A machine selecting spherules from deep sea sediments

I am working on a machine that could select spherical micro particles from deep sea sediments. It is based on a inclined vibrating plane on which the spherical particles are rolling down. After a few adjustments it seems it works quite good. This picture is a sample of non magnetic particles selected by the machine. I think these spheres are from animal kingdom. Maybe eggs.

The drawback of the machine is it also discards many spherules. That would be unacceptable working on dust from urban roofs. But the deep sea sediments, even if difficult to recover, are virtually infinite. Once one find a way to recover deep sea sediments, discarding part of them should not be much problem.

Here is a good micrometeorite pretender I found using the machine for the first time on real unchecked sediments (it is translucid):


I also find this weird twin that is very probably terrestrial.


Opinions on the machine and on the micrometeorites pretenders are welcome.

Thanks,
Gauthier

Chloridric Acid for cleaning Calcium Carbonate deposits on micrometeorites candidates

Image
The particles I find in the sediments from the deep water sometimes look like "dirty". I wondered if this could be a layer of calcium carbonate. 1500 meters deep is quite above the Calcium Carbonate Compensation Depth (CCD). T he water is oversaturated in disolved calcium carbonate and this leads to a slow precipitation at the bottom. A possible solution would be cleaning the micrometeorites candidates with chloridric acid in low concentration. Fortunately the Calcium Carbonate reacts strongly with any acid and produces carbon  dioxide (gas) and dissolved calcium chloride. Here is a first attempt. I see part of the yellowish deposit is actually Calcium Carbonate but it is not only that. Between the strips of this possibly barred olivine micrometeorite, the yellowish/brownish color is apparently not Calcium Carbonate.

Group of terrestrial spherules

NOT GOOD ! This is probably the worst you can find while looking for micrometeorites. I found it in the deep sea sediments I recovered. Many micrometeorites have a spherical or aerodynamical shape (if they melted when entering the atmosphere). Most of them also show one or more metal beads. So finding a particle with spherical shape and metal bead is good. It should be good. But micrometeorites are singles. They were alone in space, they should remain alone on the earth. Finding a group of 2 or more micrometeorites means these are just not micrometeorites. I found this group of spherules with metal beads which would have been good candidates if they were alone. Y have no idea which terrestrial phenomenon on the earth produced these nice imposters . But this is disappointing as this reduces the probability other glassy candidates with a metal bead  I found  are extraterrestrial. The need of a (complex) chemical analysis is now higher.

News from -1500m

I am still working on the sediments I recovered from the deep sea bottom, at -1500 m deep. A few days ago I extracted some magnetic particles with a magnet, I look through the microscope and I saw quite a few interesting things. Today I took some pictures of the particles. Some particles, with spherical shapes are translucid but I could not show this on a picture. I need to improve my set up to do so. So I discarded the translucid ones and took pictures of others. Here they are. This one is a nice barred olivine Micrometeorite. It looks like MM 340 from the book "In the search of Stardust" by Jon Larsen. Notice it is surprisingly not weathered despite it is coming from the sea bottom. Unfortunately this one is probably not a Micrometeorite. First it is too big. The shape is too spherical. I cannot see any detail suggesting it is a MM. But there are very few spherical particles in the sediments I recovered, so it would be interesting to analyze this despite it does not actuall...
