The exceptionally rich and variable mineral associations, and the high number of mineral species, make this area one of the most remarkable mineralogical localities on a worldwide scale. The present paper reviews the data on geological setting of the ore district, individual ore deposits and mining history. Horní Slavkov and Krásno were known as a rich source of exquisite quality mineral specimens stored in numerous museum collections throughout Europe. The old museum specimens are often known under the German locality names of Schlaggenwald (= Horní Slavkov) and Schönfeld (=Krásno). The megascopic properties and paragenetic position of selected mineral classics are reviewed which include arsenopyrite, fluorapatite, fluorite, hübnerite, chalcopyrite, carpholite, cassiterite, quartz, molybdenite, rhodochrosite, sphalerite, topaz and scheelite. Key words: Sn-W ores; tin-tungsten mineralization; mining history; ore geology; mineralogy; Slavkovský les; Krásno, Horní Slavkov ore district; Czech Republic.

    A Mossbauer Effect Study of Triplite and Related

    Anerican Mineralogist Vol. 57, pp. 1109-7114 (7972) A MOSSBAUEREFFECT STUDY OF TRIPLITE AND RELATED MINERALS EowennKosttnon,l Baher Laboratorg of ChemistryCornellUniuersitg Ithaca,New Yorlt14850 Arsrnaqr Mdssbauer parameters are reported for the phosphate minerals triplite, zwieselite, triploidite, and wolfeite. Analysis of the absorption data confirms the existence of non-equivalent ferrous ions. The broadening of the resonance peaks is rationalized on the basis of a microscopic disorder due to half-occupied fluorine sites in the fluoride minerals and to sets of closelv related metal sites in the hydroxy minerals. INrnonucrroN Recently the crystal structures of triplite (Waldrop, 1969) and triploidite (Waldrop,1970), two relatedphosphate minerals, have been determined.This paperreports the 5?FeMijssbauer effect spectroscopy of triplite and three relatedminerals-swieselite, wolfeiter, and triploi- dite. ExppntlrnNrar, The mineral samples were generously zupplied by L. Waldrop. A description of each follows. Triplite-(Mn,Ie)"PO.F, from Mica Lode pegmatite, Eight Mile Park, Fre- mont County, Colorado, Mno *Feo TCao1PO4F. Composition and "-Mgo mineralogy described by, Heinrich (1951). The crystal structure is mono- clinic with two equally populated metal sites M(1) and M(2), each octahedrally coordinated by four oxygen and two fluorine atoms. The occupancy of the two metal sites is (Waldrop, 1969) M(l): 0.717Mn, Fe + 0.231Mg f 0.052Ca M(2):0.a$ Mn, Fe + 0.469Mg * 0.048Ca Zwieselite-(Fe,Mn)fOnF, from Zwiesel,Bavaria. Describedin Palache et aI. (1944),p.851. The atomic ratio of iron to manganeseis 2.00; trace amounts of calcium and magnesium are present. Precession photographs show these specimensto be isotypic with triplite (Waldrop, 1970).
