Twenty four (24) coal samples from the eight (8) working collieries of Northumberland coalfield, England, have been studied with the view to analyzing the possible location/concentration of the mineral species in coals. The results of the study showed that their clay mineral suites dominated by kaolinitic types are disseminated products at maceral boundaries, desiccation cracks and at times fissures with no established genetic evidence. The other widespread variety of mineral occurrences, notably calcite, siderite and sometime pyrite in the coal basin and traceable to precipitates in various joints, cleats, cell voids and lumens are associated/formed during epigenetic mineralization episode (post depositional phase), when the macerals have differentiated into their various entities. More importantly, these mineral concentration appears to have been partly or wholly controlled by the semifusinite/fusinite macerals (i.e. particularly those exhibiting "Bogenstruktur") as the preferred traps and/or infills for coals. With the exception of the nodular pyrite that is said to be linked to both vitrinitic and sometimes liptinitic macerals and are traceable to syngenetic mineralization episodes, the euhedral type pyrite demonstrates a complete unique behaviour by their infill of semifusinite/fusinite macerals which suggests the timing to be of post-depositional phase.

Typical Carbonaceous matter are often widespread and reveal relatively wide range of dominant organic types. The instrumental diagnosis to subject them to oxidation, combustion and/or incineration serve till date mandatory fundamental requirement in the further pursuance of their mineralogical and wet Chemical Analysis. The results of the Ash content from three (3) carbonaceous coal-and shaly coal samples from Northeastern England and Scottish fife show that the variation and/or the volatilization of the inherent sensitive elements are related to both the techniques and the sample composition. From the two techniques adopted, the high-and low-temperature methods the Ash values observed/obtained for Westfied shaly and Beaumont coal types are dependent on their derived material source-argillaceous and pure coal components. However, of the inorganic components (Ash) values that can be recovered from any carbonaceous matter, Radio-frequency method appears to suggest the accurate and reliable alternative for their subsequent geochemical appraisal. @JASEM
