Glimpses of oceanic lithosphere of the Challenger Deep forearc segment in the southernmost Marianas: The 143°E transect, 5800–4200 m
(Wiley, 2020-06-16)We studied nine samples of igneous rocks from the inner wall of the Mariana Trench above the Challenger Deep from 4150 to 6100 m depth recovered by manned submersible and ROV. Samples from two regions that bracket the Moho ... -
Characterization of Rock Salt Response to Blasting using Terrestrial Laser Scanning Technology
This doctoral research project addresses some of the fundamental aspects for blast design methods in rock salt mines. An experimental field work protocol was devised based on the use of single hole blast (SHB) tests to ... -
Machine Learning in Mineral Exploration: A Tutorial
(Queen's University, 2019)This tutorial aims to demonstrate how to conduct some machine learning methods in geoscience to enhance mineral exploration studies. The document does not intent to present an exhaustive list of all the methods available ... -
Convolutional Neural Networks Architecture: A Tutorial
(Queen's University, 2019)Deep learning techniques have found an increasing number of applications in the field of geosciences. Among the most applied ones, Convolutional Neural Networks stand out by their ability to extract features from grid-like ... -
A Simple, Synthetic and Two Dimensional Geometallurgical Modeling Application
(Queen's University, 2019)Geometallurgy seeks to provide a holistic framework across the mine value chain. Although it is possible to find real world applications in the literature, in most cases the integration is just between geological modeling ... -
Using LSTM and GRU to Predict SAG Mill Energy Consumption
(Queen's University, 2019)In mine operations, comminution is the most demanding energy consumer. Within comminution, semi-autogenous grinding mills are by far the most intensive consumers. Classic techniques to forecast their future energy consumption ... -
Multivariate Geostatistical Simulation using Principal Component Analysis
(Queen's University, 2019)Multivariate geostatistical simulation is aimed at reproducing the statistical relationships between variables and their spatial distribution. We present a methodology whereby grades and a filler variable are transformed ... -
MultiGaussian Kriging: A Review
(Queen's University, 2019)The kriging estimate has an associated kriging variance which measures the variance of the error between the estimate and the true value. However, this measure of uncertainty does not depend on the actual value of the ... -
A Literature Review on P-wave Velocities in Rock Under Compression
(Queen's University, 2019)P-waves are acoustic waves propagated through geological mediums. P-wave velocities are increasingly being used in natural resource industries. The purpose of this paper is to present a literature background on the behavior ... -
A General Approach to the Assessment of Uncertainty in Volumes by Using the Multi-Gaussian Model
(Queen's University, 2019)The goal of this research is to derive an approach to assess uncertainty in an arbitrary volume conditioned by sampling data, without using geostatistical simulation. We have accomplished this goal by deriving an numerical ... -
Modeling the Uncertainty in Geologic Volumes: The Log-Normal Case
(Queen's University, 2019)The aim of the study is to develop a methodology that allows the quantification of the uncertainty in an arbitrary volume conditioned by sampling data, without the use of the traditional geostatistical simulation, which ... -
Updating Geological Codes Through Iterative Jack-Knife
(Queen's University, 2019)We present a methodology to classify spatial data carrying only continuous variables into different categories, where categorical clustering is suitable to be applied to the data. The methodology is based in a very simple ... -
Exploring the RCNN Technique in a Multiple-Point Statistics Framework
(Queen's University, 2019)This work explores the Recursive Convolutional Neural Network (RCNN) technique in terms of describing (1) the inner architecture, (2) the training process and (3) the simulation algorithm in a multiple-point statistics ... -
Knowledge Discovery from Geochemical Data with Supervised and Unsupervised Methods
(Queen's University, 2019)As mineral exploration activities tend to aim at deeper targets, costs per discoveries are getting higher. Therefore, the effective utilization of all the available data is critical in the decision-making process. In recent ... -
Geometallurgical Modeling Framework
(Queen's University, 2019)Geometallurgical modeling allows understanding and transferring the variability of input variables into the downstream processes. In this paper, we present the overview of the geometallurgical modeling framework, and show ... -
An Epeiric Glass Ramp: Permian Low-Latitude Neritic Siliceous Sponge Colonization and its Novel Preservation (Phosphoria Rock Complex)
(Elsevier, 2019-11-29)Glass ramps are shallow-marine depositional settings in which siliceous sponge meadows dominate coastal environments. They are increasingly recognized throughout the Phanerozoic and represent a biosiliceous counterpart to ... -
Autonomous Bathymetric and Magnetic Surveying for Canadian Lakes
Magnetic surveys are an important step in the process of mineral and archaeological exploration. Current magnetic surveying methods include mounting magnetometers to various survey platforms including inhabited airplanes, ... -
Copper Isotopic Analysis in Geological and Biological Reference Materials by MC‐ICP‐MS
(Wiley, 2020-01-24)The characterisation of relative copper isotope amount ratios (δ65Cu) helps constrain a variety of geochemical processes occurring in the geosphere, biosphere and hydrosphere. The accurate and precise determination of δ65Cu ... -
