==性質==
NWA 7034是擁有[[斑狀 (地質)|斑狀結構]]的火山[[角礫岩]]，並且包含有直徑達到5毫米的[[斜長石]]（[[中長石]]）和[[輝石]]（[[普通輝石]]和[[易變輝石]]）[[斑晶]]嵌在細顆粒的[[基质 (地质)|基質]]內。其他附屬礦物包含[[磷灰石|氯磷灰石]]、[[铬铁矿]]、[[针铁矿]]、[[钛铁矿]]、[[磁鐵礦]]、[[磁赤鐵礦]]、[[鹼性長石]]和[[黃鐵礦]]<ref name="agee2013" />。隕石內甚至包含了[[淬火]]後的[[岩漿]]組成的碎屑岩。其基質則是由細顆粒[[斜長石]]、[[輝石]]、各種氧化物礦物和痕量鐵硫化物組成<ref name="MetDB NWA 7034" />。整體化學成分顯示NWA 7034所含的水量是至今所發現的火星隕石中最高者<ref name="NASA-20130103" />。隕石中的水可能是來自於火星上曾經存在的海洋，而這個海洋可能在最後變成隕石的火山岩因為火山噴發而形成時仍存在<ref name="Space.com NWA 7034">{{cite web|title=Mars Meteorite May Be Missing Link to Red Planet's Past|url=http://www.space.com/19117-mars-meteorite-martian-missing-link.html|publisher=Space.com|accessdate=5 January 2013|archive-date=2013-07-03|archive-url=https://web.archive.org/web/20130703055900/http://www.space.com/19117-mars-meteorite-martian-missing-link.html|dead-url=no}}</ref>。

NWA 7034的年齡大約是20.89 ± 0.81億年，在地質年代上屬於[[火星地質#地質年代|亞馬遜紀]]早期。它是已發現的火星隕石中第二古老的<ref name="NASA-20130103" /><ref name=Independent>{{cite web| title='Black Beauty' rock is a 2 billion year old unique 'meteorite' from Mars, say scientists| url=http://www.independent.co.uk/news/science/black-beauty-rock-is-a-2-billion-year-old-unique-meteorite-from-mars-say-scientists-8438298.html| publisher=Independent| accessdate=5 January 2013| archive-date=2013-05-19| archive-url=https://web.archive.org/web/20130519101413/http://www.independent.co.uk/news/science/black-beauty-rock-is-a-2-billion-year-old-unique-meteorite-from-mars-say-scientists-8438298.html| dead-url=no}}</ref><ref name="Agee 2013">{{cite journal| last=Agee| first=C.
