The mineralogical compositions of the Gerinya claystone, Patti Formation, Southern Bida Basin, Nigeria, were investigated to infer their sedimentological process and industrial application. Mineralogical analysis of the claystone was carried out using the X-ray diffraction (XRD) method. The diffractogram peaks aided the identification of the clay and non-clay minerals in the study area. The XRD showed kaolinite as the major clay mineral with compositions ranging from 10.8 - 67.6 wt%. The non-clay minerals were quartz, anatase, diopside, goethite, hematite, rutile, muscovite and microcline. Among the non-clay minerals, quartz had the highest percentage mineralogical composition of 21.2 to 83.4 wt%. The mineral assemblage is typical of a hot and humid climate where chemical alteration and hydrolysis of silicate minerals are severe. The sediments are of mafic and felsic crystalline rocks origin. The sediments are of low energy floodplain/interchannel depositional environment. The Gerinya claystone vary from low to high porosity and very low to low permeability. The claystone can be used as clay liners and as raw material for ceramic production. The application of the claystones in fertiliser production will require some processing. The claystone can be used for haemorrhage control in the pharmacological/medical sector. Although, the ingestion of the claystones could lead to dental damage and possible perforation of the sigmoid colon in the gastrointestinal tract.

It was analyzed the influence of factors on the structural strength and durability of adhesive compounds in the roots of the book blocks. On the basis of differential-thermal, X-ray structural and microscopic analysis of hot-melt adhesives and paper, from which book blocks are made, it was investigated their structural build and physical-chemical interaction at the macro and micro levels, the features of the formation of adhesive compounds were revealed.

Przeanalizowano wpływ czynników na wytrzymałość strukturalną i trwałość związków adhezyjnych w grzbietach wkładów książek. Na podstawie analizy różnicowo-termicznej, rentgenowskiej i mikroskopowej klejów termotopliwych i papieru, z którego wykonano wkłady książkowe, zbadano ich strukturalną budowę oraz współdziałanie fizykochemiczne na poziomach makro- i mikropodstawowych, zmodelowano osobliwości tworzenia połączeń klejowych.
