Minerals of the Zn-Cd-S-Se system that formed by moderately reduced ~800–850 °C combustion metamorphic (CM) alteration of marly sediments were found in marbles from central Jordan. Their precursor sediments contain Se- and Ni-enriched authigenic pyrite and ZnS modifications with high Cd enrichment (up to ~10 wt%) and elevated concentrations of Cu, Sb, Ag, Mo, and Pb. The marbles are composed of calcite, carbonate-fluorapatite, spurrite, and brownmillerite and characterized by high P, Zn, Cd, U, and elevated Se, Ni, V, and Mo contents. Main accessories are either Zn-bearing oxides or sphalerite, greenockite, and Ca-Fe-Ni-Cu-O-S-Se oxychalcogenides. CM alteration lead to compositional homogenization of metamorphic sphalerite, for which trace-element suites become less diverse than in the authigenic ZnS. The CM sphalerites contain up to ~14 wt% Cd and ~6.7 wt% Se but are poor in Fe (means 1.4–2.2 wt%), and bear 100–250 ppm Co, Ni, and Hg. Sphalerite (Zn,Cd,Fe)(S,O,Se)_cub is a homogeneous solid solution with a unit cell smaller than in ZnS_cub as a result of S²⁻ → O²⁻ substitution (a = 5.40852(12) Å, V = 158.211(6) ų). The amount of lattice-bound oxygen in the CM sphalerite is within the range for synthetic ZnS_1−xO_x crystals (0 < x ≤ 0.05) growing at 900 °C.

Zn-Cd-Se-富集燃烧变质大理石的超高温闪锌矿，Daba配合物，约旦中部：共生，化学和结构

在约旦中部的大理石中发现了由锌沉积物形成的锌-镉-硒-硒系统矿物，该矿物通过适当降低约800-850°C的马氏沉积物的燃烧变质（CM）改变而形成。它们的前体沉积物含有富硒和富镍的自生黄铁矿和ZnS变质，具有高Cd富集度（约10 wt％）和较高浓度的Cu，Sb，Ag，Mo和Pb。大理石由方解石，碳酸盐-氟磷灰石，亚铁酸盐和褐煤组成，其特征在于高P，Zn，Cd，U和高Se，Ni，V和Mo含量。主要附件是含锌氧化物或闪锌矿，绿辉石和Ca-Fe-Ni-Cu-OS-Se氧化硫属元素化物。CM的变化导致变质闪锌矿的成分均质化，为此，微量元素组的多样性要小于自生ZnS。CM闪锌矿含有高达〜14 wt％的Cd和〜6.7 wt％的Se，但贫铁（含量为1.4–2.2 wt％），并且含有100–250 ppm的Co，Ni和Hg。闪锌矿（Zn，Cd，Fe）（S，O，Se）_幼兽是具有单元电池比的ZnS小的均质固溶_CUB作为一个结果S ^2- →O; ^2-取代（一= 5.40852（12）A，V = 158.211（6）³）。晶格结合的氧在CM闪锌矿的量在该范围内，用于合成的ZnS _1-x Ö _X晶体（0 < X ≤0.05）在900℃下生长。
