TLDR
In this article , the authors show that vermiculite is widespread on the martian surface and perhaps a more common mineral on that planet than on Earth, and they also show that it is possible to identify vermiculate by remote sensing or in situ infrared spectroscopy alone.About:

TL;DR: In this article , an in-depth spectral analysis of clay-rich outcrops identified in northern Xanthe Terra (300°-320° E, 10°-20° N) was performed to constrain the mineralogy of the clay outcrop, map their strength and distribution throughout the region, and develop a better understanding of the geologic environment at circum-Chryse Planitia.

Facile Synthesis of Two-Dimensional Natural Vermiculite Films for High-Performance Solid-State Electrolytes
TL;DR: In this paper , a two-dimensional (2D) vermiculite film has been successfully prepared by self-assembling expanded vermiculate nanosheets, which exhibits excellent ionic conductivity of 0.310 S·cm−1 at 600 °C with low excitation energy.

Sources of Clay‐Rich Sediment in Eberswalde Crater, Mars With Implications for Biopreservation Potential
TL;DR: In this article , the Eberswalde basin was analyzed using topographic and hyperspectral data from multiple geographic regions, and it was shown that the smectites found within the Eberwalde deposit formed during the Noachian (i.e., >3.5 Ga) in the subsurface and are fluvial detritus transported during the Hesperian (e.g., 3.5-2.0 Ga).

Subsurface water and clay mineral formation during the early history of Mars

TL;DR: Clay minerals, recently discovered to be widespread in Mars’s Noachian terrains, indicate long-duration interaction between water and rock over 3.7 billion years ago, and available data indicate substantial Martian clay formation by hydrothermal groundwater circulation and a Noachia rock record dominated by evidence of subsurface waters.
