Textural, Compositional, and Sulfur Isotope Variations of Sulfide Minerals in the Red Dog Zn-Pb-Ag Deposits, Brooks Range, Alaska: Implications for Ore Formation
The Red Dog Zn-Pb deposits are hosted in organic-rich mudstone and shale of the Mississippian Kuna Formation. A complex mineralization history is defined by four sphalerite types or stages: (1) early brown sphalerite, (2) yellow-brown sphalerite, (3) red-brown sphalerite, and (4) late tan sphalerite. Stages 2 and 3 constitute the main ore-forming event and are volumetrically the most important....
متن کاملBarite, Hematite and Cinnabar Ore Deposits in the Dusina Area, Mid-bosnian Schist Mountains
In the Dusina area, which is built up of Lower Palaeozoic metasediments, Devonian carbonate complex and Upper Palaeozoic metarhyolites unconformably overlain by Upper Permian sediments, numerous ore occurrences have been investigated: (a) "stratabound" metamorphic hematite deposits in the pre-Devonian metasediments; (b) epigenetic veins and pipes of barite (& calcite) with accessory Hg-tetrahed...
متن کاملMineral chemistry of sulfide and sulfosalt minerals in the Cheshmeh-Noghreh barite (gold- silver) deposit, Sabzevar subzone, NE Kashmar
The Sebandoon Barite (gold-silver) deposit is located about 20 km NW of the Kashmar in the Central Iran. The rock units exposed in the area consist of Eocene volcano-sedimentary sequences of lithic tuff, rhyolitic tuff, tuffaceouce shale, lapilli tuff and agglomerate associated with pyroxene andesite and trachyandesite. The barite is composed of lenticular, banded and stockwork mineralization a...
متن کاملGeochemical characteristics of barite occurrences in the Palaeozoic complex of South-eastern Bosnia and their relationship to the barite deposits of the Mid-Bosnian Schist Mountains
In Palaeozoic rocks of South-eastern Bosnia (SEB) there are numerous, but very small vein and replacement barite ore deposits containing up to 10% Pb-Zn-Fe-Cu sulphides. Their geochemical characteristics are compared with large barite monosulphide (Hg-tetrahedrite) ore deposits in Mid-Bosnian Schist Mountains (MBSM). The 87Sr/86Sr isotope ratios in the barites of both areas are very similar, (0...
متن کاملGeochemistry of Oxygen and Carbon Stable Isotopes in Non-Sulfide Zn-Pb Deposits, Case Study: Chah-Talkh non-Sulfide Zn-PbDeposit (Sirjan- South of Iran)
Submitted: Jul 19, 2013; Accepted: Sep 3, 2013; Published: Sep 11, 2013 Abstract: The study of isotopic ratios of oxygen and carbon has gained importance to determine the origin of ore bearing fluids, carbon origin and also to determine the formation temperature of non-sulfide lead and zinc minerals. In order to determine the origin of fluids and carbon existing in zinc carbonate minerals in Ch...
