Uplift history of the Troodos ophiolite inferred from integrating thermomechanical models, submarine and deltaic fan clast content and serpentinites

Uplift of the Troodos ophiolite from its time of formation (~90 Ma) to the present-day is currently poorly constrained, due to its complex multi-phase uplift history involving multiple uplift mechanisms. The aim of this study is to quantify the amount of uplift and uplift rates in the different phases, to construct a more complete timeline of...

The evolution of Troodos ophiolite dikes and their relationship with the spreading ridge-transform fault system on Cyprus

As windows into fossil oceanic crust, ophiolites provide unique information on processes such as crust formation, seafloor spreading and hydrothermal alteration. The Troodos ophiolite is located on Cyprus, an island on the southern Anatolian plate in the eastern Mediterranean. The ophiolite formed during the Late Cretaceous (90-92 Ma) and...

A multiscale characterisation of the Early Jurassic upper member of the McCarthy Formation, Southcentral Alaska

Ocean circulation, reflected in bottom current strength, is an essential factor in determining the global climate. Therefore, the deposits of ancient bottom currents are of great paleoclimatic importance. The sparse evidence of bottom currents in the Mesozoic has been linked to sluggish ocean circulation. Arguably, the sparse evidence is caused...

Bridging geological and seismic modelling: Study of petrophysical properties and their trends on outcrop analogue

Within the project Seismic property characterization for stratigraphic architecture analysis and static geomodel conditioning, a major challenge is populating the forward stratigraphic modelling (FSM) realisations with petrophysical properties to perform forward seismic modelling. FSM provides information about grain size and facies distribution...

Linking natural fractures to karst cave development: A case study combining drone imagery, a natural cave network and numerical modelling

In carbonate rocks, channelized fluid flow through fracture conduits can result in the development of large and connected karst networks. These cavity systems have been found in multiple hydrocarbon and geothermal reservoirs, and are often associated with high-permeability zones, but also pose significant challenges in drilling and reservoir...

Geologic origin of arsenic contamination along the Sone and Ganges Rivers, Bihar, India

This report describes the process and result of a fieldwork project in Bhojpur district, Bihar, India. The project concerns geological research in the state of Bihar, India with the purpose to map the hydrogeochemical variability in space and time related to transport of arsenic in the subsurface. Data obtained and implemented during this...

Revision of the family Gastrodoridae (Crustacea, Decapoda), with description of the first species from The Cretaceous

Representatives of the family Gastrodoridae were exclusively known from Jurassic deposits in central Europe. Here, the first Cretaceous species, Gastrodorus cretahispanicus n. sp., is recorded from reefal strata of the Eguino Formation (Albeniz Unit) of Albian-Cenomanian age, in western Navarra (northern Spain). Not only does the occurrence of...

Sedimentology and 3D architecture of a bioclastic calcarenite complex on Favignana, southern Italy: Implications for reservoir modelling

The island of Favignana provides an exceptional three-dimensional insight in the architecture of a Lower Pleistocene bioclastic calcarenite complex. Due to the degree of quarrying, a large amount of outcrops is available in the eastern part of the island. Two campaigns resulted in the logging of stratigraphic sections, recording of sedimentary...

Modeling 3D Sedimentary Architecture of Glacio-Fluvial Valley Fills: Report Concerning Scientific Communication of MSc Thesis Results. For the Benefit of the Stichting Molengraaff Fonds.

The depositional architecture of valley fill systems is controlled by interaction of boundary conditions: ice cap and drainage area changes influence initial topography and river water and sediment discharge and thus control the sediment supply, whereas sea-level fluctuation and isostatic rebound control the accommodation rate. Glacial and...

Capillary Pressure and Wettability Behavior of Coal - Water - Carbon dioxide System

Enhanced Coal Bed Methane (ECBM) recovery techniques, based on carbon dioxide injection, have been proposed for the recovery of larger fraction of methane in place. Laboratory studies and recent pilot field tests demonstrate that CO2 injection has the potential to enhance coal bed methane recovery through displacement desorption mechanism with...

Time-lapse GPR measurement to study the imaging operator

This paper aims at improving imaging algorithms for ground penetrating radar data. Recent efforts try to achieve this by incorporating the electromagnetic vector propagation, describing the source and receiver antenna as far field point-source radiation patterns. Here, we show that a theoretically sound imaging operator can be constructed based...

Batchleaching in Bamboo Creek Western Australia

Batchleaching is a low cost way of treating gold ore. First a basin is built with dirtwalls and plastic. Next the basin is filled with tailings together with some of the chemicals. Cyanide is put on top of the batch and a substantial amount of water is added, enough to start circulation. Water with dissolved cyanide slowly penetrates through the...

Report on fieldwork Turkey the mini-Sosie method

This report is written because of my practical training in Turkey in the period of the 25th of June untill the 20th of August. As a geophysical trainee I have worked for M.T.A. – Maden, Tetkik ve Arama -, a Turkish government founded company. The survey was done with the mini-Sosie method, a vibration system used here for shallow-land reflection...
