During intra-meeting field trip, we had a look at the westward verging San Ramon fault, which causes uplift of the Cordillera (Farellones and Abanico Tertiary Fm, left pic), and shows evidence of recent activity (trench across Quaternary deposits, right pic)

In Argentina 🇦🇷, the activity of the Eastern and eastward verging front of the Andes is clear! You can spot it easily between the Quaternary and the folded Neogene (left pic) and in the Holocene fluvial deposits in the Mendoza region 🤩
