The beauty of this mountainous region is the product of a long and complex geological evolution, spanning 800 million years of Earth's history. This complex geological evolution featured the formation and break up of multiple supercontinents, continental collisions and uplift of Himalayan scale mountain ranges, formation of active volcanoes, continental drift from high southern latitudes to mid northern latitudes and finally sculpting of the mountain peaks and glens by Arctic ice sheets and glaciers during the most recent Ice Age.

They are the source of most diamonds and bring us direct sampling of Earth’s mantle (otherwise only available indirectly by geophysical methods). They are confined to the ancient cratons of the continents: the oldest and thickest parts of the continental crust (where the geothermal gradient is low) and are now known to occur on all the continents. They were not formed in the earliest phases of Earth’s history. Emplaced explosively in carrot-shaped pipes, they are pyroclastic rocks close to the surface (often removed by erosion) but become hypabyssal (dykes and sills) at depth. Kimberlites belong to the ultramafic group of rocks with high MgO. They are consequently rich in olivine and lack feldspar. They are rich in volatiles, such as water and carbonate, and the above-mentioned mantle xenoliths and megacrysts, including eclogite, harzburgite, olivine, mica, zircon, diamond and others, as well as crustal xenoliths. Kimberlites are thus hybrid rocks and the nature of the parent magmas is difficult to define. Related rocks, which may contain diamonds, are lamproites and ultramafic lamprophyres. A recent article by Tony Waltham in <i>Geology Today</i> discussed kimberlites and especially their diamonds; here we concentrate on kimberlites themselves with lesser emphasis on other diamondiferous rocks.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"42 1","pages":"47-55"},"PeriodicalIF":0.0,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146680548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, primary ore deposits are finite, and to continue production, lower grade and more complex ore deposits need to be discovered, evaluated and exploited, with increasing exploration and production costs. Additionally, there are significant geopolitical constraints on global resources for some critical raw materials and metals, along with ethical constraints of ‘off-shoring’ minerals supply to areas of the world with poor records in terms of legal mineral production, human rights violations, health and safety, and the long-term environmental impact of mining. Whilst it is unlikely at present to be able to fully meet supply needs, one source of metals for the future is through recycling of both domestic and industrial waste. Modern waste streams such as end-of-life lithium-ion batteries and electrical waste commonly contain significantly more metals than primary ore deposits before processing. However, these waste materials are complex, and through two case studies in this article, we focus on how methods commonly used in modern mining and mineral processing can be used to assist the processing and recovery of metals from waste. Perhaps it is time to reclassify waste as valuable resources for the future.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"42 1","pages":"15-26"},"PeriodicalIF":0.0,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gto.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147269026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
