Ranobe (fitrandrahana)
Ny toeram-pitrandrahana Ranobe dia anisan' ny fitrandrahana titanina lehibe indrindra eto Madagasikara, eo amin’ ny 40 km any avaratr’ i Toliara any atsimo-andrefan’ i Madagasikara,. Manana tahirin' akora mitentina 959 tapitrisa taonina ity toerana ity, ka ny 5,8 % amin' izany no titanina[1][2][3].
Ity tahiry ity dia ahitana ny ilmenita, izay akora ahitana titanina betsaka, izay 70 % amin' ny vokatra marihitra hovokarina. Ahitana mineraly sarobidy toy ny zirkôna sy rotila ihany koa izy io, izay, na dia 10 % amin' ny mineraly mavesatra aza, dia mandray anjara eo amin' ny 30 % amin' ny sandan' ny akora alaina[4][3].
Mikasa ny hamokatra ilmenita 600 000 taonina sy zirkôna 65 000 taonina amin' ny vokatra marihitra isan-taona mandritra ny 20 taona voalohany ny tetikasa fitrandrahana ao Ranobe . Mampiasa manodidina ny 27 % amin' ny harena an-kibon' ny tany 884 tapitrisa taonina ao Ranobe io drafitra fitrandrahana io.[4][3][5][2].
Ahafahana mampiasana fomba fitrandrahana mitafo lanitra tsotra sy mahomby ny toetran' ilay tahiry, indrindra fa ny tahan' ny tanimanga ambany (<5 %). Lalana mirefy 55 km no hitaterana ny vokatra azo mankao avaratry ny seranan-tsambon’ i Toliara, ka hanamora ny fanondranana izany any ivelany[4][6][5].
Heverina ho matanjaka ny tetikasa fitrandrahana Ranobe, hahazoana tombony ambony nefa ambany ny saran' ny famolavolana azy raha oharina amin' ny tetikasa momba ny fasika mineraly mitovy habe aminy[4][6][7].
