More than just a scientific tool, this monumental document offers a panoramic view of Africa's underground structures, revealing landforms, rock formations, sedimentary areas, and tectonic faults with remarkable precision at a time when such data were still rare on the continent. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"915\" data-end=\"1484\"\u003eOn this map, each color shade tells a different geological story.

The use of hatching, subtle shades, and carefully calibrated symbols gives the document a visual elegance that far exceeds simple scientific use: it makes it a true piece of wall art. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"cartopolo","offers":[{"title":"30 x 40 cm \/ Creative paper 200 gsm","offer_id":52837455528279,"sku":null,"price":19.5,"currency_code":"EUR","in_stock":false},{"title":"50 x 70 cm \/ Creative paper 200 gsm","offer_id":52837455561047,"sku":null,"price":34.5,"currency_code":"EUR","in_stock":true},{"title":"70 x 100 cm \/ Creative paper 200 gsm","offer_id":52837455593815,"sku":null,"price":59.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/7854\/4418\/files\/GeologicalmapofSouthernAfrica198550x70affiche-papier-vintage-ancienne.jpg?v=1771585987","url":"https:\/\/cartopolo.fr\/en\/products\/carte-geologique-afrique-sub-saharienne","provider":"Cartopolo","version":"1.0","type":"link"}
