分析了IfniButtonhole和Lakhssas高原的碎屑和火山碎屑岩,以确定其出处,组成成熟度,和变更来源。地球化学,沉积物被归类为arkoses,石质砂砾,grauwackes,砂岩,石质砂砾,和富含铁的沙子,表明成分和矿物学成熟度低。高平均SiO2浓度和低Al2O3与页岩和粘土组分的低丰度一致。碎屑和火山碎屑(RDVD)岩石的地球化学特征表明,它们经历了中等至低程度的化学蚀变。一项研究还表明,花岗岩,花岗岩岩石代表来源,在风化和运输过程中,将碎屑提供给超地壳单位。主要微量元素数据表明,这些岩石主要来自长质火成岩,即花岗岩,中间来源的贡献很小。碳酸盐岩并不代表各种各样的相:白云质灰岩,钙质石灰岩,和钙盐白云石。钙质和白云质样品显示SiO2的线性增加,无论其CaO/LOI比值如何,保持相对恒定。在钙白云石石中观察到最高的SiO2含量。来自Ifni纽扣孔的RDVD的地球化学分析确定了它们的来源,成熟,和改变。主要氧化物随着二氧化硅含量的增加而减少,指示石英控制。样品,在半干旱条件下形成的,在稳定沉积下显示成熟度。他们建议使用长龙,回收源,在回收过程中具有适度的蚀变和锆石富集。在研究区,石灰岩和白云石作为适用于建筑领域的材料,适用于所有类型的混凝土。塔里韦尔组藏有下寒武纪的白云岩和石灰岩,理想的马赛克骨料。描述为颜色可变,紧凑型,同质,非常辛苦,并且抵抗改变,深蓝色的岩石形成突出的山峰。它们在花岗岩中既表现出亚碱性特征,又在白云石岩脉中表现出碱性趋势。大多数样品显示最小的改变,表明其主要元素成分用于地球化学分析的可靠性。这些花岗岩构成了用于装饰和建筑岩石目的的有价值的沉积物。
Detrital and volcanic-detrital rocks from the Ifni Buttonhole and Lakhssas Plateau were analyzed to determine their provenance, compositional maturity, and alteration source. Geochemically, the sediments were classified as arkoses, lithic arenites, grauwackes, sandstones, lithic arenites, and Fe-rich sands, indicating low compositional and mineralogical maturity. A high average SiO2 concentration and low Al2O3 were consistent with a low abundance of shale and clay components. The geochemical signatures of the detrital and volcano-detrital (RDVD) rocks indicate that they have undergone a moderate to low degree of chemical alteration. The CIA study also suggests that the granitic, granodioritic rocks represent the source provenance which, during
weathering and transport, supplied the detritus to the supra-crustal units. The major trace element data suggest that these rocks are largely derived from felsic igneous rocks, namely granitoids, with a minor contribution from intermediate sources. The carbonate rocks do not represent a wide variety of facies: dolomitic limestone, calcareous limestone, and calcaro-dolomitic chert. Calcitic and dolomitic samples show a linear increase in SiO2, regardless of their CaO/LOI ratio values, which remain relatively constant. The highest SiO2 contents are observed in the calc-dolomitic chert. Geochemical analysis of RDVD from the Ifni buttonhole determined their origin, maturity, and alteration. Major oxides decreased with higher silica content, indicating quartz control. Samples, formed under semi-arid conditions, show maturity under stable deposition. They suggest a felsic, recycled source, with moderate alteration and zircon enrichment during recycling. In the study area, limestones and dolomites serve as materials applicable in the building sector, suitable for all types of concrete. The Taliwine Formation harbors Lower Cambrian dolomites and limestones, ideal for mosaic aggregates. Described as variable in color, compact, homogeneous, very hard, and resistant to alteration, the plutonic rocks form prominent peaks. They exhibit both subalkaline characteristics in granitoids and an alkaline trend in dolerite dykes. Most samples display minimal alteration, indicating the reliability of their major element compositions for geochemical analyses. These granitoids constitute valuable deposits for ornamental and building rock purposes.
