In this overall scenario, remote sensing has<br \/>\nplayed a key role in providing geologic information. From regional information on<br \/>\ngeologic units and structures to ore vectoring (such as mineral mapping), various airborne<br \/>\nand spaceborne sensors have been used in mineral exploration activities in the<br \/>\npast three decades. They have been deployed in different regions of South America,<br \/>\ngoing from the arid lands of the Andean Cordillera and Patagonia, into the rainforests<br \/>\nof the Amazon.<br \/>\nThis paper focuses on two successful case histories in South America that illustrate<br \/>\nthe technological developments of remote sensing as an exploration tool and<br \/>\ntheir impacts on mineral exploration activities. The benefits of increasing the spectral<br \/>\nresolution are examined, as well as the introduction of new sensors operating in<br \/>\nsome of the still underexploited portions of the electromagnetic spectrum and their<br \/>\nintegration with geophysical data. These techniques comprise the use of Landsat and<br \/>\nASTER to map hydrothermal alteration mineral associated with gold in Patagonia,<br \/>\nas well as SAR integrated with airborne geophysics for gold exploration in the<br \/>\nBrazilian Amazon.<br \/>\nFinally, some of the current and future technological trends are reviewed and<br \/>\ntheir impacts for mineral exploration activities in South America analyzed, including<br \/>\nthe deployment of multi-hyperspectral sensors in airplanes and satellites.<\/p>\n","protected":false},"featured_media":4695,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pmpro_default_level":""},"product_cat":[154],"product_tag":[],"_links":{"self":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product\/2421"}],"collection":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/comments?post=2421"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media\/4695"}],"wp:attachment":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media?parent=2421"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_cat?post=2421"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_tag?post=2421"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
