Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining metallurgical industry Eastern Kazakhstan. To substantiate scientific background exploration, we study microinclusions minerals from rare-metal fields, as well trace-element patterns ores their hosts that may mark mineralization. The revealed compositions gold-bearing sulfide a number typ...
The Zarshuran Carlin-like gold deposit is located at the Takab Metallogenic belt in the northern part of the Sanandaj-Sirjan zone, NW Iran. The high-grade ore bodies are mainly hosted by black shale and cream to gray massive limestone along the NNE-trending extensional fault/fracture zones. The aim of this investigation was to determine and separate the gold mineralized stages based on the surf...
This paper describes occurrences of low grade, disseminated gold in sedimentary rocks and alkalic intrusions in the vicinity of the Howell Creek Structure (HCS; Price,1964) of southeastern British Columbia. The study is part of the B.C. Geological Surveys ongoing Sediment-hosted Gold Project, which is examining occurrences throughout the province which may have similarities to gold deposits in...
