单词 plenargyrite
释义

plenargyriten.

Brit. /plᵻˈnɑːdʒᵻrʌɪt/, U.S. /pləˈnɑrdʒəˌraɪt/
Origin: A borrowing from German. Etymon: German Plenargyrit.
Etymology: < German Plenargyrit ( F. Sandberger Untersuchungen über Erzgänge (1882) I. 96), apparently < classical Latin plēnus full (see pleni- comb. form) + ancient Greek ἄργυρος silver (see argyro- comb. form) + German -it -ite suffix1, after Miargyrit miargyrite n.Sandberger's reasoning behind his choice of the first element (assuming that it is indeed Latin plēn-) is unclear. Although the name seems to imply that the mineral has a higher silver content than miargyrite, AgSbS2, the proportion by weight of silver in plenargyrite is actually lower and Sandberger explicitly notes this as the motivation for his name.
Mineralogy. rare.
A mineral consisting of a sulphide of silver and bismuth, AgBiS2, that is a paramorph of matildite.
