Mercury in subsurface and mine waters at Aktash ore deposit

International Geology Review, 1971
In a weakly mineralized, weakly alkaline aqueous halo of mercury ores, Hg migrates mainly as a hydroxide and also as complexes from which it cannot be precipitated by H2S. This latter form of “bound mercury” may broaden the halo and dissipate the metal over long distances.

Fluoborite in the Ore-Bearing Skarns of the Aktash Magnetite-Polymetallic Deposit in the Karamazar (Northhern Tajikistan)

Zapiski RMO (Proceedings of the Russian Mineralogical Society), 2023
Fluoborite has been for the first time discovered in magnetite-bearing skarns at the distance of few meters from the contact between dolomite-carbonate and granodiorite of the Aktash deposit. Fluoborite, Mg3(BO3)(F,OH)3, was revealed and studied with optical and electron microscopy and determination of its chemical composition (wt %): MgO 63.29–64.56 ...

The influence of deposit-feeding organisms on sediment stability and community trophic structure

Journal of Marine Research, 2020
Deposit-feeding and suspension-feeding benthos in Buzzards Bay, Massachusetts, show marked spatial separation; suspension feeders are largely confined to sandy or firm mud bottoms while deposit feeders attain high densities on soft muddy substrata.

Trace Element Composition of Igneous and Hydrothermal Magnetite from Porphyry Deposits: Relationship to Deposit Subtypes and Magmatic Affinity

Economic Geology, 2019
The trace element composition of igneous and hydrothermal magnetite from 19 well-studied porphyry Cu ± Au ± Mo, Mo, and W-Mo deposits was measured by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) and then classified by partial

Completing the Banking Union with a European Deposit Insurance Scheme: Who is Afraid of Cross-Subsidisation?

Economic Policy, 2018
This paper investigates the impact and appropriateness of establishing a fully mutualized European deposit insurance scheme (EDIS) using a unique supervisory micro-level data set on euro area banks’ covered deposits and their other liabilities. We find

TRACE ELEMENT SIGNATURE OF PYRITE FROM THE LOS COLORADOS IRON OXIDE-APATITE (IOA) DEPOSIT, CHILE: A MISSING LINK BETWEEN ANDEAN IOA AND IRON OXIDE COPPER-GOLD SYSTEMS?

, 2016
Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the deeper roots of some Andean iron oxide copper-gold (IOCG) systems, their genetic links remain obscure and controversial. A key question when considering an integrated

Magnetite as an Indicator Mineral in the Exploration of Porphyry Deposits: A Case Study in Till near the Mount Polley Cu-Au Deposit, British Columbia, Canada

, 2017
The investigation of this paper focused on whether the composition of hydrothermal ore-related magnetite in till could be used to locate porphyry deposits in terrane where glacial overburden overlies rocks that host porphyry Cu-Au mineralization.
