Marklite is a hydrated copper carbonate mineral named after Gregor Markl, a German mineralogist at the University of Tübingen.{{Cite web|url=http://mineralchallenge.net/new-mineral-listing/#Marklite|title=New Mineral Listing {{!}} Carbon Mineral Challenge|website=mineralchallenge.net|language=en-US|access-date=2017-09-04|archive-url=https://web.archive.org/web/20170905053051/http://mineralchallenge.net/new-mineral-listing/#Marklite|archive-date=2017-09-05|url-status=dead}} Markl found the type specimen of marklite in the dumps of the Friedrich-Christian mine in the Black Forest Mountains in southwestern Germany.{{Cite web|url=http://mineralchallenge.net/carbon-mineral-challenge-update-spring-2016-four-new-minerals-found/|title=Carbon Mineral Challenge Update Spring 2016: Four New Minerals Found {{!}} Carbon Mineral Challenge|website=mineralchallenge.net|language=en-US|access-date=2017-09-04}} Markl specializes in crustal petrology and geochemistry and has studied the hydrothermal ore deposits of the Black Forest area.{{Cite web|url=https://www.mindat.org/min-46877.html|title=Marklite: Marklite mineral information and data.|website=www.mindat.org|access-date=2017-09-04}} Jakub Plášil of the Institute of Physics at the Academy of Sciences of the Czech Republic and colleagues identified its structure.{{Cite web|url=http://www.jachymov2016.cz/abstracts|title=New Minerals and Mineralogy of the 21st Century International Scientific Symposium Jachymov 2016}}

Marklite crystals are long, thin blades that reach 0.2 mm in length. The mineral is chemically similar to georgeite, claraite, cuproartinite, azurite, and malachite.
