Exploration for mineral deposits is becoming increasingly challenging as the industry shifts away from identifying shallow mineralized intrusions to identifying deep-seated intrusions. The success of mineral exploration, therefore, depends on the development of robust mineral deposit models and geochemical exploration tools. Development of such exploration criteria for magmatic Ni–Cu–PGE deposits has been challenging as these systems develop and are modified by a complex set of magmatic and post-magmatic processes. Using the Cu–PGE-mineralized Eastern Gabbro of the Coldwell Complex, Ontario, Canada as an example, we will explore the petrogenesis of the
host rocks and the processes that generated and modified the conduit-type mineralization using Fe–Ti oxide and base-metal sulfide chemistry, and assess the applicability of Fe–Ti oxide and late stage vein mineral chemistry to identifying and vectoring towards mineralization. This presentation will highlight the complexity of conduit-type Ni–Cu–PGE systems that arise from the combination of primary magmatic and late-stage hydrothermal processes, the challenges associated with the development of robust exploration tools, and the need to integrate detailed textural analysis with high-resolution mineral chemistry in the assessment of mineral deposit petrogenesis.

"A fundamental role of carbonate–sulfate melts in the formation of iron oxide–apatite (IOA) deposits"

Kiruna-type iron oxide-apatite (IOA) deposits are an enigmatic class of magnetite-rich systems with a wide range of proposed genetic models. Here I present the results of three studies which examine inclusions in ore-stage apatite, diopside, and magnetite from characteristic IOA systems. These studies show that IOA mineralization in all three systems is associated with unusual Fe-rich, carbonate-sulfate melts which show remarkable consistency in terms of their compositions and microthermometric behavior. Moreover, carbon (δ13C) and oxygen (δ18O) isotope data indicates that these melts were formed via the anatexis and/or assimilation of local evaporite-bearing sedimentary rock by mafic-intermediate magmas in these systems. This interpretation is supported by the common occurrence of mafic-intermediate intrusive rocks crosscutting and assimilating evaporite-bearing carbonate strata in many notable IOA localities. These results indicate that a previously unrecognized genetic process involving crustal anataxis is involved in the formation of IOA mineralization and perhaps also promotes the formation of other Fe-, Ti-, and REE-rich systems.

The Ontario Geological Survey (OGS) is a provincial government organization responsible for the collection, interpretation, documentation and dissemination of public geoscience data and information. We provide accessible data through maps, reports, data releases and models.

The purpose of this session is to provide information about the OGS (Who are we? What do we do? How do we do it? Why do we do it?), to explain how to access publicly available geoscience data, and to provide students with an opportunity to meet some of our geoscientists. This presentation will outline the various sub-disciplines of geoscience that the Earth Resources and Geoscience Mapping Section of the OGS undertakes.

The OGS provides geoscience-related employment opportunities for students before and after graduation. Students have an opportunity to work and learn with internationally recognized geoscientists. Within the context of the pandemic and evolving work restrictions, positions may be field and/or office based.

Abstract:
Tectonic plates slide past one another along faults and shear zones through a mixture of brittle fracture, frictional sliding, and ductile flow. These faults and shear zones host the world’s largest earthquakes, are zones of enhanced permeability and fluid flow through the crust, and serve as traps for mineral, water, and hydrocarbon resources. There are many ways rocks and minerals can deform. At shallow crustal levels minerals fracture and slide frictionally past one another, while at greater depths minerals deform internally by reorganizing imperfections and diffusing elements through the crystal lattice. In this presentation, I will show how micro-scale observations of grain-scale deformation elucidate the mechanics of rock deformation and inform geodynamic models of tectonic processes.

BIO:  Dr. Noah John Phillips is a structural geologist who studies how rocks and minerals deform from the field- to nano-scale to better understand the movement of tectonic plates, the earthquake cycle, and the structural controls of mineral, water, and hydrocarbon resources. Noah completed his PhD at McGill University in 2019, his MSc at the University of New Brunswick in 2015, and his BSc at the University of British Columbia in 2012. He is currently a Postdoctoral Research Fellow at Texas A&M University where he develops free applications and databases for field, microstructural, and experimental observations as part of his research (the StraboSpot initiative).
