I-artifact encane kakhulu eyakhiwe ngensimbi eyawa isuka esibhakabhakeni yalandwa eduze nendawo yokuhlala. Kwakungeyona i-meteorite eseduze kakhulu kule ndawo, nokho, abacwaningi bacabanga ukuthi kungenzeka ukuthi yavela e-Estonia, okuyibanga elide kakhulu.
Umcibisholo awubonisi nje kuphela ukusetshenziswa kwensimbi yesibhakabhaka esikhathini sangaphambi kokuncibilika, kodwa futhi uveza ubukhona bezinhlelo zokuhweba ezinkulu ezazisebenza ezinkulungwaneni zeminyaka edlule.
Isazi sokuma komhlaba u-Beda Hofmann we-Natural History Museum of Bern kanye neYunivesithi yaseBern eSwitzerland saqala uphenyo olunzulu ukuze sithole izinto zakudala zensimbi ye-meteoritic. Njengoba insimbi emsulwa yayiyivelakancane ezikhathini zasendulo, okuwukuphela kwendlela eyayitholakala kalula kwakuwukusebenzisa insimbi eyayiwe esibhakabhakeni isesimweni sama- meteorite.
I-iron meteorite uhlobo oluvame ukubonakala. Angakwazi ukusinda emthelela wokungena emkhathini futhi ngokuvamile akhiwe ngensimbi, kanye nenani elincane le-nickel kanye namanani amancane wezinye izinsimbi. Kukholakala ukuthi amathuluzi amaningi ensimbi nezikhali ezasetshenziswa ngesikhathi seBronze Age zadalwa kusetshenziswa insimbi ye-meteoritic.
Kuyo yonke iMpumalanga Ephakathi, eGibhithe nase-Asia, kuye kwatholakala izinto zobuciko eziningi; nokho, kube nokuncane kakhulu okutholakele kulo lonke elaseYurophu.
I-Morigen, etholakala eSwitzerland yanamuhla, yayiyindawo yokuhlala ephumelelayo ngesikhathi seBronze Age, kusukela cishe kuma-800 kuya ku-900 BCE. Insimu yaseTwannberg, equkethe izinsalela zedwala elafika livela ezulwini eminyakeni eminingi kakhulu ngaphambi kwesikhathi sokugcina seqhwa, laliqhelelene neMorigen (akukho ngaphezu kwamakhilomitha angu-8, noma amamayela angu-5) ngokusho kwe I-Harvard University abstract.
U-Hofmann nethimba lakhe bathola umcibisholo wensimbi endaweni ababevele beyigubhile. Yayingu-39.3 mm ubude futhi inesisindo esingu-2.904 amagremu. Iqembu laqaphela ukuthi kwakukhona izinsalela zezinto eziphilayo, elalicabanga ukuthi itiyela le-birch, okungenzeka lalisetshenziselwa ukunamathisela isihloko somcibisholo ku-shaft walo. Ukwakheka kwawo kwakungaveli kulo mhlaba.
Ukuhlaziywa kwento kuqinisekisile ukuba khona kwensimbi ne-nickel, okuwukwakheka okuvamile kwe-meteoritic iron. Ukwengeza, i-isotope ye-radioactive ye-aluminium - i-aluminium-26 - itholwe, engadalwa kuphela emkhathini, phakathi kwezinkanyezi.
Kuyathakazelisa kakhulu ukuqaphela ukuthi inhlanganisela yezinsimbi ezikhona kumcibisholo ayifani nensimbi etholakala e-Twannberg. Kunalokho, kubonakala kuwuhlobo lwe- iron meteorite eyaziwa ngokuthi i- I-IAB meteorites.
Imvelaphi yesihloko somcibisholo kulula ukuyibona uma kucatshangelwa ama-meteorite e-IAB amakhulu aziwa ukuthi aphahlazekile e-Europe. Okuthathu kwalokhu kunokwakheka okuhambisana nomcibisholo: Bohumilitz kusuka eCzechia, I-Retuerte de Bullaque kusuka eSpain, futhi Kaalijarv kusukela e-Estonia. Lawa ma-meteorite abhalwe kumawebhusayithi e-Lunar and Planetary Institute.
Abacwaningi baphethe ngokuthi u-Kaalijarv cishe wayehambisana nencazelo. Yase ifike eMhlabeni cishe ngo-1500 BCE futhi izingcezu eyazenza zazifaneleka ukwakhiwa zibe imicibisholo. Kodwa-ke, indawo yayo yayiqhele ngamakhilomitha angu-1600 (994 miles) ukusuka e-Morigen, okubonisa ukuthi kungenzeka ukuthi yahamba ngomgwaqo. Amber Road.
Uma kucatshangelwa inani elikhulu lemfucumfucu ye-meteorite edalwe imithelela ye-Kaalijarv, kungaba yinzuzo ukuhlola ngokuqoqwa kwezinto ezihambisana nomcibisholo, ngomzamo wokuthola i-meteorite engumzali.
Abacwaningi bathi nakuba kungenzeka ukuthi yavela eKaalijarv, kungenzeka kakhulu ukuthi umcibisholo wawungeyona into eyedwa futhi kungase kube nezinye izingcezu zensimbi ye-meteoritic esetshenziwe, njengalezo ezinosayizi omncane, emaqoqweni emivubukulo azungeze iYurophu futhi ngokunokwenzeka. nakakhulu.
Ucwaningo lwashicilelwa ekuqaleni kujenali Isayensi ngqo ngoJulayi 25, i-2023.
