Sol750_Spirit_Soil_Details

Growths and shaped patterns which appear in some to be recent or with original formed integrity, and, with other items, to be in a decayed or altered state, both types mixed in the soil co-existing.
To my understanding, many of the items are not geological in appearance, or may be fossils. Alternatively, they may all be mineral growths unique to Mars.
Observations, or other examples? Enlarged at 4X the original, details to be added.
These Spirit images appear nearly identical to Opportunity images.

The image section displayed as the topic entry is a small area of the darker soil in the central part of the original. It is enlarged at 4X, or 4096x4096 pixels, and has been increased in contrast, brightness, and gamma to show dark details. You should seek details in the originals to confirm my observations.

A description of the marked items in the closeup section, and a BMP of the section.

A dark fiber growth with a light toned ovoid tip-yellow at bottom.
A dark fiber growth with a light toned micro-spheroid tip-yellow at the center area.
A medium toned micro-spheroid with a long well formed thick tendril or fiber at the right side of the enlarged section above. The apparent connected tendril is masked by an obstruction and is seen angled to the center of the section. Marked in dark blue.
A series of micro-spheroids as a clump. This dark blue marked collection sits at the center of the section image. At the dark blue line, and extending toward the upper right area of the section is a multiple parted shape in light toned material which seems to be altered with the soil materials, and which may be older than the other marked items. The viewed 'shell-like' shaping matches some additional individual pieces around it.
An additional image slightly altered from the topic image, same coverage, in BMP at 1.5MB below.

I have tried two additional image hosting sites and found I have difficulty posting the uploaded image enlargements from the sites. I try to resolve that and report any new image hosting sites that seem to work eventually.
Below is an enlargement at 8X of a small light toned spheroid with a medium toned stem, a shadow cast from the stem at the base, and, a base which is integrated with the recess of the rock surface and alteration product around the base unit with a fissure between the features.
The object is enlarged to the visual limit of viewable sharpness and information, but it is very well shaped and identifiable as a single object. The fissure around the base is cleared of debris, the stem is free of debris, and the small micro-spheroid is also clear of debris. The angle of the stem, and whether the unit is free standing, or whether the spheroid is erect is not clear. At top it does not appear the spheroid is elevated above the rock, but it may be.
Again, this is 8X the full frame original, lightened and increased in contrast for viewing at this magnification. The far upper left section of the full frame.

An additional apparent light toned object appears attached to a darker stem on the top of the small mound at the right side of this enlargement as well, but it is much less certain a shape in 3D elevation in this image. From viewing many of these items it is clear that the spheres tend to be isolated and solitary structures, and the stems are singular in attachment to them as a rule. Attachment and orientation is axial generally.
.

A semitransparent spheroid or discoid shape with a distinct stem and a apical growth clump of loosely knit fibers in light tones is located at the rock/soil margin on the left of center area towards the top of the full frame image. The image details do not cast much shadow, and are very transparent.
This cropped section is at 4X, and is increased in contrast and gamma to show the periphery around both the light toned rock, and the darker soil particles.
Is this an aspect of the accumulation of the rock layered deposits, or a transient process, such as a living object? The shaping is rather well ordered and elaborate for a simple mineral sequence or a chemical compound crystalline structure, Is the complexity sufficient to determine a process item type identification?

Many similar transparent spheres have been present in photos returned from the rovers.

A large JPG of the upper section of the full frame NASA gallery image. As the focus plane was not aligned with the soil surface, this narrow top strip of the original is the only part of the image which is well focused. The left side of this strip is focused, and contains the items shown above. The right side of the image strip here is not well focused, but it does contain items of interest.
This is at 4X, adjusted for dark soil conditions, at 128 tones in grey scale.
