Kare, mahwindo emapepa aishandiswa muChina yekare uye mahwindo egirazi angori emazuva ano, zvichiita kuti madziro egirazi emaguta ave chiono chakanaka, asi makumi ezviuru zvemakore ekare magirazi akawanikwawo pasi pano, mumukoto we75 km. muRenje reAtacama kuchamhembe kweSouth America nyika yeChile.Madhipoziti egirazi rakasviba silicate akapararira munzvimbo uye akaedzwa kuratidza kuti anga aripo kwemakore gumi nemaviri, vanhu vasati vagadzira tekinoroji yekugadzira magirazi.Pave paine fungidziro yekuti zvinhu zvegirazi izvi zvakabva kupi, sezvo kupisa kwakanyanya chete kungadai kwakapisa ivhu rejecha kuita silicate crystals, zvichiita kuti vamwe vataure kuti "moto wegehena" wakamboitika pano.Ongororo ichangoburwa inotungamirwa neBrown University's Dhipatimendi rePasi, Environmental uye Planetary Sayenzi inoratidza kuti girazi rinogona kunge rakaumbwa nekupisa kwekukurumidza kwekometi yekare yakaputika pamusoro pepamusoro, sekureva kweYahoo News mushumo we5 Mbudzi.Mune mamwe mazwi, chakavanzika chekwakabva girazi rekare chakagadziriswa.
Muchidzidzo cheBrown University, ichangobva kuburitswa mupepanhau reGeology, vaongorori vanoti sampuli dzegirazi remugwenga dzine zvimedu zvidiki zvisingawanikwe paNyika.Uye zvicherwa zvakanyatsoenderana nekuumbwa kwezvinhu zvakadzoserwa kuNyika neNASA's Stardust mission, iyo yakaunganidza zvimedu kubva kucomet inonzi Wild 2. Chikwata ichi chakagumisa, pamwe chete nezvimwe zvidzidzo, kuti aya mamineral assemblages angangove mhedzisiro ye comet ine chimiro chakafanana neWild 2 inoputika panzvimbo iri padyo nePasi, iine zvikamu zvinowira nekukurumidza muAtacama Desert, ichibva yagadzira kupisa kwakanyanya uye nekunyungudutsa pasi pejecha, ichisiya zvimwe zvayo.
Iyi mitumbi yegirazi yakanamirwa paAtacama Desert kumabvazuva kweChile, bani riri kuchamhembe kweChile rakaganhurwa neAndes kumabvazuva uye Chilean Coastal Mountains kumadokero.Mukushaikwa kwehumbowo hwemhirizhonga ine kuputika kwegomo rinoputika, genesis yegirazi yagara ichikwezva nharaunda ye geological uye geophysical munharaunda kuti ienderere mberi neongororo.
