APAKAH MAKSUD TETRAHEDRITE dalam CORSICA?
Tetrahedrite
Tetrahedrite adalah mineral antimon sulfosalt tembaga dengan formula: 12Sb4S13. Ini adalah akhir antimoni siri penyelesaian pepejal yang berterusan dengan tennantit galas arsenik. Penghujung tulen dari siri ini jarang sekali dilihat dalam alam semula jadi. Daripada keduanya, fasa kaya antimon lebih umum. Unsur-unsur lain juga menggantikan struktur, terutamanya besi dan zink bersama dengan perak, merkuri dan plumbum yang kurang biasa. Bismuth juga menggantikan tapak antimon dan tetrahedrite bismuthian atau annivite adalah pelbagai yang diiktiraf. Yang berkaitan, perak yang dominan, spesis mineral freibergite, walaupun jarang, terkenal kerana ia boleh mengandungi sehingga 18% perak. Kristal Tetrahedrite dengan kalkopirit dan sphalerite dari Lombong Casapalca, Peru Tetrahedrite mendapat namanya dari tetrahedron tersendiri yang berbentuk hablur kubik. Mineral biasanya berlaku dalam bentuk besar-besaran, ia adalah kelabu keluli kepada mineral metalik hitam dengan kekerasan Mohs 3.5 hingga 4 dan graviti khusus 4.6 hingga 5.2. Ia berlaku dalam urat hidroterma suhu yang rendah hingga sederhana dan dalam beberapa deposit metamorf yang bersentuhan. Ia adalah bijih kecil tembaga dan logam yang berkaitan.
Definisi tetrahedrite dalam kamus Corsica
Takrif tetrahedrite dalam kamus adalah mineral logam abu-abu yang terdiri daripada sulfida tembaga, besi, dan antimoni, sering dalam bentuk kristal tetrahedral: ia adalah sumber tembaga. Formula: 12Sb4S13.

The Stability of Minerals
This assumption may be justified on the basis that the Ag-Cu exchange reaction
of interest is the sum of this reaction and the Ag-Cu exchange reaction between
tetrahedrite and metal, Ag + i^Cu1oFe2Sb4S13 = i1oAg1oFe2Sb4S13 + Cu.
