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 ...

Nov 20, 2020 · The nakhlite source seems to have undergone variable degrees of metasomatism (=change in bulk composition due to introduction of fluids). Based on the calculated compositions of the nakhlite parental melt, the nakhlite and chassignite sources could have been enriched in K through metasomatism (Goodrich et al., 2013; Ostwald et al., 2020a).
May 3, 2019 · Image credit: NASA-JSC, ANSMET. A new study led by Anne Peslier (NASA Johnson Space Center, Houston) investigates the water contents and hydrogen isotope ratios of nakhlites, which are martian meteorites derived from volcanic lava or shallow intrusions in the planet’s crust.
