在我国贵州某低中温热卤水改造层控铀－汞矿床和湖南某古岩溶热造铀矿床中几乎同时发现了新矿物─—硒锑矿（Ｓｂ＿２Ｓｅ＿３）．该矿物的单晶呈细板条状、针状，集合体呈放射状、禾束状。确定硒锑矿形成于１３０─１６０℃富含Ｃａ￣（２＋），Ｎａ￣＋，Ｍｇ￣（２＋），ＳＯ＿４￣２－，ＨＣＯ＿３￣－的弱酸性─弱碱性热液，伴生一套典型的低中温热液矿物组合和围岩蚀变。硒锑矿是低中温热液标型矿物 A new mineral, selenium and stibnite (Sb 2 Se 3), has been found almost simultaneously in an uranium-mercury deposit in a low-medium-temperature transitional brine mine in Guizhou, China, and in an ancient karat-forming uranium deposit in Hunan. The mineral crystal fine strip, needle, aggregate radial, Wo beam shape. It is confirmed that the selenium and stibnite is formed in a weakly alkaline-weak alkaline hydrothermal solution rich in Ca ~ (2 +), Na ~ +, Mg ~ (2 +), SO_4 ~ 2-, and HCO_3 ~ Low and medium temperature hydrothermal mineral assemblages and wall rock alteration. Selenium antimony ore is low to medium temperature hot liquid standard mineral
