“…Al though many hy dro ther mal REE de pos its are as sumed to form from flu o ride com plexes, ex tremely low sol u bil ity of REE-flu o rides in low-tem per a ture solu tions may in di cate that pos si ble con tri bu tion of flu o ride species to REE trans port is much less sig nif i cant (Migdisov et al, 2016). The other ob vi ous can di dates for trans port ing REE are sulphates (Sholkovitz, 1995;Gieré, 1996;Johannesson et al, 1996;Wood, 2003;Migdisov et al, 2016).…”

“…There is plenty of ev i dence that low-pH so lu tions rich in sulphates are more ca pa ble of be ing en riched in MREE through sul phate complexation be cause MREE sul phate lig ands are most sta ble com pared with LREE and HREE equiv a lents, in dicat ing greater MREE mo bil ity (Johannesson et al, 1996;Gammons et al, 2003;Zhao et al, 2007). It was clearly dem onstrated (e.g., Bau, 1999;Worrall and Pearson, 2001;Protano and Riccobono, 2002;Verplanck et al, 2004;Olias et al, 2005;Welch et al, 2009;Ma et al, 2011) that metal sul phide-con taining rocks af fected by acidic wash ing tend to be de pleted in MREE whereas flu ids re sult ing from ox i da tive al ter ation pres ent MREE-en riched sig na tures and that fer ric oxyhydroxides played a cru cial role in both the REE up take and re moval.…”

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.

Mineralogy and geochemistry of Permian–Triassic lateritic‐bauxitic horizons, eastern and central Alborz, Iran: Implications for provenance, palaeogeography, and palaeoclimate

et al. 2022

This paper presents a survey of geological attributes on the lateritic‐bauxitic deposits to examine their provenance, palaeogeography, and palaeoclimate condition in the Permian–Triassic boundary of Alborz Mountain, north Iran. The mineralogical analysis revealed that haematite, quartz, goethite, kaolinite, diaspore, boehmite, and anatase are the major rock‐forming minerals in these deposits. The major oxide composition of samples detected that enrichment of Al2O3 (up to 31.5%) and Fe2O3 (up to 37.9%) led to the formation of laterite, kaolinitic laterite, and bauxitic kaolinite. The distribution of trace and rare elements provides information about the enrichment of deposits concerning immobile elements. Employing geochemical proxies such as Al2O3/TiO2, bivariate diagrams of Eu/Eu* versus Sm/Nd and TiO2/Al2O3, enrichment of samples relative to heavy rare earth elements, and positive Eu anomaly revealed that the deposits originated from intermediate to mafic rocks. Several factors are inferred to be responsible for the transformation of parent rock(s) into lateritic‐bauxitic deposits: The high values of CIA, CIW, and PIA (mostly above 80) and increase of kaolinite point to deep to moderate parent rock(s) weathering, which is consistent with warming and humidity around the Permian–Triassic boundary. In continuation, transportation and trapping of weathered materials above the karstified carbonate bedrock of the Ruteh Formation and environmental interactions induced the formation of new minerals in a transitional environment near the vadose zone. The deposits have a generic correspondence with Palaeotethys Oceanic crustal subduction due to tectonic uplift, exhumation of bedrock, and regional sea‐level fall at the end of Palaeozoic that offered an opportunity for lateritization process.
