E ai ki te pūrongo a THE United States Geological Survey (2014), ko ngā rahui kua whakamanahia o te karāpeti maori o te ao he 130 miriona tana, i roto i ēnei, ko ngā rahui o Brazil he 58 miriona tana, ā, ko Haina he 55 miriona tana, koinei te mea nui rawa atu o te ao. I tēnei rā ka kōrero mātou ki a koe mō te tohatoha o ngā rauemi karāpeti maori o te ao: mai i te tohatoha o te karāpeti maori o te ao, ahakoa he maha ngā whenua kua kitea ngā kohuke karāpeti maori, engari kāore i te maha ngā putunga me te tauine motuhake e wātea ana mō te whakamahinga ahumahi, ko te nuinga kei Haina, Brazil, Īnia, Czech Republic, Mexico me ētahi atu whenua.
1. Haina
E ai ki ngā tatauranga a te Manatū Whenua me ngā Rauemi, i te mutunga o te tau 2014, ko ngā rahui o Haina mō te karāpeti tioata he 20 miriona tana, ā, ko ngā rahui kua tautuhia he tata ki te 220 miriona tana, e horahia ana i roto i ngā kawanatanga 20 me ngā rohe motuhake pērā i a Heilongjiang, Shandong, Mongolia o Roto me Sichuan, ko Shandong me Heilongjiang ngā rohe whakaputa matua. Ko ngā rahui o te karāpeti tioata i Haina he tata ki te 5 miriona tana, ā, ko ngā rahui kua tautuhia he tata ki te 35 miriona tana, e horahia ana i roto i ngā kawanatanga 9 me ngā rohe motuhake pērā i a Hunan, Mongolia o Roto me Jilin, ko Chenzhou i Hunan te wāhi e nui ana te karāpeti tioata.
2. Parahi
E ai ki te US Geological Survey, e 58 miriona tana o ngā rahui kōhatu karāpeti kei Brazil, ā, neke atu i te 36 miriona tana o ēnei he rahui kōhatu karāpeti maori. Ko ngā putunga kōhatu o Brazil kei ngā whenua o Minas Gerais me Bahia. Ko ngā putunga kōhatu karāpeti pai rawa atu kei Minas Gerais.
3. Īnia
E 11 miriona tana o ngā rahui karāpeti kei Īnia, ā, e 158 miriona tana o ngā rauemi. E toru ngā rohe o te konganuku karāpeti, ā, ko te konganuku karāpeti he uara whanaketanga ōhanga kei te horahia whānuitia ki Andhra Pradesh me Orissa.
4. te repupiripia o Czech
Ko te Czech Republic te whenua he nui rawa ngā rauemi karāpeti maramara i Ūropi. Ko ngā putunga karāpeti maramara kei te tonga o te kawanatanga o Czech me te ihirangi waro pumau o te 15%. Ko ngā putunga karāpeti maramara i te rohe o Moravia he waituhi moroitikiriata te nuinga me te ihirangi waro pumau o te 35%. 5. Mehiko Ko te konganuku karāpeti maramara e kitea ana i Mehiko he karāpeti moroitikiriata e horahia ana i ngā kawanatanga o Sonora me Oaxaca. Ko te waituhi karāpeti maramara hermosillo kua whakawhanakehia he 65%~85% te reka.
