The potential for lithium in the UK
www2.bgs.ac.ukfound in pegmatite deposits. However, hectorite (Na 0.3(Mg,Li) 3Si 4O 10(OH) 2), a lithium-rich smectite clay mineral, and jadarite (LiNaSiB 3O 7(OH)), a lithium-bearing borosilicate mineral, may be important sources of lithium in the future. Lithium extraction from brines is chiefly from continental brine deposits, such as the salt lakes and salt

Typically, they crop out near evolved, peraluminous granites and leucogran-ites from which they are inferred to be derived by fractional crystallization.
