Title: Deep Learning as an alternative to downward continuation filters for structural interpretation
Speaker: Jean-Philippe Paiement, P.Geo., M.Sc. – Director, Global Consulting - Mira Geoscience
Abstract: Oftentimes when working with regional magnetic surveys from multiple sources, we encounter resolution continuity issues, which makes 2D interpretation more challenging. The loss in resolution of anomalies borders and lack of texture in the gridded data, can cause issues to the interpreter. This talk sets the basis of using currently available deep learning architecture to train a model for special resolution enhancement.
Recent advancement in image processing and deep learning have led to the development of neural networks capable of increasing images resolution using and adversarial learning strategy (Wang, X et al., 2018). In this deep learning model, available high-resolution grids with their low-resolution counter parts are used to train an encoder-decoder network to reconstruct the high-resolution from their starting point. Once the network is sufficiently trained it is then possible to apply it to upscale low-resolution images without existing ground truth high resolution counter part. This approach uses Generative Adversarial Networks or GAN’s, a relatively new class of machine learning frameworks designed in 2014 (Goodfellow, I. et al). A generator network is used to construct images that are then passed through a discriminator network which tries to discriminate between real images and fake images produced by the generator. Given a training set, this technique learns to generate higher resolution data with the same statistics as the training set.
Once the general model is trained on high-resolution/low-resolution pairs, it is possible to refine it to the area of interest and use it to upscale low resolution survey patches. This will help in refining anomaly edges and increase the accuracy of the structural interpretation conducted by the geologist. This approach is proposed as an alternative to the commonly used downward continuation filters used in the industry.
Biography: Jean-Philippe Paiement is the Director of Global Consulting at Mira Geoscience Ltd. He brings 15 years of mineral exploration experience to the table, including expertise in geostatistics applied to structural, geological, and geochemical modelling and interpretation; specializing in non-linear interpolation and simulation. Jean-Philippe has developed multiple workflow and novel approaches to reduce interpretational risks of geological data. Jean-Philippe has a wide range of experience in mineral resource estimation for precious metals, base metals and industrial minerals across diverse geological environments around the world. In 2016, Jean-Philippe has pioneered the application of Machine Learning to the mineral exploration industry in winning the Integra GoldRush challenge by application of machine learning to mineral deposit targeting. He is skilled in the application of machine learning to overcome geological and geophysical challenges; by combining geological knowledge and both supervised learning and deep learning. Before joining Mira Geoscience, he obtained an MSc from Laval University. Jean-Philippe is based in Quebec-City.

Modular course on Exploration Geophysics
Every second December, The Mineral Exploration Research Centre at Laurentian University presents a modular course on Exploration Geophysics. This year the course will be held December 8-17 in the Executive Learning Centre, room FA-386 of the Fraser building on Laurentian’s Sudbury campus. The course can be taken by graduate students for credit towards their degree programs, or by professionals, in which case it can be counted towards the hours required for continuing education by professional registration organizations like the PGO. This year, professionals can sign up at a reduced rate if they participate in the lectures remotely and on-line.
The course is intended for geologists and geophysicists and will cover all aspects of geophysical methods: theory, instrumentation, acquisition, processing, display and interpretation. The methods covered and the case histories presented will be focused on mineral exploration.
More details about the course and links to a brochure and a registration form can be found here

French announcement:
KEGS-Québec : Réunion Virtuelle 5-à-7 Géophysique et Remise des Bourses de la Fondation KEGS
Date : 26-novembre, 2021 de 17h à 19h.
Cher(e)s collègues et ami(e)s géophysiciens et géophysiciennes québécois(es) et franco-canadien(ne)s,
L'année 2021 a été une autre année très différente pour nous tous, mais heureusement les choses reviennent petit-à-petit à la normale.
À défaut de se rencontrer encore une fois cette année au déjeuner du KEGS-Québec ou dans le cadre d'un autre congrès, nous vous invitons à vous joindre à nouveau à un 6@7 Virtuel Géophysique.
En même temps, nous ferons la remise des Bourses de la Fondation KEGS aux récipiendaires universitaires québécois pour l’année 2021.
Ce sera une belle occasion de se voir le moment de conférences, de célébrer la future relève étudiante et de faire une petite santé de fin d'année, tous ensembles.
Cette année nous avons deux conférenciers : Pour débuter, M. Adrien Dimech, candidat au doctorat de l’UQAT, et le récipiendaire inaugural de la Bourse des Pionniers de la Géophysique Québécoise, nous fera une courte présentation sur sa recherche doctorale.
Ensuite, notre conférencier principal sera M. Marc Boivin qui nous présentera sa conférence intitulée : « L’aimantation rémanente en exploration minérale».
Conférencier
Marc Boivin MB Géosolutions
Titre
L’aimantation rémanente en exploration minérale
Sommaire :
Le phénomène de l’aimantation rémanente est connu depuis très longtemps, mais a souvent été considéré comme marginal du point de vus de l’exploration minière. Cependant, plusieurs gisements métallifères sont directement associés à réponses d’aimantation rémanente.Des liens directs peuvent être faits entre l’aimantation rémanente la mise en place de certains types de gisement métallifère et pourraient même servir d’outil en exploration minière. Cette présentation fait un survol rapide de ce concept à partir de réflexions personnelles et d’exemples..
Biographie :
L’auteur, M. Marc Boivin est géophysicien consultant avec MB Géosolutions depuis 2006. Il a travaillé comme chef géophysicien pour SOQUEM entre 1993 et 2006, géophysicien d’exploration pour WMC entre 1990 et 1993 et géophysicien de terrain pour Sagax Géophysique entre 1985 et 1990.M. Boivin a étudié aux études supérieures à l’École Polytechnique de Montréal en géophysique entre 1984 et 1985, après avoir complété un B.Sc. en géologie à UQAM en 1983. Il est membre de l’OGQ, PGO et APEGNB.
Par la suite, comme l’année passée, nous espérons que vous pourrez rester en-ligne pour une réunion (virtuelle) entre amis(es).
Joignez-vous à nous le 26 novembre prochain de 17h à 19h ET. Le lien ci-dessous vous mènera vers la visio-conférence (ajoutez le à vos calendriers):
