    Abstract: The Paleocene lava succession of the Faroe Islands Basalt Group (FIBG), which is a part of the North Atlantic Igneous Province (NAIP), is intruded by numerous basaltic sills. These can be grouped into three main categories according to their geochemical characteristics: A low-TiO2 sill category (TiO2 = 0.7-0.9), a relatively high-TiO2 sill category... Show More

    Abstract: Basin modelling is an essential research tool that aids geologists improve the description and analysis of subsurface activity. The central region of the Andaman Sea back arc basin is a potential oil and gas prospect. Herein, two-dimension present-day maturity models are constructed from four seismic sections of the study area using Basin Mod soft... Show More
  • An Alternative Structural Model for the Development of the Cape Fold Belt Syntaxis and Groundwater Potential

    Abstract: The syntaxis separates the eastern and western branches of the Cape Fold Belt, South Africa. A satisfactory and holistic solution remains unresolved. This investigation is to develop an alternative hypothesis for the development of the syntaxis. Because macroscopic fold structures are considered most relevant in resolving a tectonic solution on sub... Show More

    Abstract: The present research describes a 1D inversion scheme for interpretation of large loop TEM data acquired using offset loop configuration due to a large loop source, over the layered earth models. The inversion is based on a non-linear least square method that generates a smooth layered earth model by minimizing the residual misfit function in an ite... Show More
  • Spatial Prediction of Soil Organic Matter Using Geostatistics and Topographic Unit Zoning Integrated in GIS: A Case Study

    Abstract: The spatial distribution of soil organic matter (SOM) has a close connection with topography. To understand the effects of topographic synergy effects in traditional geostatistic methods, the influence of topography is considered in SOM geostatistic studies by combining geographic unit zoning and spatial prediction. We explored the changes in the S... Show More
