CLARIFICATION ON REPLY NO. 4 COMPARISON IMAGE AS INDICATIVE OF A POSSIBLE RELATIONSHIP BETWEEN EKWIR AND THE PLASTIC STRUCTURE
In Reply No. 4, I posted a comparison of the Plastic and Ekwir_1. Note the "nodule" in Ekwir. It seemed to me that the Plastic was propped in an upright position upon a small "mount" for lack of a better term at Rocknest. When I saw Ekwir, I observed the brushed part exposed a "mount" similar to that propping up the Plastic at Rocknest.
Note the "nodule" in Ekwir. It seems they're calling them "minibowls."
"Whereas nodules and concretions have been found elsewhere on Mars, to-date minibowls have been observed only at Yellowknife Bay. Mastcam, MAHLI, and ChemCam RMI data show that minibowls are similar in size to nodules, ranging from 0.6 to 5.6 mm in diameter, with mean diameter of 1.2 mm. The mean diameter of the minibowl depressions is 0.7 mm"
Source: "THE DISTRIBUTION AND ORIGIN OF NODULES AND MINIBOWLS WITHIN THE SHEEPBED MEMBER: IMPLICATIONS FOR EARLY DIAGENESIS IN YELLOWKNIFE BAY, GALE CRATER, MARS":
Here's a "minibowl" from Wernecke:
Note the size of the "Minibowls" are "from 0.6 to 5.6 mm in diameter, with mean diameter of 1.2 mm."
Recall, the Plastic was "1.3 centimeters" in size (or, 13 mm). The total length of the Plastic, then is slightly longer than the average "minibowl" size. I believe the "folded" looking middle part of the Plastic is the part actually sitting atop the "minibowl" or "mount." Here's a visual representation of my terms:
Now, refering back to the Reply No. 4 picture with the Plastic directly atop the "minibowl" mount:
Okay, so both the Plastic and the "minibowls" are diminutive in size. The "minibowls" only occur in one of two places on Mars known beyond doubt to be (1) habitable with (2) fresh, drinking water.
POSSIBLE RELATIONSHIP (FACTS):
1. The Plastic was observed at Rocknest, in the Glenelg region.
2. Yellowknife Bay is also in Glenelg, YARDS away from where they observed the Plastic.
3. "to-date minibowls have been observed only at Yellowknife Bay"
4. The Plastic and the "minibowls" are millimeters in size (both very small).
5. Yellowknife Bay's habitability is known beyond doubt, or as one might say an "astrobiologically relevant ancient environment"
POSSIBLE RELATIONSHIP (SPECULATION):
1. The cracks/dust clods that tend to transcend the Ekwir "minibowls" and "nodules" appear to be similarly patterned with the cracks tending to transcend various "pebbles" as well as the "mount" at Rocknest.
I speculate, then, that both the "pebbles" surrounding the Plastic at Rocknest, as well as the Plastic itself, fit perfectly in place ATOP the "minibowls" and "nodules," and are therefore related.
Or, as they would term it, "a potential biosignature" comprising "an object, substance and/or pattern that might have a biological origin and thus compels investigators to gather more data before reaching a conclusion as to the presence or absence of life."
