About Veenite
Formula:
Pb16Sb9-xAs7+xS40, x ~ 0-0.5
As is essential, Ag is not.
Bulk composition of SXRD-analysed sample (Topa & Makovicky, 2017) is: Ag0.15Pb16.029Sb8.836As6.99S39.95.

Name:
Named after Rudolf Willem van der Veen (27 January 1883, Buitenzorg (now Bogor), Dutch East Indies (now Indonesia) — 3 April 1925, Wassenaar (near The Hague), South Holland, The Netherlands), metallographer, mining engineer. After his studies in Delft he worked in mines in Argentina, Bolivia, India, Germany, and Spain. From 1916 to 1925 he was professor of economic geology at the Delft University of Technology (Netherlands). In 1925, he posthumously published one of the first books with pictures about ore microscopy.
Dufrénoysite-Veenite Series.
Sartorite homologue, N = 4; the structure is based on zigzag walls of prismatic [3]Pb; these walls separate slabs comprising diagonally-oriented double layers containing Sb and As, and some Pb. Orientation of three-membered crankshaft chains containing (As,Sb)–S is substantially different from that in dufrénoysite.

Other Information
Notes:
KOH (40%) tarnishes veenite iridescent and HNO3 tarnishes it black. KOH generally brings out the polysynthetic twinning also evident under partly crossed nicols.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
