Imayini ye-Luanchuan molybdenum isatshalaliswa kakhulu eDolobheni laseLengshui, Idolobha laseChitudian, Idolobha laseShimiao, kanye neDolobha laseTaowan esifundeni. Indawo yezimayini eyinhloko inezindawo ezintathu zezimayini eziwumgogodla: IMaquan Mining Area, iNannihu Mining Area, kanye neShangfanggou Mining Area. Ingqikithi yemithombo yensimbi yendawo yezimayini ifinyelela kumathani ayizigidi ezingu-2.06, ibekwe kuqala e-Asia neyesithathu emhlabeni. Kuyinsimu enkulu kakhulu ye-molybdenum ore ngaphakathi kweChina.
Ukusabalalisa kanye Nomsuka
I-genesis yokwakheka kwamadiphozithi amakhulu kakhulu e-molybdenum yile: uhlobo lungokwediphozithi ye-skarn porphyry yohlobo lwe-molybdenum. Itshe eliwumzali elenza insimbi lifana nalelo lamadiphozithi angama-25 e-East Qinling Dabie Mountains belt molybdenum mineralization belt.
(1) Isatshalaliswa phakathi kwebanga elingu-10km lendawo yokuxhumana ngaphandle kwesisekelo esikhulu segwadle endaweni enkulu;
(2) Kusatshalaliswa ezimpambanweni zamaphutha ajulile namaphutha esifunda;
(3) Isenzeko isitoko esincane se-rock, okuyi-rock mass eyinhlanganisela ehlukanisiwe enendawo esobala engu-0.12km2, encane engxenyeni engenhla futhi enkulu engxenyeni engezansi. Indawo yetshe elifihlekile engxenyeni ejulile inkulu kune-1km2;
(4) Itshe linesakhiwo esifana ne-porphyry, ne-potassium feldspar njengenhlobonhlobo ephezulu yokushisa kanye ne-quartz njengohlobo lwe-β: An=7-20, ikakhulukazi olwakhiwe ngamatshe e-plagioclase;
(5) Idwala eline-asidi eqinile elinenkomba ye-Rittman engu-2.58, eyingxenye yedwala elingashoni kakhulu elingene ochungechungeni lwe-calcium alkaline yohlobo oluvamile lwasePacific elineasidi ephezulu, i-potassium ephezulu, i-alkali ephezulu, ne-magnesium calcium ephansi. I-rock mass yenziwa amaminerali kalula ekujuleni kuka-15mg/kg, kodwa amasampula amaningi ane-Mo>50mg/kg, kanti amanye amasampula ane-Mo>300mg/kg;
(7) Isikhathi sokwakhiwa kwamadwala kanye nesikhathi sokumbiwa kwamaminerali yi-142 Ma, okungeye-Early and Middle Jurassic, kanye nesikhathi sokuqala nesaphakathi sase-Yanshan, okuyisikhathi esihle kakhulu sokwenza amaminerali.
