ʻIke ʻia ke aniani 12,000 makahiki o ka honua ma ka ʻāina ʻo ʻAmelika Hema, ua hoʻoholo ʻia ka mea pohihihi o ke kumu.

I ka wā ma mua, ua hoʻohana ʻia nā puka aniani pepa ma ka Kina kahiko a ʻo nā puka aniani i kēia manawa wale nō, e hana ana i nā paia aniani o nā kūlanakauhale i mea nani, akā ua ʻike ʻia nā aniani he ʻumi kaukani makahiki ma ka honua, aia ma kahi alahele 75 kilomika. ma ka wao nahele ʻo Atacama ma ka ʻāina ʻākau o ʻAmelika Hema ʻo Chile.Hoʻopuehu ʻia nā waihona aniani silicate ʻeleʻele ma ia wahi a ua hoʻāʻo ʻia e hōʻike i ko lākou noho ʻana ma laila no 12,000 mau makahiki, ma mua o ka hana ʻana o ke kanaka i ka ʻenehana hana aniani.Ua manaʻo ʻia kahi i loaʻa mai ai kēia mau mea aniani, no ka mea, ʻo ka wela wela wale nō ka mea e puhi ai i ka lepo one i nā kristal silicate, e alakaʻi ana kekahi i ka manaʻo ua hana ʻia nā "ahi gehena" ma ʻaneʻi.ʻO kahi noiʻi hou i alakaʻi ʻia e Brown University's Department of Earth, Environmental and Planetary Sciences e hōʻike ana ua hana ʻia ke aniani e ka wela koke o kahi comet kahiko i pahū ma luna o ka ʻili, e like me ka hōʻike Yahoo News ma ka lā 5 Nowemapa.ʻO ia hoʻi, ua hoʻoholo ʻia ka pohihihi o ke kumu o ke aniani kahiko.

Ma ke aʻo ʻana o ke Kulanui ʻo Brown, i paʻi ʻia i loko o ka puke pai Geology, ʻōlelo nā mea noiʻi he mau ʻāpana liʻiliʻi i loaʻa ʻole i kēia manawa ma ka Honua.A pili pono nā minerala i ka haku mele ʻana o nā mea i hoʻihoʻi ʻia mai i ka Honua e ka huakaʻi Stardust a NASA, nāna i hōʻiliʻili i nā ʻāpana mai kahi comet i kapa ʻia ʻo Wild 2. Ua hoʻoholo ka hui, me ka hui pū ʻana me nā haʻawina ʻē aʻe, ʻo kēia mau hōʻuluʻulu mineral paha ka hopena o kahi ʻO ka comet me kahi haku mele e like me Wild 2 e pahū ana ma kahi kokoke i ka Honua, me nā ʻāpana e hāʻule wikiwiki ana i ka wao nahele ʻo Atacama, e hoʻohua koke ana i nā wela kiʻekiʻe loa a hoʻoheheʻe i ka ʻili one, ʻoiai e waiho ana i kekahi o kāna mau mea ponoʻī.

Aia kēia mau kino aniani i ka wao nahele ʻo Atacama ma ka hikina o Kili, he pāpū ma ka ʻākau o Chile i palena ʻia e nā Andes i ka hikina a me nā mauna kahakai ʻo Chile ma ke komohana.I ka loaʻa ʻole o nā mea hōʻike no ka lua pele ʻino, ʻo ka genesis o ke aniani ua huki mau i ke kaiāulu geological a me geophysical i kahi no nā noiʻi pili.
