Conference Paper
Manganese and ferromanganese oxyhydroxide (OH) deposits are typically rich in Fe (Fe2+ or Fe3+) and/or Mn (Mn2+, Mn3+ or Mn4+) associated with aqueous environments. In the oceans, they usually occur as nodules, crusts, and massive beds. They can be formed by diagenetic, hydrogenetic, hydrothermal, or mixed-processes [1]. Hydrothermal OH deposits ca...

A 1:12,000 geological map of the Macao Special Administrative Region has been produced through detailed field work supported by petrographic, mineralogical, geochronological and geochemical data obtained in previous studies. This map aims to represent a reliable tool to understand the geological evolution of the region and for management of the ter...
Data
The new geological map of Macao represents an accurate and updated basis for understanding the geological evolution of this area of SE China. The map has relevance for the understanding of the Late Mesozoic magmatic evolution in the region, as it provides new insights into the distribution of magmatic rocks, at large scale (1:12,000), in this area...
Conference Paper
The Saldanha hydrothermal field is located at the top of a mount in the Mid-Atlantic Ridge (MAR, 36º34'N, 32º26'W, ~ 2200m). The field is covered by pelagic sediment from where transparent and weak fluids vent through small orifices. Oxyhydroxides (OH) occur mainly within the top of that sediment cover, forming crusts containing millimetric micro-c...

A closer look into the different hydrothermal fields studied in the SWIMAR project, description and goals of said project.
Presentation
The mineral deposit of Feitais is an enormous sulphide mineral deposit, with massive and stockwork ores of copper and zinc, which is located in the Iberian Pyrite Strip, under the village of Aljustrel. This deposit is currently mined at the Aljustrel Mines by the company ALMINA that made available for this study, data from boreholes and hand sample...

Project
The project brings together researchers in Mainland China, Macao and Europe to investigate the role of ultramafic-hosted hydrothermal systems in the formation of massive sulphide deposits. The project provides an excellent opportunity to combine samples from ultramafic fields from MAR, collected by the European partners, and from SWIR, collected by the Chinese partners, to take a comparative and original approach to this question.
Project
The project will allow, for the first time as far as we are aware, to establish in Macao a research line dedicated to the study of the deep-sea, with the collaboration of established research centres from China and Europe. The comparison of SWIR and MAR fields represents an excellent opportunity to advance our knowledge on the still poorly known ultramafic hydrothermal systems through the development of synergies between researchers in mainland China, Macao and Europe. The project aim to contribute: (1) to improve the understanding of the geochemical and mineralogical changes that take place within hydrothermal systems related with ultramafic settings; (2) to understand the role of serpentinization processes in ore forming minerals; (3) to provide new insights into the formation of SMS deposits and characterize the main differences between mafic and ultramafic hydrothermal systems in the formation of seafloor ore deposits. Moreover, by characterizing the chemical processes operating in this type of systems the project aims to contribute towards the development of new survey methods based on the geochemical signatures of ultramafic-hosted hydrothermal fields. Additional collaborations of other groups are welcome.

超基性岩系海底熱泉系統於海床熱液礦床扮演之角色:以 SWIR 及 MAR 熱泉系統相互比較為例 The project brings together researchers in Mainland China, Macao and Europe to investigate the role of ultramafic-hosted hydrothermal systems in the formation of massive sulphide deposits. The project provides an excellent opportunity to combine samples from ultramafic fields from MAR, collected by the European partners, and from SWIR, collected by the Chinese partners, to take a comparative and original approach to this question.
