Ifu ya Tourmaline ni ikintu gikozwe mu ibumba rito gikomoka kuri tourmaline, amabuye y'agaciro ya borosilicate izwiho imiterere itandukanye ya shimi n'imiterere itangaje y'umubiri. Ifuru rusange ya tourmaline ni NaR3Al6 (Si6O18) (BO3)3 (OH,F)4, aho R ishobora kuba iyoni zitandukanye z'icyuma nka feri, manyeziyumu, lithiyumu, cyangwa manganese, zitanga tourmaline amabara menshi n'imiterere yayo.

Tourmaline ikorwa mu bihe byihariye bya geologi, ubusanzwe ikomoka ku miyoboro ya pegmatite n'ibidukikije bifite ubushyuhe bwinshi n'umuvuduko mwinshi. Muri pegmatites, ari amabuye akomeye ya igneous, kristu za tourmaline zikura mu bisubizo bikomoka ku bushyuhe bukungahaye kuri boron, aluminiyumu, silikoni, n'ibindi bintu by'ingenzi mu gihe cy'isesengura rya magma. Hagati aho, mu mabuye ya metamorphic, tourmaline ibaho bitewe n'imikorere ya shimi mu mabuye atandukanye y'agaciro munsi y'ubushyuhe bwinshi n'umuvuduko, nko mu gihe cyo kubaka imisozi.

Uturere twinshi dukora tourmaline ku isi yose tugira uruhare runini mu gutanga ifu ya tourmaline. Brezili igaragara nk'isoko rikomeye, ifite amateka menshi y'ubutaka bwayo yuzuyemo ibikorwa by'ubutare n'impinduka. Sri Lanka nayo igira uruhare runini, ifite imiterere yihariye y'ubutaka yorohereza ikorwa rya tourmaline. Madagasikari, izwiho ubucukuzi bwayo bwinshi, itanga tourmaline nziza cyane. Mu Bushinwa, Xinjiang na Yunnan ni isoko ry'ingenzi mu gihugu, aho imiterere y'ubutaka igoye hamwe n'ingendo za tectonic zikora bitanga imiterere myiza yo gukora amabuye y'agaciro ya tourmaline.

Nyuma yo gucukura, amabuye ya tourmaline anyura mu ntambwe nyinshi zo kuyatunganya kugira ngo abe ifu. Mbere na mbere, arasenywa mo uduce duto kugira ngo asenye imiterere y'amabuye. Nyuma yaho, binyuze mu kuyasya no kuyasya, ayo mabuye arushaho gutunganywa akavamo uduce duto. Hanyuma hakorwa gahunda zo kuyasukura kugira ngo haveho imyanda nk'indi myunyu ngugu, ibumba, n'ibintu bikomoka ku bimera, bityo hagakorwa gahunda yo kuyasukura kugira ngo haveho ifu ya tourmaline isuku n'ubwiza.

Ifu ya Tourmaline ifite akamaro kanini. Mu rwego rw'ubuzima n'imibereho myiza, ihabwa agaciro gakomeye kubera imiterere yayo yihariye y'amashanyarazi n'ubushyuhe. Iyo ihuye n'umubiri w'umuntu cyangwa ibidukikije bimwe na bimwe, ifu ya tourmaline ishobora gukora amashanyarazi make ndetse n'imirasire ya infrared. Iyi miterere yizewe ko iteza imbere gutembera kw'amaraso, yongera imikorere y'umubiri, kandi ishobora no kunoza imibereho myiza muri rusange. Mu rwego rw'ubwiza, yongerwa mu bicuruzwa byo kwita ku ruhu kubera ko ifasha mu kuruhura, kurwanya gusaza, no kuruhura uruhu. Mu rwego rw'ibidukikije, ifu ya tourmaline ishobora gukoreshwa mu gusukura amazi n'umwuka, kuko ishobora kwinjiza ibintu byangiza. Byongeye kandi, mu nganda z'ubwubatsi n'iz'ibumba, ishyirwa mu bikoresho kugira ngo inoze imiterere yayo, nko gukomera no kuramba. Muri rusange, imikorere y'ifu ya tourmaline ituma iba ingenzi mu bikorwa bitandukanye bigezweho.
