Name:For Andor von Semsey (1833-1923), a Nobleman and amateur Hungarian mineralogist, whose first name gave rise to Andorite.


Plagionite Group

Semseyite belongs to a homologous series of lead antimony sulfides.The structure contains sheets of galena, the thickness of this sheet determines the position in the homologous series. Semseyite has the thickest sheet and Fülöppite the thinnest.
