The black or black and white calcite spheres are systematically accompanied by needle-like sulfosalts which are known by the local miners as “plumosite”. The genesis of epithermal spheres composed partly or entirely of black calcite is considered to be related to the deposition of calcite within voids filled by hydrothermal fluids that contain acicular crystals of sulfosalts, mostly jamesonite in suspension. -

The objectives of the study were to: 17 identify whether these sulfosalts represent overlooked hosts for precious metals and other trace elements 18 of petrogenetic or economic interest; establish partitioning trends among co-existing sulfosalt species 19 and between sulfosalts and BMS; and to seek evidence for a genetic link between the abundance of (Cu)- 20 Pb-Sb sulfosalts and the high-fineness of native gold in the deposit. All (Cu)-Pb-Sb sulfosalts analyzed 21 were found to be remarkably poor hosts for gold and thus do not contribute to the overall mineralogical * Corresponding author E-mail address: [email protected] 1 22 balance for gold. -

New Lead Sulfantimonides from Madoc, Ontario
NEWLEAD SUTFANTIMONIDES FROM MADOC, ONTARIO. PART2_MINERAI DESCRIPTIONS J. L. JAMBOR Geol,ogical Survey of Canad,a, Ottawa AssrRAcr Itaunayite, playfairite, sterryite, twinnite, guettardite, and sorbyite are new lead sulfantimonides from Madoc,Cintario. An addiiionalsulfosalt, designated mineral eM, may be identical to coleman's (19b8)minerar e from yellowknifi, N.w.T. The-iew minerals are associatedwith boulangerite,jimesonite, antimonian baumhauerite (sb-:Aq: -1:1), zinckenite,semseyite, g"o".ottitu, robinsonite, and a few other sulfides andsulfosalts. IutnooucrroN In Part | (can. IvI'ineral.9, pt. 1, pp. z-24) the geological occurrence of the Madoc sulfosalts and the methods used to determine their com- positions were outlined, and two of the new minerals were described. Descriptions of the remainder of the new sulfosaltsr and tieir associated minerals are given in the present article. The concluding paper (part B) will consist of remarks on the paragenesis, possible mode of origin of the Madoc minerals, and brief notes on the synthesis of some pb-Sb-As sulfosalts. Opti,cal,Properti.es Data on polarization colours of the new [4adoc sulfosalts are lacking in the descriptions given below. The correct determination of this property is discussed by Bowie & Taylor (19b8), but the writer has unfortunately been unable to duplicate their data on known sulfosalts. The colours given in Part 1 for madocite and veenite will thus probably require revision. All the new sulfosalts described below have srrong anisotropism, but the citing of polarizationdata must be deferred. Leunavrre Launayite is named in honour of L. de Launay in recognition of his contributions in the nineteenth century concerning the origin of mineral deposits.
