Ko te Cassiterite, e mōhiotia ana ko te konuwhā (SnO₂), te tino kōreko me te pūtake nui rawa atu o te konuwhā. Nō te rōpū kōhatu rutile, ka whakapakari i te pūnaha tetragonal, ka puta mai hei tioata poto, hei tioata rua-pīrama rānei, e mōhiotia ana mō te "tuke" takirua. Ahakoa he parauri pōuri ki te pango te nuinga o te tae nā te paru rino, ka puta hoki hei whero-parauri, kōwhai, ahakoa he kōataata kore tae i ngā tauira parakore. Ko tētahi o ōna āhuatanga tinana tino whakamārama ko tōna taumaha motuhake, mai i te 6.8 ki te 7.1, he mea whakamīharo mō te kōhatu kore-whakarewa. Nā tēnei taumaha, me te kanapa ādamanine ki te kanapa whakarewa-iti, me te pakeke Mohs 6 ki te 7, ka noho pūmau te matū me te ātete ki te hāwerewere tinana. Ko ngā momo motuhake ko te "Rākau Tīni," he momo botryoidal, he muka rānei me te whakatakotoranga porowhita e rite ana ki te rākau, me te "Tīni Awa," e tohu ana i ngā kirikiri porotaka, kua horoia e te wai i ngā putunga tuarua.
Ko te hanganga o te cassiterite e hono ana ki te whanaketanga o te magmatism granitic me ngā tukanga waiariki pāmahana tiketike. Ka whakahekea i ngā wāhanga whakamutunga o te wehewehenga magmatic, i reira ka whakakikoruatia ngā wai pūkōwhai whai tīnika ki roto i ngā pegmatites me ngā greisens. Ko ēnei wai, e whai ana i te boron, te fluorine, me te phosphorus, ka huri haere i roto i ngā whatiwhatinga o te toka kaihautū, ka whakatakoto i te cassiterite ki te taha o ngā kohuke pēnei i te quartz, te wolframite, te tourmaline, me te fluorite. I tua atu i ēnei putunga uaua tuatahi, ka puta te cassiterite ki ngā taiao whakarerekē whakapā, pēnei i ngā skarns, i reira ka pāhekoheko ngā whakaurunga magmatic ki ngā toka warowaihā. Nā tōna ātete nui ki te pirau matū me tōna kiato tiketike, ka tukua nuitia te cassiterite i tōna anga tuatahi mā te horo whenua. Kātahi ka whakahaeretia te whakakikoruatanga miihini e te mahi awaawa, moana rānei, hei hanga i ngā putunga alluvial, placer rānei e whai hua ana i te ōhanga, nā rātou i whakarato te nuinga o te whakaputanga tīnika o te ao i ngā wā o mua.
He kīanga nui te cassiterite ki te panonitanga hangarau o te ao tangata ki te Wā Parahi. Nō te 3000 BCE, i whakamahia e ngā mahi whakarewa tawhito te whakaheke i te cassiterite i roto i ngā ahi waro hei whakaputa i te tine, kātahi ka whakaranua ki te parahi hei hanga i te parahi—he rawa kaha ake, he māmā ake hoki te whakarewa i te parahi mā. Nā tēnei mahi hou i huri te hanga o ngā taputapu, ngā patu, me ngā taonga whakanui. Ko te hiranga rautaki o te tine i whakatū i ngā ara hokohoko tawhito whānui, me ngā iwi whakatere waka pērā i ngā Phoenicians e haere ana ki ngā “Cassiterides” (e hono ana ki Cornwall me ngā Moutere Scilly) ki te whai rawa. I te Wā Hurihanga Ahumahi, i piki te hiahia mō te cassiterite, e akiaki ana i ngā whanaketanga o te keri hōhonu me te hangarau papu mamaoa. I roto i te horopaki hou, ahakoa kei te noho tonu tana tūnga hītori i roto i te mahi whakarewa, he mea nui te cassiterite mō te ahumahi hiko o te ao, hei rawa mata mō ngā whakarewa kore-arahi e hiahiatia ana i roto i te hanga pūngao ā-ira me te papa taiawhio.
Te Hanganga Karaihe me ngā Āhuatanga Ahumoana-Ahupūngao o te Cassiterite
Ko te Cassiterite e whakatotoka ana i roto i te pūnaha tioata tetragonal, inarā i roto i te rōpū mokowā P4₂/mnm, he hanganga e whai tahi ana me ētahi atu mema o te rōpū rutile. Ko te whakaritenga ngota e mau ana i ngā kātioka konutai (Sn) e ruruku ana ki ngā anioni hāora (O) e ono i roto i te āhuahanga octahedral, ā, e karapotia ana ia ngota hāora e ngā ngota konutai e toru i roto i te whirihoranga tapatoru papatahi. Nā tēnei whakatakotoranga kikī e whai wāhi ana ki te kiato whakamīharo me te taupū whakaata teitei o te kōhuke. I runga i te āhua, ka tipu te Cassiterite hei tioata porotītaha poto, mārō, hei tioata dipyramidal rānei. Ko tētahi tohu o tōna āhua tioata ko te puta pinepine o te māhanga whakapā, te māhanga urunga rānei, inarā te māhanga "tuke", e hanga ana i te koki 112° motuhake. Ka whakaatahia tēnei pakari hanganga i roto i tōna mauroa tinana, e kitea ana i te pakeke o Mohs 6 ki te 7 me te kore o te wehenga mārama, e puta ana i te whati whati ā-papa-kōpura ki te kōpīpī.
I roto i te matū, ko te cassiterite te nuinga o te hāora konuheka (SnO₂), ahakoa he uaua te kitea o ngā tauira māori i te āhua parakore. He maha ngā wā ka uru mai te rino, te niobium, te tantalum, te konupora, me te tungsten ki roto i te whakatakotoranga tioata mā te whakakapinga katote. Ko ēnei huānga tohu te take o te whānuitanga o ngā tae o te kohuke, nā te mea he kore tae, he mā rānei te SnO₂ parakore; ko te poke rino, inā koa, e whakaputa ana i te tae hāura hohonu ki te pango. Ko tētahi o ngā āhuatanga matū tino nui o te cassiterite ko tōna āhua tino pakeke me te kore e whakarewa ki ngā waikawa, e taea ai e ia te noho tonu i te taiao i muri i te horo o tōna toka kaihautū. I tua atu, ko tōna taumaha motuhake teitei o 6.8 ki te 7.1 he āhuatanga whakatau tino nui, e wehewehe ana i a ia mai i ngā kohuke rite te āhua engari māmā ake pērā i te tourmaline, te sphalerite rānei. Nā tēnei huinga o te pūmautanga hanganga me te pūmautanga matū e noho tonu ai te cassiterite hei puna tino pono me te kukū o te konuheka mō te tangohanga ahumahi.
