritic quartz monzodiorite and pegmatite. The copper and gold mineralization areas are mainly located in Palaeoproterozoic volcaniclastic rocks (named Sweden-Finland rock series) and volcano-sedimentary intrusive veins (or stocks) and exhibit veined, stockwork and veinlet dissemination forms, constituting stratified, lenticular, and chambered orebodies. A porphyritic quartz monzodiorite intrusion of subvolcanic origin, which is a composite body, is situated in the structural footwall of the orebody, and its age coincides with the age obtained for the subduction- related Haparanda suite of granitoids in Norrbotten. It is proposed that the Aitik deposit is a product of high-salinity fluids, and represents a Palaeoproterozoic strongly metamorphosed porphyry copper deposit affected by a regional IOCG-type hydrothermal event, and the mineralization experienced a period of 160Ma. Consequently, the Aitik deposit might represent a mixed ore system where later regional IOCG mineralization was superimposed upon the early copper mineralization of porphyry type. ©, 2015, Science Press.

Gold deposits in northern Finland occur like numerous stars in Paleoproterozoic Central Lapland greenbelt (CLGB) and Kuusamo-Perapohjaschist greenbelt. Gold deposits in northern Finland can be divided into three categories: orogenic gold deposits, iron oxide Cu-Au deposits (IOCG) and placer gold deposits. Most of orogenic gold deposits are distributed mainly over CLGB and Kuusamo-Perapohjaschist greenbelt. The most common ore minerals of orogenic gold deposits are pyrite, arsenopyrite, chalcopyrite and pyrrhotite, whereas the accessory minerals are mainly galena, sphalerite and tetrahedrite. The wall rock alterations of orogenic gold deposits mainly include albitization, sericitization, biotitization, carbonatization and, to some extent, chloritization. The orogenic gold deposits have many similarities in mineralization, and main controlling factors include tectonics, lithology and orogenic metamorphism. The IOCG deposits in northern Finland are distributed mainly in the Clariant area of west CLGB, and the wall rocks are albite-anthophyllite rocks with strong wall rock alteration and obvious zonation. Elements concentrated in the ore are Ag, Au, Bi, Co, Cu, Fe, Mo, LREE, S, Se, and Te. The mineralization of IOCG deposits was closely related to magmatic hydrothermal activity and structure. Placer gold deposits in northern Finland comprise paleoplacer deposits and placer deposits which are mainly distributed in the northeast of CLGB.Gold deposits in northern Finland are of great significance for the mineral exploration in Arctic Circle and adjacent areas; on the other hand, the study of ore deposits in northern Finland is of reference value for the gold exporation work in such areas as the Jiaodong Peninsula, the northern margin of North China Craton, Xiao Qinling and Qinling area and northern Xinjiang in China. ©, 2015, Science Press.

Abstract: Located in east-central part of Alaska, USA, the Fort Knox gold deposit is one of the largest superlarge gold deposits in Arctic circle. The study of its geological setting, orebody features and ore genesis indicates that the deposit was mainly formed in the contact zone of Precambrian-early Paleozioc greenschist intruded by Cretaceous-Paleogene granitic rocks and prominently controlled by tectonomagmatic activity. It has an area of 1100×600m2 at surface but is gradually reduced with the depth. Unlike other intrusion-related gold deposits, the hydrothermal alteration of the deposit is well developed. Gold mineralization has close relationship with K-feldspar, albite, sericite and propylitization. Isotope chronologic evidence suggests that the metallogenic epoch is late Cretaceous-Paleogene (92.5±0.2Ma), suggesting a product of multi-stage magmatism. Based on the characteristics of isotopic data, oreforming fluid and wall rock alteration, the authors have reached the conclusion that the ore-forming materials were mainly derived from granitic magma, the metallogenic process was related to the oxidized intermediate-acid intrusions and fluid activities, and hence the deposit should belong to the intrusion-related gold deposit. ©, 2015, Science Press.
