modelling of marble ore deposits

Methodology for the Estimation and Classification of White Marble

The steps of the methodology are illustrated via a case study of white marble ore deposit. One of the innovative aspects of the proposed method is the spatial interpolation of the whiteness, which is assessed from the drill cores or borehole walls.Three-dimensional (3D) models of orebodies and deposits can provide strong support for quantitative evaluation of mineral resources. However, 3D modeling of A Feature-Enhanced MPS Approach to Reconstruct 3D Deposit Models

Introduction to the special issue on spatial modelling and

Modelling offers a means of simulating and analysing ore-forming processes and their mappable expressions. This knowledge can then be used to build a predictive Stable isotope systematics and the geology of these deposits indicate two distinct sedimentary exhalative (Sedex) settings: marble-hosted deposits associated with Stable isotope (C, O, S, and Zn) geochemistry of marble

Machine Learning-Based 3D Modeling of Mineral Prospectivity Mapping

Successful delineation of high potential targets for exploration in maturely-explored orefields is still a tough challenge. A reliable prediction model achieved by integration of various ore-related geological factors and exploration information in the 3D space is an effective approach to deal with this challenge. The Anqing orefield has been Furthermore, 3D metallogenic prediction based on 3D geological modeling and fault ore-controlling law has achieved important research achievements in many areas of the world [12,13,14,15,16,17,18,19].
