“…Based on 32 sam ples from the Lubin-Sieroszowice dis trict, Michalik (2001) re ported the high est con cen tra tion of REE in the up per most Weissliegend, link ing this en rich ment with the pres ence of car bon ate ce ments, phos phates, flu o rides, and Fe-ox ide rims around de tri tal grains. Saw³owicz (1994Saw³owicz ( , 2013 achieved com pa ra ble re sults to those pre sented by Bechtel et al (2001b) by the study of rock sam ples from the Lubin-Sieroszowice dis trict (ICP-MS and INAA). This study dem on strates the over all REE bud get in differ ent re gions and seven REE di a grams for se lected sam ples of sand stones, shales and dolomites nor mal ized to the NASC stan dard.…”

“…2), and two sam ples from the Pomerania re gion in or der to de ter mine vari abil ity in REE con cen tra tion and dis tri bu tion with re spect to min er ali sation zones (Bechtel et al, 2001b Chondrite (McDonough and Sun, 1995), Up per Con ti nen tal Crust (Rudnick and Gao, 2003), World Shale Av er age (Piper, 1974), NASC -North Amer i can Shale Com pos ite (Gromet et al, 1984), PAAS -Post-Archean Aus tra lian Shale (McLennan, 1989), SDO-1 -Black Shales (Huyck, 1989), SDO-1 -Met al lif er ous Black Shales (Huyck, 1989) from the he ma tite, Cu, Zn-Pb, and py rite zones were ex am ined. The high est con tents of REE were found in ox i dized shales (in the range of 99 to 211 ppm, av er age 142 ppm), lower con centra tion in shales with Cu, Pb and Zn min er ali sa tion (69-96 ppm; av er age 83 ppm), and the low est con cen tra tion in py ritic shales (60-65 ppm; av er age 62 ppm).…”

“…Much less at ten tion has been paid to the re search of rare earth el e ments (REE). So far, mostly rock sam ples from the Lubin-Sieroszowice min ing dis trict have been stud ied (Janczyszyn et al, 1986;Mayer et al, 1992;Saw³owicz, 1994Saw³owicz, , 2013Bechtel et al, 2001b;Michalik, 2001). Ad di tional sam ples from only a few bore holes out side the min ing dis trict have been ana lysed (Mayer et al, 1992;Bechtel et al, 2001b).…”

Con trols on the dis tri bu tion of rare earth el e ments in the Kupferschiefer se ries of SW Po land. Geo log i cal Quar terly, 60 (4): 811-826, doi: 10.7306/gq.1325 This study deals with the spa tial dis tri bu tion and the PAAS-nor mal ized pat terns of rare earth el e ments (REE) stud ied by ICP-MS in the Kupferschiefer se ries of SW Po land. The most char ac ter is tic fea ture is a pro gres sive en rich ment in REE content (in clud ing Y and Sc) out ward from the rocks with py ritic and Pb-Zn min er al isa tion, across the rocks with cop per min er alisa tion, to wards the ox i dized (Rote Fäule) ar eas. The same trend can also be ob served with re spect to LREE, MREE and HREE. Whereas REE dis tri bu tion di a grams for shales with py rite and Pb-Zn min er al isa tion are al most flat, di a grams for shales with he ma tite and cop per min er al isa tion are con vex-up ward and the stron gest con vex ity is at trib uted to the tran si tion from hematitic al ter ation to cop per-rich rocks. REE dis tri bu tion di a grams nor mal ized to PAAS show strong MREE en richment rel a tive to LREE and HREE, which is typ i cally the high est in the he ma tite zone, lower in shale with cop per min er al isation, and the low est in shales with Pb-Zn and py rite min er al isa tion. The sys tem atic in crease in the con cen tra tion of REE to wards the Rote Fäule, and the strong en rich ment in MREE in the tran si tion zone are in dic a tive of vari able in ten sity of leaching and for ma tion of the REE en rich ments (in clud ing MREE) by MREE>HREE>LREE flu ids, as ev i denced by the MREE-enriched sig na tures. Over print ing of sec ond ary en rich ments over the orig i nal REE pat tern due to re dis tri bu tion along the path ways of ex pand ing flu ids are pos tu lated to ac count for the ap par ent dif fer ences in the dis tri bu tion and con cen tra tion of REE (in clud ing the MREE-en riched trend) be tween the ox i dized rocks, cop per-bear ing rocks, and re duced lithologies bar ren in cop per.
