Los coleccionistas suelen encontrar meteoritos en desiertos o llanuras nevadas, donde sobresalen en el\u00a0paisaje \u00e1rido. Los cient\u00edficos pueden verificar que un meteorito es marciano al comparar\u00a0sus componentes minerales y qu\u00edmicos con\u00a0datos recopilados por las misiones de la NASA.\nIndicios de agua\nOtras investigaciones\u00a0ya hab\u00edan descrito este fragmento\u00a0gracias a\u00a0sus is\u00f3topos de ox\u00edgeno, que sirven como huellas geoqu\u00edmicas de los distintos cuerpos planetarios.\nEn este caso, los investigadores compararon los is\u00f3topos de ox\u00edgeno del meteorito con los observados en otros ejemplares\u00a0marcianos. Teghaza 001 parec\u00eda ser una shergottita, que es la clase m\u00e1s com\u00fan de meteorito procedente de\u00a0Marte. No obstante, \u00a0presenta\u00a0texturas extra\u00f1as y minerales inusuales que no se hab\u00edan visto antes.\u00a0\nCuando se obtuvieron los resultados de la dataci\u00f3n, los investigadores\u00a0se quedaron\u00a0sorprendidos. Esta\u00a0roca hab\u00eda sido alterada por\u00a0agua marciana hace unos 4 mil\u00a0millones de a\u00f1os, lo que sugiere que se form\u00f3 mucho antes. Las pistas que ofrecen los is\u00f3topos de ox\u00edgeno, la textura y la composici\u00f3n qu\u00edmica de los minerales de Teghaza 001 apuntan a un ciclo del agua mucho m\u00e1s din\u00e1mico en el Marte primitivo.\nReferencia:\nLiu.
