They could also be mineral streams, though I suppose that does not preclude anything else, probably enhances it in some ways.

Interesting images! Good find. I wonder......... do you have any idea of the scale of the Mars images?
When this image was obtained, the focus motor count position was 14695. This number indicates the internal position of the MAHLI lens at the time the image was acquired. This count also tells whether the dust cover was open or closed. Values between 0 and 6000 mean the dust cover was closed; values between 12500 and 16000 occur when the cover is open. For close-up images, the motor count can in some cases be used to estimate the distance between the MAHLI lens and target. For example, in-focus images obtained with the dust cover open for which the lens was 2.5 cm from the target have a motor count near 15270. If the lens is 5 cm from the target, the motor count is near 14360; if 7 cm, 13980; 10 cm, 13635; 15 cm, 13325; 20 cm, 13155; 25 cm, 13050; 30 cm, 12970. These correspond to image scales, in micrometers per pixel, of about 16, 25, 32, 42, 60, 77, 95, and 113.
MSL drove another 44 meters on Sol 1414, into an area with larger blocks of bedrock. This looks like a good area to drill into the Murray Formation, so nearby targets were selected and we are planning a short drive to position the vehicle for drilling. But first, ChemCam and Mastcam will observe bedrock targets "Chibia" and "Dondo." Mastcam will also measure the dust in the atmosphere and take an image of the Sol 1414 ChemCam AEGIS target. Then the arm will be deployed for lots of contact science and standard images of the wheels. MAHLI will take pictures of Chibia before the DRT is used to brush it off, then take lots of stereo images of the brushed spot.

current life on mars is almost impossible due to whats in the weak atmosphere.

That image is of a location (dubbed "Chibia") where Curiosity used its Dust Removal Tool (DRT) in preparation for possible drilling. The swirly patterns are most likely from the metallic fibres on that tool.

Upon closer inspection ,the fibers do appear to be on the rock and above it, not embedded...

That image is of the brushed area, they are fibers on the rock, not in it. I can tell because pf the shadowing beneath some and others half in, half out of focus.
You said, 'shaded' and 'more faint'. But thanks for showing the whole picture this time.
Indeed thats what they are, brush marks and fibers from pre drilling, shout out to wildespace.
