Enigmatic discoveries made by the Mars Rover
Opportunity at the Meridiani Planum landing site are
so-called 'blueberries spherules' [1]. They show
similarities to terrestrial tektites, and in addition,
strong spectral signature of hematite [1]. We assume
that the formation mechanism of 'blueberries' is
related to dense (rheo)ignimbrite currents, analogous
to the formation of Earth's tektites [2]. Taking into
account the Сoriolis force on Mars [3], a distal
ignimbrite volcano can a cause of 'blueberries'[4]. As
well as 'blueberries' on Mars, so-called 'red stones' in
the Ries crater are associated with mantle hematites
[4]. The double-layer ejecta and distinctions between
inner and outer suevites in the Ries crater can be
explained by blasts of anisotropic laminated mantle-
crust layers beneath SW Germany since the
lowermost Moldanubian Ostrong zone comprises [5]
ancient ignimbrites (it points to volcanic blasts in the
past). Thus, as in the Ries crater, double-layer ejecta
of Mars craters are most likely not impactites [4].
