This sample \u2013 called Askival after similar rocks from the Isle of Rhum in Scotland \u2013 formed from crystals settling\u00a0down through\u00a0or rising through a magma body. The light toned grains are a mineral called feldspar. One of the curious features about Askival is that it is very silica-rich suggesting that aqueous solutions altered the rock. Finally an impact in the martian ancient highlands must have excavated the samples from the crust and dropped them as impact ejecta onto the surface of Gale.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_461\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-461\" class=\"size-medium wp-image-461\" src=\"https:\/\/staffblogs.le.ac.uk\/mars\/files\/2018\/05\/Askival-RMI-300x281.jpg\" alt=\"Askival RMI\" width=\"300\" height=\"281\" srcset=\"https:\/\/staffblogs.le.ac.uk\/mars\/files\/2018\/05\/Askival-RMI-300x281.jpg 300w, https:\/\/staffblogs.le.ac.uk\/mars\/files\/2018\/05\/Askival-RMI.jpg 672w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-461\" class=\"wp-caption-text\">Askival cumulate from the deep martian crust.
