The late Neoproterozoic Hazara Formation along the Lora Maqsood Road near Haripur, Lesser Himalayas, North Pakistan, is studied for sedimentology, petrography, and major and trace element analysis to determine the paleoenvironment, provenance, paleoweathring intensity, and tectonic settings. The Hazara Formation is characterized by greywacke sandstone, siltstone, shale, argillite, claystone, limestone, and coarsening and finning upward turbidite lithofacies. Based on bedding style, grain size, and sedimentary structures, 11 types of lithofacies were identified within the sequence. The macroscopic studies indicate that the sequence has undergone through slight metamorphism although the texture is altered sedimentary features and bed geometries are well preserved. Compaction seems to affect the part of argillaceous sediments of an enormous thickness of the Hazara Formation to make slate-like appearance which may preferably be called argillites. The same effect is seen on sandstone to make it so hard to name it orthoquartzite. Petrographic analysis of limestone reveals that the limestone is micritic in nature; stylolites and pressure solution structures are also present in the limestone. The petrographic analysis of sandstone categorized it as feldspathic greywacke in the QFR diagram. The quartz content is higher in sandstone and may reach to 70% which indicates a weathered felsic source. The petrographic analysis suggests a continental block provenance with stable craton and an uplifted basement source. The Chemical Index of Alteration and the Chemical Index of Weathering values indicate moderate to high weathering conditions with a warm and moist climate in the source region. A sedimentary-tectonic model based on the geochemical data of sandstone indicates deposition along with active continental margin tectonic settings. The paleocurrent flow analysis indicates that the dominant source region of the sediments of the Hazara Formation was situated south to southeast, which may probably be the central Indian craton, Aravali orogeny, and Bundelkhand craton of southern India.

沿巴基斯坦北部小喜马拉雅山哈里普尔附近Lora Maqsood路的新元古代晚期哈扎拉岩层进行了沉积学，岩相学以及主要和微量元素分析研究，以确定古环境，物源，古动物强度和构造背景。哈扎拉地层的特征是格雷瓦克砂岩，粉砂岩，页岩，泥锌矿，粘土岩，石灰岩，并向上浊化和浊化浊质岩相。根据层理样式，粒度和沉积结构，在该序列中识别出11种岩相类型。宏观研究表明，尽管质地改变了沉积特征，并且床的几何形状得到了很好的保留，但该序列经历了轻微的变质作用。压实似乎影响了哈扎拉地层厚度很大的泥质沉积物的部分，使其呈板岩状外观，因此最好称其为泥质。在砂岩上看到了相同的效果，因此很难将其命名为正石英岩。石灰石的岩石学分析表明，该石灰石是微晶的。石灰石中还存在铁笔石和压力溶液结构。砂岩的岩石学分析在QFR图中将其归类为长石质greywacke。砂岩中的石英含量较高，可能达到70％，表明风化的长英质来源。岩石学分析表明，大陆块源具有稳定的克拉通和隆起的基底源。化学变化指数和耐候性的化学指数值表明中度至高度的耐候性条件，源区气候温暖湿润。基于砂岩地球化学数据的沉积构造模型表明沉积以及活跃的大陆边缘构造环境。古流分析表明，哈扎拉组沉积物的主要来源区位于南部至东南部，可能是印度中部克拉通，阿拉瓦利造山带和印度南部的邦德尔坎德克拉通。
