The geological contact zone at Missoula in this cropped MAHLI mosaic.
 It appears that the lower unit (mudstone?) is not as resistant to erosion, when compared with the upper unit (coarse sandstone) at this location |

I used MS ICE, will try again and see if I can get it to stitch correctly.EDIT I was saved by the focused merged images that have since been down-linked, I hope these have been better stitched. Clicking the image will open the 1024x573 version.  If I am interpreting the thumbnails correctly they used 16 separate images to create each the focus merged products. It's the most I have ever noticed, normally we see 8. Thanks to Gerald for the MAHLI Rule. Full size (3801 x 2126) LINK |

QUOTE (PaulH51 @ Jun 30 2015, 05:29 AM) A small mosaic using 3 focus stacked MAHLI images of "Big Arm" using white LED lighting on sol 1028 (June 28, 2015)  The target is mentioned in this USGS Mission Update from Lauren Edgar : Sol 1030: Bumping to Missoula I don't know about the rest of you, but I found this MAHLI set of images to be rather extraordinary. Would a geologist care to comment on this? To my untrained eye, it appears to be rounded (stream-borne?) gravels deposited in what appears to be in a loosely sorted out-wash area. Obviously these gravels have been seen earlier in the MSL trip to Mt Sharp, but this appears to be another example, or am I wrong? |

A NavCam anaglyph from sol 1030
Worth a zoom or two for the wafer thin overhanging rocks. It's like they're in competition to see who can overhang the furthest before breaking off.  "Just...a.....little.......further!" |

It is not obvious to me that any erosion took place between the deposition of the different rock units. However, since the lower unit has substantial veining, and the upper unit does not, there would appear to be a significant change in deposition environment and probably a significant age difference. I love speculating geology from a 100 million kilometers away. |

If the veins are an indication of hydrofracturing then their termination could be due to a change in the lithology (mechanical properties) of the overlying layer. If so then there may have been no great time between the deposition of the two layers with the veining a product of a later event from a deeper reservoir. |
