Tikanga Ine Pūoro Tensor Katoa i roto i te Ahupūngao Matawhenua
Pendahuluan
He tikanga hou te Full Tensor Gradiometry (FTG) i roto i te ao matawhenua. E whakamahia ana tēnei tikanga hei ine i te pikinga o te papa tōpana, e taea ai te whakarato i ngā mōhiohio taipitopito mō te hanganga o raro i te whenua. Kua whakamahia tēnei tikanga i roto i ngā momo tono, tae atu ki te tūhuratanga o ngā rauemi taiao pērā i te hinu me te hau, tae atu ki ngā rangahau matawhenua me te whaipara tangata.
Ngā Mātāpono Taketake o te Gradiometry Tensor Katoa
Ka whakamahia e te Full Tensor Gradiometry te mātāpono o te kaha ā-papatipu, arā, te kaha kukume i waenga i ngā papatipu e rua. Ka rerekē te papa ā-papatipu o te Ao puta noa i ngā wāhi nā te rerekētanga o te mātotoru o te toka o raro i te mata. I roto i te FTG, ka ine te taputapu ine i te papa ā-papatipu ehara i te mea ko te papa ā-papatipu anake engari ko tōna pikinga (huringa) hoki i roto i ngā āhuatanga e toru.
Ko te tensor gradient scale he matihiko 3×3 e tohu ana i ngā wāhanga e iwa o te gradient scale o te mara scale. Ko te tikanga ka taea e te FTG te whakarato i ngā mōhiohio taipitopito atu i ngā tikanga tuku iho e ine ana i te wāhanga poutū o te scale scale anake. Ko ngā wāhanga o tēnei tensor ko:
– Gxx, Gxy, Gxz
– Kiki, Kiki, Kiki
– Gzx, Gzy, Gzz
Ko ia wāhanga e tohu ana i te huringa o te papa tōpana i tētahi ahunga motuhake. Hei tauira, ko Gxx te huringa o te papa tōpana i te tuaka-x e pā ana ki tōna tūranga i te tuaka-x. Mā te ine i ngā wāhanga e iwa katoa ka homai he mōhiohio whai kiko mō te tohatoha o te papatipu i raro i te mata o te Ao.
Ngā Utauta me ngā Hangarau
Ko ngā inenga FTG me whakamahi i ngā taputapu tino tairongo, tino tika hoki. Ko ngā inenga taumaha ngā taputapu matua e whakamahia ana i tēnei tikanga. He maha ngā wā ka whakanohoia ēnei taputapu ki runga i ngā waka rererangi, ki ngā hērakapeta rānei mō ngā rangahau ā-rangi, ahakoa ka taea hoki te whakamahi i runga whenua.
Ko tētahi momo ine tere e whakamahia whānuitia ana ko te Pūrere Whakararu Kuantum Nui (SQUID), e mōhiotia ana mō tōna tairongo teitei mō te ine i ngā papa aukume me ngā papa tōpana. I roto i ngā rangahau rangi, ka honoa tēnei taputapu ki ngā pūnaha whakatere me te GPS hei whakarite kia tika te tūnga o ngā raraunga kua kohia.
Ngā tono i roto i te tūhuratanga rauemi
Te Tūhuratanga Hinu me te Hau
Kua waiho te FTG hei taputapu tino nui mō te tūhuratanga hinu me te hau. Mā te kaha ki te kite i ngā rerekētanga iti o te mātotoru o te toka, ka taea e te FTG te āwhina ki te tautuhi i ngā hanganga whenua kei roto pea te hinu, te hau rānei. Hei tauira, he maha ngā wā ka kitea ngā mahanga hauwaiwai i roto i ngā anticlines, i ngā domes tote, i ngā mahanga stratigraphic rānei. Mā te tautuhi i ngā rerekētanga i roto i ngā raraunga gradient scalement, ka taea e ngā tohunga matawhenua te tautuhi i ngā wāhi pea mō te tūhuratanga atu.
Te Tūhuratanga Kohuke
Haunga te hinu me te hau, ka whakamahia hoki te FTG i roto i te tūhuratanga kohuke. Ko ngā rerekētanga o te mātotoru o te toka ka tohu pea i te aroaro o ētahi kohuke, pērā i te rino, te koura rānei. I roto i tēnei horopaki, ka whakaratohia e te FTG ngā raraunga taipitopito ake hei āwhina i te whakawhāiti i ngā rohe tūhuratanga me te whakaiti i ngā utu whakahaere.
Ngā Whakamahinga i roto i te Rangahau Matawhenua me te Whaipara Tangata
Kāore te tikanga FTG e herea noa ki te tūhuratanga rauemi taiao engari he nui hoki ngā painga kei roto i ngā mara o te matawhenua me te whaipara tangata. Mā te kaha ki te tautuhi taipitopito i ngā hanganga o raro whenua, ka taea te whakamahi i te FTG ki te mahere i ngā hapa matawhenua, te tautuhi i ngā āhuatanga matawhenua whakapae, tae atu ki te kimi i ngā wāhi whaipara tangata huna.
Ngā Akoranga Pūia
He mea nui anō hoki te mahi a ngā FTG i roto i ngā rangahau puia. Mā te aroturuki i ngā rerekētanga o te papa taumaha huri noa i te puia, ka taea e ngā kaipūtaiao te kite i ngā huringa o te mahi magma i raro i te mata. He mea nui tēnei mōhiohio mō te aromatawai i ngā pahūtanga pea me ngā mōrearea ki ngā hapori e karapoti ana.
Rangahau Whaipara Tangata
I roto i te whaipara tangata, ka taea te whakamahi i te FTG hei kimi i ngā toenga o ngā whare tawhito, o ngā wāhi rānei i tanumia ki raro i te whenua. Hei tauira, ka pā te hanganga o tētahi whare, o tētahi pakitara rānei ki te papa taumaha ā-rohe, ā, ka taea te kite i ēnei rerekētanga mā te FTG. Mā tēnei tikanga ka taea te ako i ngā wāhi whaipara tangata, kāore e hiahiatia he keri nui.
Ngā Painga me ngā Wero
Te Whakamutunga
1. Taumira Teitei: He tino teitei te taumira o te FTG ki te whakataurite ki ngā tikanga ā-papa tuku iho.
2. Te Whai Hua o te Wā me te Utu: Nā te mea ka taea te whakahaere i ngā rangahau FTG mai i te rangi, ka taea te kapi i ngā wāhi nunui i roto i te wā poto.
3. Raraunga Maha-Ahu: Me ngā wāhanga tensor e iwa, ka whakaratohia e te FTG he tirohanga whānui maha-ahu o te hanganga o raro i te mata.
Wero
1. Ngā Utu Taputapu: He tino utu nui ngā taputapu ine karātiōne e whakamahia ana i roto i te FTG.
2. Te Uaua o ngā Raraunga: He tino uaua ngā raraunga ka whakaputaina, ā, me tātari matatini mā te whakamahi i ngā pūmanawa motuhake.
3. Te Tairongo ki te Papa: He tino tairongo tēnei taputapu ki ngā pokanoa o waho, ā, he uaua ake ngā rangahau ā-rangi, inā koa i ngā āhuatanga kino o te rangi.
Whakamutunga
He tikanga matawhenua kaha, matatau hoki te Full Tensor Gradiometry (FTG) me ngā whakamahinga maha i roto i te tūhuratanga rauemi, te rangahau matawhenua, me te whaipara tangata. Ko tōna painga matua ki te whakarato raraunga taumira teitei, maha-ahu, he taputapu tino whai hua mō ngā kaipūtaiao me ngā miihini. Ahakoa kei te mau tonu ngā wero e pā ana ki te utu me te uaua o ngā raraunga, kei te haere tonu ngā whanaketanga hangarau ki te hanga i te FTG kia iti ake te utu me te whai hua. Nō reira, ka haere tonu te mahi a te FTG ki te mārama ake ki te hanganga o te Ao me tōna pūmanawa rauemi taiao.
