To help make their case, the researchers have contrasted Spirit’s study of “Home Plate” — a plateau of layered rocks that the robot explored during the early part of its third year on Mars — with features found within active hot spring/geyser discharge channels at a site in northern Chile called El Tatio.

The work has resulted in a provocative paper: “Silica deposits on Mars with features resembling hot spring biosignatures at El Tatio in Chile.” …
