1892 G. A. Koenig in Proc. Acad. Nat. Sci. Philadelphia 1891 289 The tetragonal crystals are so unique in their appearance, that they should be accorded the rank of a very distinct species, and the name Paramelaconite is proposed for them.
1941 Amer. Mineralogist 26 659 The paramelaconite occurs as stout prismatic crystals up to 3 cm. in length.
1996 Jrnl. Solid State Chem. 121 33/1 The unequivocal synthesis of Cu4O3 (paramelaconite) is reported for the first time.
