Dear Reza,
I hope you are doing well. Recently we published a review paper on magmatic uranium deposits which may be useful.

Petrologic exploration criteria for magmatism-related uranium deposits: a review
Internationsl Geology Review
According to several sources, uranium deposits are often associated with granitic rocks. For instance, the mid-European Variscan uranium province, extending over 2,000 km from Spain to the Bohemian Massif, is known for uranium deposits related to late Carboniferous peraluminous leucogranites. In addition, the Longhuashan, Youdong, and Changjiang granites have been identified as favorable uranium sources for forming uranium deposits in their respective areas.
As for the properties of alkali granites, they are a type of granite rich in the mineral potassium feldspar (K-spar), which gives the rock a predominant pink to reddish hue. Alkali granites are dense rocks with a phaneritic texture, meaning the mineral grains are large enough to be identified with the naked eye. The sodic-amphiboles and pyroxenes (riebeckite, arfvedsonite, aegirine) are characteristic of the alkali granites. If neither feldspar is in great excess, neither amphibole nor pyroxene is likely to be an essential constituent; the other minerals will ordinarily be biotite, muscovite, or both.
Please note that the relationship between uranium deposits and alkali granites can be complex and depends on various geological factors.
