FIG. 8. — Breccia texture in sinters from El Tatio and comparable texture in Home Plate silica rocks. (A) A fresh surface of El Tatio sinter breccia shows porosity and clasts that resemble those from (B) “Norma Luker,” a silica rock broken open or overturned by the rover's wheel (MI image, sol 1291, P2956). (C) The sandblasted and basalt sand-covered surface of another El Tatio sinter breccia resembles (D) “Nancy Warren,” a silica rock exposed to aeolian abrasion <1 m from Norma Luker (MI image, sol 1227, P2976). Arrows in (C) and (D) highlight similar emergent tabular clasts. Sunlight appears saturated in a portion of this otherwise shadowed scene. All images are at the same scale. MI, Microscopic Imager.
