Giersdorf_00000829The Zadní Chodov uranium deposit was mined from 1952 to 1992 and was ranked among medium-size uranium deposits in the Bohemian Massif. The totalmine production of low-grade uranium ore (0.195 wt.% U) was 4151 t U. The deposit, which is located in the northern tectonic block of the Bor pluton, was investigated by mine workings down to levels of 1250m in a length of over 2.5 km. The contact with the Moldanubian high-grade metasediments is tectonic, comprising several parallel shear structures to the Zadní Chodov fault,which forms the western boundary of the Bor pluton. Migmatised biotite paragneisses of the Moldanubian Varied Group predominate and they contain intercalations of quartzites, amphibolites, calc-silicate rocks and crystalline limestones. Dykes and bodies of amphibole-biotite tonalites and biotite granites cut the paragneisses. Aplite, pegmatite and lamprophyre dykes occur but are less frequent and are particularly developed above and below large shear zones. Uranium mineralisation is associated with the N-S trending zones of the Zadní Chodov fault in areas of their intersection with NW-SE trending fault structures, which form a NW continuation of the Central fault. The Zadní Chodov shear zone has been verified in an extent exceeding 20 km, its thickness in the middle part reaches 500m, and the dip is 50–75° to the east. This dislocation passes northwards into the Eastern shear zone of the Zadní Chodov deposit. The infill of the shear zones consists of intensely altered and crushed rocks with chlorite-rich and/or clay-mineral-rich assemblages. Uranium mineralisation was concentrated into three shear zones
