Tululite, Ca14(Fe3+,Al)(Al,Zn,Fe3+,Si,P,Mn,Mg)15O36: a new Ca zincate-aluminate from combustion metamorphic marbles, central Jordan

Mineralogical Diversity of Ca2SiO4-Bearing Combustion Metamorphic Rocks in the Hatrurim Basin: Implications for Storage and Partitioning of Elements in Oil Shale Clinkering

“…Cd contents in the rocks are as low as 0.83 ppm, though phosphate layers have rather high enrichment in Cd (5-154 ppm) and in U [81]; some calcareous layers contain abundant baryte concretions [82]. The coeval Muwaqqar Fm sediments in central Jordan store high or extremely high concentrations of Zn, Cd, U, Ni, and V, due to a specific deposition environment [3,[6][7][8]78]. Table 4).…”

“…The Hatrurim larnite CM rocks contain accessory fine-grained Fe, Cu, K and Ca sulfides, Cu and Ag selenides, and Ca-Zr and Ca-U double oxides. The accessory mineralization is quite scarce unlike that of the Jordanian spurrite CM marbles which store rich and diverse sulfide/selenide (Zn, Cd, Ni, Mo, Ag) and/or oxide (Zn, Cd, U, Ni) accessories [3,[6][7][8].…”

“…A bright example comes from the coeval Muwaqqar Fm oil shales from central Jordan with abnormal enrichment of Cd, Zn, Mo, Cr, U, Cr and Se, normal V and Ni, and very low Mn and Co [3,78]. The Jordanian spurrite CM marbles that formed after the Muwaqqar oil shales inherit this enrichment and store abundant and diverse accessories (ZnO, (Mg,Zn,Ni,Cu)O, (Ca,Cd)O, Ca-U oxides, CaMoO 4 , (Zn,Cd)S, Cd(S,Se) CdS) [3,[5][6][7][8]) which are absent from CM rocks derived from the Ghareb oil shales. The latter bear only few grains of vorlanite (CaUO 4 ), vapnikite (Ca 3 UO 6 ), Cu oxides and sulfides, as well as periclase enriched in Zn and Ni.…”

A hibonite-spinel-corundum-hematite assemblage in plagioclase-clinopyroxene pyrometamorphic rocks, Hatrurim Basin, Israel: mineral chemistry, genesis and formation temperatures

“…Gross and Y. Bentor (Bentor et al , 1963; Gross, 1977 and others). In last decade more than 20 new minerals have been found within the Hatrurim Formation: barioferrite; shulamitite; murashkoite; zadovite; gurimite; vapnikite; nabimusaite; aradite; gazeevite; fluormayenite; fluorkyuygenite; negevite; halamishite; zuktamrurite; silicocarnotite; flamite; tululite and others (Murashko et al , 2011; Sharygin et al , 2013; Galuskin et al , 2014; 2015 a – c ; 2016; 2017; Galuskina et al , 2014; 2017 a , b ; Britvin et al , 2015; Sokol et al , 2015; Khoury et al , 2016). Most of these were identified in larnite and spurrite rocks and Ca-rich paralavas; and some could be used as indicator minerals to estimate the history of the rock formation.…”

Mcconnellite, CuCrO2 and ellinaite, CaCr2O4, from varicoloured spurrite marble of the Daba-Siwaqa area, Hatrurim Complex, Jordan

“…1a) collected from one of quarries (31°32′31′′N, 36°10′19′′E) in the Tulul Al Hammam area, which is in the pyrometamorphic field of the Daba-Siwaqa area, central Jordan. The varicoloured marble belongs to the upper part of the Maastrichtian–Paleogene Muwaqqar Chalk–Marl Unit (Khoury et al , 2016; Sokol et al , 2017; Khoury, 2020). This unit was transformed to varicoloured marble by pyrometamorphism, and is, therefore, included in the Hatrurim Complex (Mottled Zone of Picard, 1931).…”
