“…Correspondingly, the rocks are rich in sulfide sulfur (and/or products of its oxidation): 3.77 wt % SO3 on average ( Table 4). The S 2− -TOC correlation is especially evident in fresh (non-oxidized) oil shales sampled from boreholes [78] and is as high as R 2 = 0.92 (N = 9) in those from Rotem borehole.…”

“…The Hatrurim Fm CM rocks formed by isochemical metamorphism of bitumen-rich chalky sediments ('oil shales') of the Maastrichtian Ghareb Fm or, less often, Paleocene marls of the Taqiye Fm [62]. Their stratigraphic equivalents in Jordan appear as bioproductive chalky-marly sediments of the Muwaqqar Fm, which are sedimentary precursors of CM spurrite marbles [3,6,77,78]. The Ghareb Fm bituminous chalks (oil shales) are hypersaline shallow marine sediments mainly consisting of biogenic calcite with minor contributions of detrital quartz, clay minerals, apatite or phosphorite matter, and pyrite ( Figure 4 The Maastrichtian bioproductive chalks and marls contain 8.52 wt % of total organic carbon (TOC) on average, with S-rich (up to 12 wt %) type II kerogen organic matter consisting of degraded marine algae and phytoplankton [3,69,73,78,79].…”

“…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 contents of As, Cd, Co, Mn, Mo, and U can vary broadly depending on the environment in which the oil shales were deposited. 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.…”

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

This is the first attempt to provide a general mineralogical and geochemical survey of natural Ca 2 SiO 4 -bearing combustion metamorphic (CM) rocks produced by annealing and decarbonation of bioproductive Maastrichtian oil shales in the Hatrurim Basin (Negev Desert, Israel). We present a synthesis of data collected for fifteen years on thirty nine minerals existing as fairly large grains suitable for analytical examination. The Hatrurim Ca 2 SiO 4 -bearing CM rocks, which are natural analogs of industrial cement clinker, have been studied comprehensively, with a focus on several key issues: major-and trace-element compositions of the rocks and their sedimentary precursors; mineral chemistry of rock-forming phases; accessory mineralogy; incorporation of heavy metals and other trace elements into different phases of clinker-like natural assemblages; role of trace elements in stabilization/destabilization of Ca 2 SiO 4 polymorphic modifications; mineralogical diversity of Ca 2 SiO 4 -bearing CM rocks and trace element partitioning during high-temperature-low-pressure anhydrous sintering. The reported results have implications for mineral formation and element partitioning during high-temperature-low-pressure combustion metamorphism of trace element-loaded bituminous marine chalky sediments ("oil shales") as well as for the joint effect of multiple elements on the properties and hydration behavior of crystalline phases in industrial cement clinkers.

Geochemistry and stable isotopes of the upper Campanian–lower Maastrichtian phosphorite‐bearing sequence, Central Jordan: Implications for their age, origin, and diagenesis

View full text Add to dashboard Cite

Three major lithofacies have been described in Lajjun area, central Jordan, including the phosphorite and intercalated limestone of the Al-Hisa Phosphorite Formation, as well as the Muwaqqar Chalk Marl Formation. 87 Sr/ 86 Sr isotopic data indicate a late Campanian age for the Al-Hisa Phosphorite Formation, whereas the overlying chalk of the Muwaqqar Formation contains the lowest Maastrichtian planktic foraminiferal zone of Rugoglobigerina hexacamerata (CF8b). The phosphorites are of reworked origin as inferred from the homogeneous texture with lack of any concentric structure in the phosphatic pellets and the presence of bone fragments inside the phosphatic pellets, which are filled with phosphatic mud similar to the matrix of phosphatic pellet. They still reflect the original seawater rare-earth pattern, as indicated from the similarity in their rare-earth element (REE) concentration and patterns with seawater. Positive correlations between P 2 O 5 and Fe 2 O 3 , TiO 2 and K 2 O, relatively high rare-earth contents, and similarity in (Nd/Yb) SN ratio to the modern shallow seawater suggest a continental marginal depositional environment for the limestone and chalk facies. δ 13 C values are lower and more variable compared with the estimated global range of upper Campanian-lowerMaastrichtian δ 13 C values in shelf and oceanic basins. This indicates a diagenetic effect on the δ 13 C isotopes and suggests that a significant proportion of carbonate ions could have been resulted from the organic carbon oxidation. Three third-order depositional sequences matching with the global and regional sea-level patterns are identified in the studied section based on vertical facies changes. The basal transgressive surface of each sequence is constantly characterized by a phosphatic horizon.
