The British Geological Survey Rock Classification Scheme, its representation…

Controlled vocabularies are critical to constructing FAIR (findable, accessible, interoperable, re-useable) data. One of the most widely required, yet complex, vocabularies in earth science is for rock and sediment type, or ‘lithology’. Since 1999 the British Geological Survey has used its own Rock Classification Scheme in many of its workflows and products including the national digital ge…

Uncertainties in 3-D stochastic geological modeling of fictive grain size dis…

Geological 3-D models are very useful tools to predict subsurface properties. However, they are always subject to uncertainties, starting from the primary data. To ensure the reliability of the model outputs and, thus, to support the decision-making process, the incorporation and quantification of uncertainties have to be integrated into the geo-modeling strategies. Among all modeling approache…

Towards a workflow to evaluate geological layering uncertainty on CO2 injecti…

We propose a workflow for updating 3D geological meshed models to test different layering scenarios and to assess their impact on the simulation of injection. This workflow operates on a tetrahedral mesh that encodes rock unit information as well as rock physical properties. The alternative layering meshes are built by modifying the input mesh and inserting a new horizon defined by a scalar …

Interactive web mapping tools and custom subsurface cross-sections for interd…

Using Python-based geospatial analytics, open-source web mapping technologies, geophysical data models, and subsurface stratigraphy models from the Regional Geology Geologic Framework Model database assembled by Los Alamos National Laboratory, we developed a suite of web-based geologic investigation tools to identify and understand subsurface structures and geophysical properties concerning sal…

Probabilistic knowledge-based characterization of conceptual geological models

The construction of conceptual geological models is an essential task in petroleum exploration, especially during the early stages of investment, when evidence about the subsurface is limited. In this task, geoscientists recreate the most likely geological scenarios that led to potential accumulation of reserves in a target block, based on past experience, historical analogues, and interpreted …

Visualization of evolutionary relationships through geologic time in Timescal…

Evolutionary trees showing interpretations of the divergences, lineages, extinctions and relative abundances of life forms through geologic time provide a very useful visualization for both public audiences and research communities. The Java-based TimeScale Creator platform was originally designed to present graphics of Earth history with a streamlined interface. We have added an evolutionary t…

Unsupervised clustering of LA-ICP-MS raster map data for geological interpret…

Raster element concentration maps created using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) can be used to interpret microscale compositional and textural domains within mineral grains. Raster maps are typically evaluated element by element; however, application of statistical techniques (such as cluster analysis) can enhance the generation of geochemical domains to …

Warisan geologi Krakatau: pembentuk akhir Selat Sunda

Warisan geologi adalah fenomena geologi yang terbentuk secara alami, memiliki nilai sangat tinggi dan luar biasa karena merepresentasikan rangkaian rekaman proses geologi yang saling berhubungan, sehingga secara keilmuan merupakan bagian penting dari sejarah dinamika bumi. Saat ini pemahaman terhadap warisan geologi mulai mengglobal ketika banyak rekam jejak penting sejarah bumi semakin teranca…
