It is found in Canada, India, Norway and USSR. The most notable difference is the absence or very low quantity of quartz while it is an essential component of granite. Syenitic rock that contains quartz can not contain feldspathoids and vice versa — foid-bearing and foid syenites contain no quartz. Synonyms. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Foid syenites contain significant amount of relatively rare silicate minerals known as feldspathoids (F) which are called foids for simplicity. The clay clasts or particles in shale are less than 0.004 millimeters in diameter, so the structure of the rock only becomes visible under magnification. In the Kola Peninsula of Russia two giant nepheline syenite Although feldspar-like in its chemistry, mineralogically it is an igneous rock combination of nepheline, microcline, albite and minor minerals like mica, hornblende and magnetite. The dominant lithology is nepheline syenite, but alkali syenite and granite occur at Mphompha and pyroxenites outcrop adjacent to, and within, the Ilomba intrusion.
