“…In comparison, the significantly narrow ranges of sulfides with a cluster toward positive δ 34 S values in both deposits are similar to those of several ancient VHMS deposits, including the Osborne Lake deposit in the Snow Lake area, Canada (-1.1‰ to +6.0‰; Sangameshwar, 1972), the El Cobre deposit, Cuba (-1.4‰ to +7.3‰; Cazañas et al, 2003), the Mount Morgan deposit, Australia (-1.6‰ to +5.3‰; Ulrich et al, 2002), the Lewis Ponds, Mount Bulga, Belara and Accost deposits in the Lachlan Fold Belt, New South Wales (range of -1.7‰ to +5.9‰; Downes and Seccombe, 2004). However, the abundance of significant low δ 34 S values in sulfides at the Bukit Ketaya deposit is also probably comparable with a δ 34 S signature exhibited by the Mount Lyell deposits, Tasmania (-10‰ to +10‰; Huston et al, 2011).…”

“…Natural geological settings: metamorphic rocks, sedimentary rocks, volcanic H 2 S, volcanic SO 2 and granites- Hoefs (2004). igneous rocks most likely the volcanic host rocks at both deposits. Nevertheless, a direct magmatic source seems unlikely because a direct magmatic contribution would be more effective in supplying metals, in particular the Cu, Au, Bi, and Te, to VHMS deposits (Large, 1992), and is significant in the formation of giant VHMS deposits (Ulrich et al, 2002).…”

Sulfur isotope data from sulfide and sulfate minerals have been measured from the two typical examples of the Permian volcanic-hosted massive sulfide (VHMS) deposits at the Tasik Chini district in the Central Belt of Peninsular Malaysia. In this study, we present the sulfur isotope data for 33 sulfide minerals and 23 barite samples from two VHMS deposits in the Tasik Chini district. Sulfides show a narrow range of sulfur values from -2.9‰ to +8.30‰, which can be interpreted to be derived from a mixed sulfur source of reduced seawater sulfate with the possible addition of magmatic sulfur. Sulfate sulfur in barites yields a δ 34 S range between 11‰ and 22‰, which is comparable to that of Permian seawater sulfate. Sulfur isotope results obtained for the VHMS deposits in the Tasik Chini district suggest that the source of ore fluids during the formation of the Tasik Chini VHMS deposit is a seawater-dominated fluid with probably minor magmatic fluid input. This is similar to VHMS associated with ancient and modern submarine hydrothermal systems.

Abstract. The Xiongcun Cu-Zn-Au deposit lies in the western segment of the Gangdese porphyry copper belt and in the forearc basin of the Southern Gangdese volcanic arc. The deposit is hosted by Cretaceous marine intermediate and basic volcanic clastic rocks that filled a supra-subduction forearc basin. The mineralized alteration zone is 2 km in length and varies in width from 100 m to 400 m with an average of about 200 m. The mineralized horizon is divided into a lower stringer mineralization and upper massive, submassive and banded mineralization. Laminated and banded mineralization lies in the hanging wall. Weak sulfidation is documented in the footwall. In addition, some late veins and lenticular sulfide bodies cut the early formed sulfide horizons. The most prospective ore bodies are developed in the upper mineralization horizon. Alteration is zoned with distal propylitization and proximal silicification, sericitization ± chrolitization in the ore body. Fluid inclusion analysis, sulphur isotopes, and trace elements of sulfides reveal that the deposit has the similar features compared with ancient volcanic-hosted massive sulfide deposits (VHMS) and modern active chimney. Based on these characteristics, we propose the deposit is a deformed VHMStype deposit that formed in the forearc of the Gangdese volcanomagmatic arc during Mesozoic subduction. Second stage veins, inferred to form during collision between the India subcontinent and Eurasia cut the VHMS deposit prior to or simultaneous with intrusion of a post-mineral Himalayan-age diorite porphyries.

In abandoned mine sites, i.e., mine sites where mining operations have ended, wide spread contaminations are often evident, but the potential sources and pathways of contamination especially through the subsurface, are difficult to identify due to inadequate and sparse geochemical measurements available. Therefore, it is essential to design and implement a planned monitoring network to obtain essential information required for establishing the potential contamination source locations, i.e., waste dumps, tailing dams, pits and possible pathways through the subsurface, and to design a remediation strategy for rehabilitation. This study presents an illustrative application of modeling the flow and transport processes and monitoring network design in a study area hydrogeologically resembling an abandoned mine site in Queensland, Australia. In this preliminary study, the contaminant transport process modeled does not incorporate the reactive geochemistry of the contaminants. The transport process is modeled considering a generic conservative contaminant for the illustrative purpose of showing the potential application of an optimal monitoring design methodology. This study aims to design optimal monitoring network to: 1) minimize the contaminant solute mass estimation error; 2) locate the plume boundary; 3) select B. Datta et al. 47the monitoring locations with (potentially) high concentrations. A linked simulation optimization based methodology is utilized for optimal monitoring network design. The methodology is applied utilizing a recently developed software package CARE-GWMND, developed at James Cook University for optimal monitoring network design. Given the complexity of the groundwater systems and the sparsity of pollutant concentration observation data from the field, this software is capable of simulating the groundwater flow and solute transport with spatial interpolation of data from a sparse set of available data, and it utilizes the optimization algorithm to determine optimum locations for implementing monitoring wells.
