Isi ni umunyamuryango wingenzi wibyuma byingenzi.Ubushinwa budasanzwe butanga ubutunzi buri hejuru kandi buturuka cyane cyane kuri Baiyun Obo, ubutunzi budasanzwe-bunini budasanzwe ku isi.Nyamara, kubera imbogamizi zintego zubushakashatsi bwubucukuzi bwamabuye y'agaciro, inyigisho zidasanzwe zubutaka bwubutaka hamwe nubuhanga bwubushakashatsi, habayeho gusobanukirwa gutandukanye nuburyo bukomeye bwo gutunganya ibyuma, ubutare bwimibiri yimiterere yimiterere nubutunzi bushobora kubuza gusuzuma no gukoresha neza umutungo wubutaka budasanzwe. .Mu rwego rwo gusobanura uburyo bwo gushinga ububiko bwa Bayan Obo no gusuzuma umutungo ushobora kuba ku isi idasanzwe, Ikigo cya Jewoloji na Geofiziki cyo mu Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa cyohereje imishinga y’ingenzi kandi gifatanya na Baotou Iron and Steel (Group) Co., Ltd . hamwe n’ibice biyishamikiyeho gukora ubushakashatsi burambuye bwa geologiya mu karere, gusubiramo ikarita ya geologiya 1: 5000, uburyo bwinshi nubushakashatsi bunini bwa geofiziki nubushakashatsi bwa metallogeneque muri Bayan Obo.Binyuze mu bushakashatsi bwakozwe kuri geologiya, geochemie, geofiziki n’ubundi bumenyi, hagaragaye inzira y’ubwihindurize ya magma ya Bayan Obo carboneatite n’uburyo bwo gutungisha isi idasanzwe, uburyo bwo gutunganya karubone n’ibintu byo kugenzura amabuye y'agaciro byasobanuwe, bitatu- Imiterere yuburinganire bwamabuye yubutaka bwa geologiya yarubatswe, kandi umutungo wisi udasanzwe wongeye gusuzumwa.(1) Agace ka Baiyunebo kahuye ningendo nyinshi za tectonic.Mbere yo gutunganya amabuye ya karubone, amabuye yo hagati ya Proterozoic yo hagati-hagati (itsinda rya Baiyunebo quartz sandstone, conglomerate, plate, nibindi) mu bucukuzi bw'amabuye y'agaciro yakorewe ibikorwa byo guhagarika akarere ka tectonic, kandi ibice bitambitse byasimbuwe n'inzego kugirango bibe amabuye. imiterere ya cake, mylonite, ikubye, nibindi. Ibishya bishya bigizwe na EW bigenda byiyongera hamwe na sisitemu ya tectonic ihanamye itanga umuyoboro mwiza wo kuzamura magma ya karubone yimyaka ~ miliyari 1.3 (Ishusho 1).Ikwirakwizwa, ibiranga nubusabane hagati yubukererwe nubukererwe bwibitare byimitsi yo mumatsinda yo hagati ya Proterozoic Baiyunebo mumatsinda yubucukuzi bw'amabuye y'agaciro bigomba kongera gusuzumwa.
Igishushanyo 1 Amateka yiterambere hamwe no gutunganya karubone yo mu kibaya cya Mesoproterozoic Bayan Obo
.Urutare rwa Carbone ni urutare rwibanze rwo kwangiza isi kandi nubutaka budasanzwe bwubutaka.Ikusanyirizo ry'ibyuma binini muri Bayan Obo ryabaye mu myaka ~ miliyari 1,3.Magma ya karubone ifite ubwihindurize buva kuri fer-magnesium-calcareous, kandi ibintu bidasanzwe byubutaka biri mu bitare bya karubone mu byiciro bitandukanye, cyane cyane ibintu bidasanzwe by’ubutaka bidasanzwe, byerekana inzira yo gukungahaza buhoro buhoro.Nyuma yo gushinga amafaranga, habaye impinduka ebyiri muri Paleozoic Yambere (miriyoni 450 ~ 400) na Late Paleozoic (280 ~ 260 million).Inzira yo guhinduka yatumye isi idasanzwe no gukora amabuye y'agaciro mashya, ariko ntihariho kwiyongera kwisi kwisi idasanzwe.
.Amabuye nyamukuru hamwe nubutare bwiburasirazuba nigice cyingenzi cyo gukwirakwiza umubiri wa magneti.Amabuye y'ingenzi hamwe n'ubutare bw'iburasirazuba bihujwe no gukwirakwiza amabuye ya karubone, kandi ubujyakuzimu bw'iterambere bw'amabuye ya karubone ni manini.Umubiri muremure wa magnetiki anomaly hamwe numubiri muto udashobora kwihanganira umubiri ugaragaza ikwirakwizwa ryibice bitatu byurutare rwa karubone (umubiri wamabuye) (Ishusho 2).Carboneite muri Bayan Obo ifite ikigo cyo gutunganya kandi yishimira umuyoboro umwe wa magma mubice byimbitse.Hagati iherereye hagati yubutare bukuru nubutare bwiburasirazuba.Nyuma yo gutunganya magma ya karubone, amababi maremare yakozwe no gusimbuza imiterere yambere asunikwa muburengerazuba (ikirombe cyiburengerazuba) no muburasirazuba (Huahua), kandi gutandukana no guhuza bishobora kubaho (Ishusho 3).
Igishushanyo cya 3 Ikwirakwizwa rya karubone mu bubiko bwa Baiyunebo
.Ukurikije ikwirakwizwa ryabonetse, ingano nubunini (byibuze) ubwinshi bwurutare rwa karubone (umubiri wubutaka budasanzwe), hamwe no gukoresha 2% byubutaka budasanzwe bwibuye ryurutare rwose rwa karubone (hashingiwe ku gaciro kagereranijwe kagereranijwe kavuye mumibare mu myaka yashize), byagereranijwe ko umutungo ushobora kuba mwinshi wa oxyde yisi idasanzwe mu bucukuzi bwa Baiyunebo ari toni miliyoni 333, ibyo bikaba bikubye hafi inshuro 10 agaciro kamaze kumenyekana kuri toni miliyoni 36 muri Baiyunebo, Isi yose iherutse gusohoka byagaragaye ko ari isi idasanzwe. umutungo (harimo na Bayan Obo) n’ubushakashatsi bw’imiterere y’Amerika muri Amerika ni inshuro 2,78 za toni miliyoni 120.
