I had the pleasure of spending my summer of 2025 in Johannesburg, where I completed a research internship at the University of Johannesburg (UJ), focused on geochronology in an unusual area near the small town of Balfour.<\/p>\n\n\n\n<p>The area is sometimes referred to as <em>\u201cThe Vaalrand Enigma\u201d,<\/em> since its geological context has long been uncertain. To help solve this puzzle, my supervisors, Marlina Elbourg and Michiel de Kock, set out to date the rocks from a hillside known as Vaalrand. Determining their age would allow us to understand what these rocks correspond to and whether they fit within the local Witwatersrand Supergroup.<\/p>\n\n\n\n<p>When we first arrived in Johannesburg, we joined a field trip with the third-year students at UJ. The course focused on geological mapping in the province of KwaZulu-Natal, close to South Africa\u2019s east coast near Durban. Each day, we headed out into the field with the student groups, helping with mapping while exploring some of the region\u2019s fascinating geology.<\/p>\n\n\n\n<p>Even though it was mid-winter, the midday heat was a welcome change from the colder climate back in Johannesburg at this time of year. The trip was also a chance to connect with the South African students, share experiences, and learn more about their culture and studies at UJ. It was a rewarding week, filled with long hikes in the African bush, new friendships, and plenty of learning.<\/p>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-723ac29e\" class=\"wp-block-themeisle-blocks-advanced-columns has-2-columns has-desktop-equal-layout has-tablet-equal-layout has-mobile-collapsedRows-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-93b9f23c\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"704\" height=\"939\" data-src=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils2.png\" alt=\"\" class=\"wp-image-1502 lazyload\" data-srcset=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils2.png 704w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils2-225x300.png 225w\" data-sizes=\"(max-width: 704px) 100vw, 704px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 704px; --smush-placeholder-aspect-ratio: 704\/939;\" \/><\/figure>\n<\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-column-04a755d5\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"704\" height=\"939\" data-src=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils3.png\" alt=\"\" class=\"wp-image-1503 lazyload\" data-srcset=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils3.png 704w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils3-225x300.png 225w\" data-sizes=\"(max-width: 704px) 100vw, 704px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 704px; --smush-placeholder-aspect-ratio: 704\/939;\" \/><\/figure>\n<\/div>\n<\/div><\/div>\n\n\n\n<p>&nbsp;Once we returned to Johannesburg, we launched into work on Vaalrand, devoting the next two days to collecting samples and getting familiar with the rocks. It was both fun and educational, marking the beginning of a long process.<\/p>\n\n\n\n<p>After that, my daily routine varied a lot as I worked on preparing the rocks for uranium-lead dating. The procedure can be long and tedious, and it\u2019s what I spent most of my time in Johannesburg doing. The samples first had to be crushed and milled, then gold panned to separate the heavier minerals. From there, I examined the heavy fraction grain by grain, searching for zircon, the tiny crystals we needed to measure their chemical composition. Everything had to be done carefully to avoid contamination.<\/p>\n\n\n\n<p>Patience is essential in this kind of work, given how time-consuming it can be. When I finally saw my very first age appear on the computer, the long hours melted away, replaced by sheer ecstasy. In that moment, it felt as though every effort had paid off.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" data-src=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1-1024x1024.png\" alt=\"\" class=\"wp-image-1505 lazyload\" data-srcset=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1-1024x1024.png 1024w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1-300x300.png 300w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1-150x150.png 150w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1-768x768.png 768w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils4-1.png 1332w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/1024;\" \/><\/figure>\n\n\n\n<p>Beyond the lab and my work at UJ, we also had time to experience Johannesburg and see what South Africa has to offer. We tried out great restaurants, explored clubs, and found cozy caf\u00e9s perfect for Sunday coffee. One of the highlights was going on safari in Pilanesberg National Reserve, an unforgettable chance to see wildlife up close.<\/p>\n\n\n\n<p>Johannesburg often has a reputation for being dangerous, both internationally and among South Africans themselves, but we had a positive experience. The risks are real, of course, yet with some basic precautions, it\u2019s possible to enjoy the city safely. The best advice is to listen to locals, avoid sketchy areas, and don\u2019t walk around with your phone out, as it might get snatched. Ubers are reliable and affordable, and they make it easy to get around securely, which is important in a city as large as Johannesburg.<\/p>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-f8f15fe9\" class=\"wp-block-themeisle-blocks-advanced-columns has-2-columns has-desktop-equal-layout has-tablet-equal-layout has-mobile-collapsedRows-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-ffc94c5b\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"760\" height=\"1014\" data-src=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils5.png\" alt=\"\" class=\"wp-image-1507 lazyload\" data-srcset=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils5.png 760w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils5-225x300.png 225w\" data-sizes=\"(max-width: 760px) 100vw, 760px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 760px; --smush-placeholder-aspect-ratio: 760\/1014;\" \/><\/figure>\n<\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-column-e021fa92\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"760\" height=\"1014\" data-src=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils6.png\" alt=\"\" class=\"wp-image-1508 lazyload\" data-srcset=\"https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils6.png 760w, https:\/\/site.uit.no\/realfagspraksis\/wp-content\/uploads\/sites\/523\/2025\/09\/Nils6-225x300.png 225w\" data-sizes=\"(max-width: 760px) 100vw, 760px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 760px; --smush-placeholder-aspect-ratio: 760\/1014;\" \/><\/figure>\n<\/div>\n<\/div><\/div>\n\n\n\n<p>What surprised me most was the large number of trees woven through the city. Johannesburg is said to be one of the largest urban forests in the world, with trees lining nearly every street. I was there in winter, but everyone told me that in summer the city turns purple when the jacarandas bloom, something I\u2019d love to come back and see one day.<\/p>\n\n\n\n<p>This internship has challenged my knowledge of geology and given me some important work and life experiences that I will cherish for the rest of my life.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp;Hello, my name is Nils Henrik, and I\u2019ve just finished my bachelor&#8217;s degree in geoscience.
