The Parauapebas meteorite, an ordinary chondrite, was investigated through a systematic classification method, applying non-destructive analytical techniques: Electron Microprobe Micro-Analyzer (EPMA), X-Ray Fluorescence (XRF), Proton-Induced X-Ray Emission (PIXE), Cathodoluminescence (CL), and Optical Microscopy (OM). The goal was to achieve a complete and detailed chemical and petrological description of the official Parauapebas meteorite (MB 107). Additionally an inter-technique comparison was included for the bulk chemical composition obtained by means of the X-ray fluorescence PIXE and XRF techniques. The measured elemental compositions were compared to XRF and INAA average values reported in previous works on chondrites. The physical properties, such as density and magnetic susceptibility, of Parauapebas meteorite were also included as a tool for the chemical group classification. The meteorite is rich in iron metal, except into the silicates, thus Parauapebas is an H chemical group chondrite. Nevertheless some elemental compositions were found within the range of L chemical group chondrites. It presents two different lithologies with homogeneous chemistry observed in the analyzed thin sections, which point the meteorite as a genomict breccia (indicated by shock melt veins) formed by petrologic type 4 and 5. A shock stage S3/S4 is indicated by the olivine crystals with undulatory extinction, irregular and some planar fractures and a weak mosaicism, Neumann lines in iron-nickel, in addition to the presence of shock melt veins and pockets. The weathering degree is the lowest (W0), since the fragment was recovered soon after the fall.

Parauapebas 陨石是一种普通球粒陨石，通过系统分类方法进行了研究，应用无损分析技术：电子微探针微分析仪 (EPMA)、X 射线荧光 (XRF)、质子诱导 X 射线发射 (PIXE) 、阴极发光 (CL) 和光学显微镜 (OM)。目标是对官方的 Parauapebas 陨石 (MB 107) 进行完整和详细的化学和岩石学描述。另外，还包括通过X射线荧光PIXE和XRF技术获得的大分子化学成分的技术间比较。将测量的元素组成与先前关于球粒陨石的工作中报告的 XRF 和 INAA 平均值进行比较。物理特性，如密度和磁化率，Parauapebas 陨石也被包括作为化学组分类的工具。陨石富含铁金属，除了硅酸盐，因此帕劳阿佩巴斯是一种 H 化学组球粒陨石。尽管如此，在 L 化学组球粒陨石的范围内发现了一些元素组成。它呈现了两种不同的岩性，在分析的薄片中观察到的均质化学，这表明陨石是由 4 型和 5 型岩石学形成的基因组角砾岩（由冲击熔脉表示）。橄榄石晶体表示冲击阶段 S3/S4波状消光、不规则和一些平面断裂和弱镶嵌，铁镍中的诺依曼线，以及冲击熔体脉和口袋的存在。耐候度最低（W0），因为碎片在坠落后不久就被回收了。
