Large Igneous Provinces (LIPs) are huge volume, short duration volcanic/intrusive events that occur every 20-30 million years and rival plate tectonics in importance. LIPs have become an important research focus because they help reveal the configuration of ancient (Pre-Pangea) supercontinents, provide insights into volcanism on other planets, caused dramatic climate change including mass extinctions throughout Earth history, and are growing in importance as a tool for finding new ore and also oil/gas deposits.This new LIP project promises our Industry Partners a dramatic expansion of the LIPs record with application to resource exploration for a wide range of commodity types: from igneous hosted Ni-Cu-PGE districts, gold hosted orogenic belts and sedimentary basins that host uranium, base metals, gold and petroleum. This new 2018-2022 LIPs Project builds on our 2010-2015 and 2016-2017 Industry-supported projects, and comprises 5 themes: paleomagnetism, geochemistry, U-Pb geochronology, geospatial data consolidation and data processing and LIP architecture.This research will benefit Canadian companies because resource exploration is a global effort, and targeting insights developed in any region using the LIP record can have wide applicability elsewhere, including within Canada. Also, in ancient supercontinents the distribution of crustal regions was much different than at present.So an important prospecting tool is to trace important ore deposits into other crustal blocks that were formerly adjacent. Canada hosts many of the largest crustal blocks, and so many ore deposit bearing belts can potentially be traced into Canada from formerly adjacent regions.

大型火成岩省(LIP)是指体积巨大、持续时间短的火山/侵入事件，每隔2000-3000万年发生一次，在重要性上与板块构造相竞争。LIPS已成为一个重要的研究焦点，因为它们有助于揭示古代(前盘古)超大陆的形态，提供对其他星球上火山活动的洞察，导致包括整个地球历史上的大规模灭绝在内的戏剧性气候变化，并且作为发现新的矿石和石油/天然气矿床的工具正变得越来越重要。这个新的LIP项目向我们的行业合作伙伴承诺，LIPS记录将显著扩展，应用于广泛的商品类型的资源勘探：从火成岩赋存的镍-铜-铂族元素区，赋存金矿的造山带和蕴藏铀、贱金属、金和石油的沉积盆地。这一新的2018-2022年LIPS项目建立在我们2010-2015年和2016-2017年行业支持项目的基础上，包括5个主题：古地磁、地球化学、U-Pb地质年代学、地理空间数据整合、数据处理和LIP架构。这项研究将使加拿大公司受益，因为资源勘探是一项全球努力，目标是利用LIP记录在任何地区开发的洞察力，可以在其他地方广泛适用，包括在加拿大境内。此外，在古代超大陆中，地壳区域的分布与现在有很大的不同。因此，一个重要的找矿工具是将重要的矿床追踪到以前相邻的其他地壳块体中。加拿大拥有许多最大的地壳区块，因此许多矿床承载带可能从以前相邻的地区追踪到加拿大。
