Upfu hweTourmaline chinhu chakakuyiwa zvakanaka chinobva kuTourmaline, chicherwa chakaoma cheborosilicate chinozivikanwa nekuumbwa kwaro kwakasiyana-siyana kwemakemikoro uye hunhu hwayo hunoshamisa. Fomura yemakemikari yeTourmaline ndeyeNaR3​Al6​(Si6​O18​)(BO3​)3​(OH,F)4​, uko R inogona kuva maion akasiyana-siyana esimbi akadai sesimbi, magnesium, lithium, kana manganese, ayo anopa tourmaline mavara akasiyana-siyana uye hunhu hwakasiyana-siyana.

Yakaumbwa pasi pemamiriro chaiwo e geological, tourmaline inowanzo bva kuma pegmatite dikes uye munzvimbo dzine tembiricha yakakwira, ine kumanikidzwa kwakakwira. Mu pegmatites, idzo dziri matombo akaomarara, makristaro etourmaline anokura kubva mu hydrothermal solutions akapfuma mu boron, aluminium, silicon, nezvimwe zvinhu zvakakosha panguva yekupedzisira kwe crystallization ye magma. Panguva imwecheteyo, mumatombo akachinja, tourmaline inoumbwa nekuda kwekuita kwemakemikari pakati pezvicherwa zvakasiyana pasi pekupisa kwakanyanya uye kumanikidzwa, senge panguva yekuvaka makomo.

Nzvimbo huru dzinogadzira tourmaline pasi rese dzinobatsira zvikuru mukuwanikwa kweupfu hwetourmaline. Brazil inoonekwa senzvimbo inotungamira, ichiva nenzvimbo yakakura nekuda kwenhoroondo yayo yakakura ye geology yakazadzwa nemabasa eigneous uye metamorphic. Sri Lanka inoitawo basa rakakosha, ine chimiro chayo che geology chakasiyana chinobatsira kuumbwa kwetourmaline. Madagascar, inozivikanwa nekusiyana kwayo kwezvicherwa, inopa huwandu hwakawanda hwe tourmaline yemhando yepamusoro. MuChina, Xinjiang neYunnan inzvimbo dzakakosha dzemuno, uko nzvimbo dzakaoma dze geology uye kufamba kwe tectonic kunogadzira mamiriro akanaka ekuumbwa kwe tourmaline ore.

Mushure mekuchera, dombo reTourmaline rinoitwa matanho akawanda ekugadzirisa kuti rive upfu. Pakutanga, rinopwanywa kuita zvidimbu zvidiki kuti riparadze chimiro chedombo. Zvadaro, kuburikidza nekukuya nekukuya, dombo racho rinonatswazve kuita zvidimbu zvidiki. Maitiro ekuchenesa anozoitwa kubvisa tsvina senge zvimwe zvicherwa, ivhu, nezvinhu zvakasikwa, zvichiita kuti hupfu hweTourmaline huve hwakachena uye hwakanaka.

Upfu hweTourmaline hune mashandisirwo akasiyana-siyana. Muindasitiri yehutano, hunokosheswa zvikuru nekuda kwehunhu hwahwo hwakasiyana hwemagetsi nekupisa. Kana hukasangana nemuviri wemunhu kana munzvimbo dzakati, upfu hweTourmaline hunogona kugadzira magetsi asina simba uye mwaranzi ye infrared. Hunhu uhwu hunotendwa kuti hunokurudzira kutenderera kweropa, hunosimudzira metabolism, uye hunogona kuvandudza hutano hwese. Mundima yezvizoro, hunowedzerwa kuzvigadzirwa zvekuchengetedza ganda nekuda kwehunyoro hwayo, hunodzivirira kukwegura, uye hunyorovesa ganda. Muchikamu chezvakatipoteredza, upfu hweTourmaline hunogona kushandiswa kuchenesa mvura nemhepo, sezvo huchigona kunyudza zvinhu zvinokuvadza. Pamusoro pezvo, mumaindasitiri ekuvaka neceramics, hunosanganiswa nezvinhu zvekuvandudza hunhu hwahwo hwepanyama, senge simba nekugara kwenguva refu. Kazhinji, kushanduka-shanduka kweupfu hweTourmaline kunoita kuti ive chinhu chakakosha mumashandisirwo akasiyana-siyana emazuva ano.
