An innovative chemical quantitative mineral analysis (CQMA) was successfully tested on a cordierite-based clay ceramic sample to quantify crystalline and amorphous components. The accuracy of this method was demonstrated on an added module to the CQMA program that used oxide formulas of amorphous phases obtained by energy dispersive X-ray spectroscopy (EDS) microprobe chemical analysis. This CQMA method was tested for three variants calculated using chemical analysis, i.e., X-ray diffraction (XRD) identification of crystalline (cordierite and enstatite) and amorphous phases by scanning electron microscopy (SEM)/EDS texture and microanalyses. The test results from CQMA suggest their application possibilities as well as the limits of their utilization.

A total of 77 pottery shards originating from the Middle Jomon period (2500–1500 BC) were excavated from the Hinoki site in Tochigi, Japan. Fifty-five of those were Atamadai type pottery, which might contain some temper fragments from the manufacturing process. The pottery shards were analyzed by X-ray diffractometry (XRD). The mineral analyses were compared with the river sands around Mt. Tsukuba to demonstrate the temper's origin of the Atamadai type pottery. Their XRD profiles revealed the following solid solutions which could be fingerprint minerals: biotite for the temper and plagioclase, and hornblende for the clay and temper. These minerals might indicate the origin of each sample because their d-spacings depended on the solid solution composition reflecting their geological characteristics.

Rock examinations for mining and commercial use are a vital process to save money and time. A variety of methods and approaches have been used to analyze rocks and among them, X-ray fluorescence (XRF), and X-ray diffraction (XRD) techniques proved to be an accurate method. This research was conducted to evaluate the utility and reliability of XRF and XRD to analyze the major and trace elements of rocks as well as their crystalline structures. Results showed that XRF and XRD techniques are fast and reliable, nondestructive and non-invasive analytical tools for mineral analysis, particularly for rocks. For this purpose, the analysis of 28 samples of rocks, which collected from three different places of Kurdistan region-Iraq, is reported. These places are Haybat Sultan (HS) region in Koya city as well as TaqTaq (TA) and Garmuk (GT) district nearby Koya city. Throughout this analysis, 34 major and trace elements were detected in the rocks collected from HS region, whereas forty major and trace elements were detected in the rocks collected from TA district and GT district. In addition, it was found that the structures of these rocks were crystalline in nature. This was proved through the value of diffracted angle and it was found that the majority of these rocks are oxides. The external view (the appearance) of all collected rocks was also discussed and it was found that each rock consists of a variety of minerals which will be the reason that each rock has a specific color.

Common buckwheat (Fagopyrum esculentum Moench) and tartary buckwheat (Fagopyrum tataricum Gaerth.) are underutilized pseudo-cereals and both considered nutritional food. Eight common and eleven tartary buckwheat accessions acquired from Slovenian plant gene bank were grown at the experimental fields of the Agricultural Institute of Slovenia in 2014. Dried grains were homogenised and analysed for several nutrient parameters: moisture content (11–14% dry weight, DW), total proteins (11–16 % DW), dietary fibre (15–19 % DW), ash (2–6 % DW) and total fats (1.8–2.6 % DW). The fatty acids (C14:0, C16:0, C18:0, C18:1n9, C18:2n6, C18:3n3, C20:0) were determined using gas chromatography, free amino acids (Gly, Glu, Arg, Lys, Asp, Ser, Phe, Ala, Val, Thr, Pro, Ile, Met, His, Cys, Leu, Tyr) by the high-performance liquid chromatography and multi-mineral analysis (K, P, Si, S, Ca, Fe, Cl, Ti, Zn) using X-ray fluorescence spectroscopy. The results show significant differences between two buckwheat species, and their gene bank accessions for investigated nutritional parameters.
