A 2017 study dated them to at least four different eruptions from 1416 ± 7 Ma to 1322 ± 10 Ma. It has been shown that the nakhlites were suffused with liquid water around 620 million years ago and that they were ejected from Mars around 10.75 million years ago by an asteroid impact. They fell to Earth within the last 10,000 years.
On 28 September 2018, a shallow, large earthquake struck in the neck of the Minahasa Peninsula, Indonesia, with its epicentre located in the mountainous Donggala Regency, Central Sulawesi. The magnitude 7.5 quake was located 70 km (43 mi) away from the provincial capital Palu and was felt as far away as Samarinda on East Kalimantan and also in ...
Aug 17, 2021 · Newly analysed titanomagnetite–ilmenite (Tim–Ilm) intergrowths from Martian nakhlite meteorite Northwest Africa (NWA) 5790 yielded crystallisation temperature up to 1032 °C and oxygen fugacity (fO2) up to ΔQFM + 1.6, notably higher than previous estimates for nakhlite magmas (temperature < 950 °C, fO2 = ΔQFM − 0.5 to ΔQFM + 1). To interpret how the magma was reduced from ΔQFM − 0 ...

Noble Gases in Martian Meteorites. Ulrich Ott, ... Susanne P. Schwenzer, in Volatiles in the Martian Crust, 2019 3.2.3 The “Fractionated Atmospheric” Component. The nakhlites, like the shergottites, show enhanced 129 Xe/ 132 Xe ratios, but at a lower 84 Kr/ 132 Kr; that is, in the 129 Xe/ 132 Xe versus 84 Kr/ 132 Xe plot of Fig. 3.3 they plot above the mixing line between Chassigny and ...
