'''الماسوييت''' (Masuyite) عبارة عن [[معدن]] [[أكسيد]] ال[[يورانيوم]]/ال[[رصاص]] [[صيغة كيميائية|صيغته]] Pb[(UO<sub>2</sub>)<sub>3</sub>O<sub>3</sub>(OH)<sub>2</sub>]·3H<sub>2</sub>O .<ref name=Webmineral>http://www.webmineral.com/data/Masuyite.shtml Webmineral {{Webarchive|url=https://web.archive.org/web/20230603081214/https://webmineral.com/data/Masuyite.shtml|date=2023-06-03}}</ref>

وُصف ظهور الماسوييت لأول مرة في عام 1947 م في [[محافظة كاتانغا|كاتانغا]] وسمّي باسم عالم ال[[جيولوجيا]] ال[[بلجيكا|بلجيكي]] [[جوستاف ماسوي]] تكريماً له (1905-1945) .<ref name=handbook>http://rruff.geo.arizona.edu/doclib/hom/masuyite.pdf Handbook of Mineralogy {{Webarchive|url=https://web.archive.org/web/20230324160748/http://rruff.geo.arizona.edu/doclib/hom/masuyite.pdf|date=2023-03-24}}</ref>
