Li-depositi tsa Feldspar li arotsoe haholo ka mefuta e 'meli ho latela liphatsa tsa bona tsa lefutso:
1. **Gneiss kapa Migmatitic Gneiss**: Methapo e meng e hlaha ka har'a granite kapa majoe a motheo, kapa libakeng tseo a kopanang le tsona.Ore e tsepamisitsoe haholo sebakeng sa feldspar block ea pegmatites kapa feldspar pegmatites e fapaneng.
2. **Igneous Rock Type Feldspar Deposits**: Li-deposit tsena li hlaha mafikeng a nang le asiti, a mahareng le a alkaline.Tse fumanoang mafikeng a alkaline li bohlokoa haholo, joalo ka nepheline syenite, e lateloa ke granite, albite granite, orthoclase granite, le quartz orthoclase granite deposits.
Ho ipapisitsoe le mokhoa oa ho etsa liminerale tsa feldspar, li-deposit tsa feldspar li arotsoe ka mofuta oa majoe a se nang letho, mofuta oa pegmatite, mofuta oa granite o omeletsoeng, le mofuta oa mafika a sedimentary, 'me mefuta ea majoe a pegmatite le a igneous ke eona e ka sehloohong.
