Igneous and volcanic rocks play a central role in the make up of Canada's varied geology. Magmatic activity in the form of volcanism, emplacement of magma into the Earth's crust and associated interaction between hot fluids and these rocks, play a key role in the formation of many varied and economically important mineral deposits, that help fund the nation's economy. At the same time, the presence of volcanoes close to large cities, such as Vancouver, pose concerns in terms of potential natural hazards. The study of igneous rocks and activity, therefore, is crucial in not only helping understand, identify and model the geological processes inherent in the generation of gold and other mineral deposits, but additionally and perhaps more significant in characterising cycles of volcanic activity and their estimated timeframes of operation. This type of information can help in the prediction of volcanic eruptions. To this background, this research program will study igneous rocks and the products of volcanism from parts of western Canada, Italy, and Colombia, to describe their nature and origins, and model the development of magmas. It will utilise state-of-the-art analytical equipment in combination with field and laboratory investigations. This project provides excellent training opportunities for 1 Ph.D. and 2 M.Sc.-level students in addition to supporting several undergraduate student research projects. As such, it will train the highly qualified people needed to keep Canada at the forefront of Geoscience education, exploration and research.

火成岩和火山岩在构成加拿大多样的地质中起着中心作用。火山活动形式的岩浆活动，岩浆进入地壳，以及热流体与这些岩石之间的相关相互作用，在许多不同的、具有重要经济意义的矿藏的形成中起着关键作用，这些矿藏为国家的经济提供资金。与此同时，火山靠近大城市，如温哥华，在潜在的自然灾害方面引起了人们的关注。因此，对火成岩和活动的研究至关重要，不仅有助于理解、确定和模拟金矿和其他矿藏产生所固有的地质过程，而且在描述火山活动周期及其估计的活动时间范围方面可能更为重要。这类信息有助于预测火山爆发。在此背景下，本研究项目将研究加拿大西部、意大利和哥伦比亚部分地区的火成岩和火山作用产物，描述它们的性质和起源，并模拟岩浆的发展。它将利用最先进的分析设备，结合现场和实验室调查。该项目为1名博士和2名硕士研究生提供了良好的培训机会，并支持了几个本科生的研究项目。因此，它将培养高素质的人才，使加拿大保持在地球科学教育、勘探和研究的前沿。
