X-Ray diffraction results for the study mine are mainly represented by two phases (phosphatic and non-phosphatic). First phase is represented by apatite (fluorapatite) which is the dominant. The second phase includes carbonate minerals; calcite, dolomite, evaporated mineral (gypsum), sulphide mineral (pyrite), in addition to quartz as a silicate mineral. These results are confirmed by the petrographic study. The detailed microscopic examinations indicate that the phosphorites at the study mine is essentially composed of phosphatic lithoclasts (mainly collophane), phosphatic bioclasts (bone fragments, spines and teeth of vertebrates such as shark fish as well as coprolites), opaques, and quartz embedded in a microcrystalline phosphatic matrix (contains some of dahllite) associated with a microcrystalline quartz according to their decreasing order of abundance. The paragenetic sequence of the studied phosphorites is as follows: fluorapatite, collophane then followed by dahllite. The redox-sensitive trace elements, its ratios, authigenic uranium as well as Fe/Ti can be signifying the redox conditions. Also, they revealed that the study rocks are deposited under the oxic to anoxic environment coupled with hydrothermal solution. The trace and rare earth elements are generally associated with phosphatic rocks. Thus, the phosphatic rocks of Um El-Huwtat mine, Quseir can be considered as sources of trace and rare earth elements. Also, pyrite can be considered as another possible source for REEs. The studied phosphatic rocks characterized by light REE (LREE = 69 ppm) enrichment than heavy REE (HREE = 25 ppm). All the recoded values of the heavy metals for the study mine are higher than those in Tunisia (400.3 ppm), Morocco (571.75 ppm) and Jordan (187 ppm). The post-depositional conditions are responsible for the enrichment of U and Th and/or intensive chemical weathering in Quseir area. Enrichment Factor (EF) indicated that the enrichment or deletion of the elements may be a function of that association and the origins of the various phosphate fractions. The studied phosphatic rocks are suitable for industrialized fertilizers according to the world guides.

研究矿山的 X 射线衍射结果主要由两相（磷酸盐和非磷酸盐）表示。第一相由占主导地位的磷灰石（氟磷灰石）代表。第二阶段包括碳酸盐矿物；方解石、白云石、蒸发矿物（石膏）、硫化物矿物（黄铁矿），此外还有石英作为硅酸盐矿物。岩相学研究证实了这些结果。详细的显微镜检查表明，研究矿中的磷矿石主要由含磷碎石（主要是胶纸）、含磷生物碎屑（鲨鱼鱼等脊椎动物的骨头碎片、刺和牙齿以及粪石）、不透明、和嵌入在微晶磷酸盐基质中的石英（包含一些粗线石），根据它们的丰度递减顺序与微晶石英相关联。所研究的磷灰石的共生序列如下：氟磷灰石、树脂石、然后是粗壮线石。对氧化还原敏感的微量元素、其比例、自生铀以及 Fe/Ti 可以表示氧化还原条件。此外，他们还透露，研究岩石是在有氧到缺氧的环境以及热液溶液下沉积的。微量元素和稀土元素一般与磷质岩伴生。因此，Quseir 的 Um El-Huwtat 矿的磷质岩可以被认为是微量元素和稀土元素的来源。此外，黄铁矿可被视为另一种可能的 REE 来源。所研究的磷质岩特征是轻稀土（LREE = 69 ppm）比重稀土（HREE = 25 ppm）富集。研究矿山的所有重金属重新编码值均高于突尼斯（400.3 ppm）、摩洛哥（571.75 ppm）和约旦（187 ppm）。沉积后条件是造成库塞尔地区 U 和 Th 富集和/或强烈化学风化的原因。富集因子 (EF) 表明元素的富集或缺失可能是该关联和各种磷酸盐部分的来源的函数。根据世界指南，所研究的磷质岩适用于工业化肥料。摩洛哥（571.75 ppm）和约旦（187 ppm）。沉积后条件是造成库塞尔地区 U 和 Th 富集和/或强烈化学风化的原因。富集因子 (EF) 表明元素的富集或缺失可能是该关联和各种磷酸盐部分的来源的函数。根据世界指南，所研究的磷质岩适用于工业化肥料。摩洛哥（571.75 ppm）和约旦（187 ppm）。沉积后条件是造成库塞尔地区 U 和 Th 富集和/或强烈化学风化的原因。富集因子 (EF) 表明元素的富集或缺失可能是该关联和各种磷酸盐部分的来源的函数。根据世界指南，所研究的磷质岩适用于工业化肥料。
