Petrogenesis of Ophiolite Suites in Borneo Island and Comparisons with the Zambales (Philippines) and Othrys (Greece) Ophiolites: Possible implications on the Genesis of Abiotic Methane

Ophiolites represent remnants of the Earth's Upper Mantle and Oceanic Crust. Knowledge of their geotectonic evolution and petrogenesis are considered as fundamental keys to the reconstruction of the Earth's history and geotectonic evolution, as they comprise huge and important parts of the Earth's interior. Recently, it has been suggested that these rocks are responsible for the production and exhalation of methane of abiotic origin, which is a theme of growing interest. The present study deals with the detailed investigation of the Borneo ophiolite suite, aiming to unravel the complex geological history of Borneo Island with several implications on the geological development of Malaysia. Geological mapping in certain areas of interest in the Sabah region (Pulau Malawali, Kundasang, Ranau, Telupid, Beluran, please see map provided), collection and preparation of specimens, as well as their thorough microscopic investigation, employing polarising and Scanning Electron Microscope techniques, will be performed. Gas emissions from the ophiolite will be analysed, in order to test the hypothesis for the production of abiotic methane. The proposed research aims at: (i) unraveling the genesis and evolution of the Ancient Mantle and Oceanic Crust of the area of Borneo from the acquisition of data during a thorough petrological investigation, and (ii) investigating the role of these rocks in the formation of the unconventional production of abiotic methane.

A Pilot Geochemical Atlas for Resource Exploration and Environmental Management in the Brunei-Muara District, Brunei Darussalam

Geochemical mapping of large regions is a challenge for applied geoscientists as it is a fundamental tool for the exploration of a plethora of Earth resources, as well as for environmental monitoring and land management. For this reason, regional-, national- and global-scale geochemical mapping projects have been carried out in various countries the last decades (e.g. Geochemical Map of Europe, USA, large regions of Africa, etc.).. The current project is proposed to cover the District of Brunei-Muara as a first effort to construct a similar Atlas in Brunei Darussalam. The area is dominated by sedimentary formations of Miocene to Quaternary age and characterised by various geological units, which have been accumulated from the discharge of ancient and modern rivers and their interaction with a marine environment. A large number of samples will be collected and analysed in order to highlight potential geochemical organic and inorganic anomalies. Subsequent interpretation of these anomalies will lead to implications regarding: (i) the potential existence of economic resources, (ii) environmental applications (e.g. biosorbents of pollutants, waste filters), iii) adverse environmental impacts (anthropogenic and natural) and the consequences to public health, and (iv) the provenance of the sediments and consequently the geological history of Brunei Darussalam.

The Last 10,000 Years: Unravelling the Holocene Geological and Ecological History of Brunei Darussalam by Decoding Peatlands

Tropical peatlands are under stress worldwide and Brunei Darussalam hosts some of the last undisturbed ones in the world. They require special attention and environmental protection, as they are significant sinks and sources of carbon and freshwater but above all they comprise important ecosystems governing the biodiversity of Borneo. The Project aims at investigating the stratigraphic structure of peatlands in Brunei Darussalam, in an effort to obtain geological, and palaeoecological information from them. This will enable us to unravel the recent geological and ecological history of Brunei Darussalam for the first time with a high scale of resolution. The Project also aims to increase awareness of the natural heritage of Brunei Darussalam and to guide the necessary actions for integrated environmental protection including the conservation of some endangered plant species. We will use modern techniques and science for environmental management. A well-designed methodology will eventually result in the production of a series of maps, which will include the geological and ecological data to be used for future conservation and research activities.
