Stromatolite Thin Sections

Below are pictures of Stromatolites I have captured via microscope and camera.    I have found all fossils shown on this site on my 5.5 acre property in southern Oregon.  All pictures are approximately 100X normal size unless otherwise designated.   I have taken thin sections of approximately 750 rocks for viewing.   Only a few of these are shown below thank goodness.

The pictures you are viewing are of algae (Cyanobacteria or blue-green algae) and are preserved in Chert, Jasper, Jaspagate and other Silicon dioxide (SiO2) based rocks.   In reality, Stromatolites are what is called “Trace Fossils” since they have been replaced with minerals yet retain the original structure.   I usually bring the subject into view via layering so you can view it easier.   Chert is sometimes very difficult to shoot into due to its fine grain and reflective quality, so you will notice spots of light on the pictures.   Jasper, since it is opaque, makes it easier to take microscopic pictures.

I try not to duplicate similar photographs to keep things interesting.    It has to be something that really catches my attention and is different from other things for me to photograph it.   Many of the pictures below show fossil material in various areas of the Stromatolite rock.   In other words, I do not just take pictures of the laminations.

This has caused me many problems in the past.   I have always asked what the “Experts” wanted to see/view in the rocks, yet they never told me.   They never once stated they wanted to view only the laminations and peaks.   They would say what I had was not a Stromatolite, but that was it.   I was under the assumption that “Experts” knew the basic structure of stroms, and they don’t.   They don’t specialize in this type of fossil, and they haven’t spent months looking at them under a scope as I have.   I honestly think this was a game they were playing with a naïve engineer, and this is the first time I have stated this.   This game has gone on for over three years when it comes to absolutely ever variety of fossil I have presented.

  1. R/Sir,
    It is very interesting and very helpful for me. I am MS research scholar of geology in National Centre of Excellence in Geology, University of Peshawar. Sir I am doing research work mosozoic carbonates if there are any other stromatolites thin sections then please share with me.

  2. Hi,
    I work at a community college in Tacoma, WA. We have a fossils class and need a prepared slide. We would like to get a stromatolite thin section with fossil cells from the Precambrian (ideally). Can you meet this need or do you know a vender who can?
    Thank you,
    Lora

    1. Hi Lora,
      That’s wonderful you are doing that, and I only wish that Oregon would do the same. No one here, except me, seems to have any interest in Stroms. I have verification from Dr. Bruce Stinchcomb (St. Louis MO) that I have Stromatolites, but he won’t go so far as to say they are Precambrian. As you realize, we are supposed to have only Cambrian Era rocks in southern Oregon. I believe we also have some Precambrian.

      If you send me your information, I will mail you some verified Precambrian Stroms from elsewhere, and some of my finds. I will clearly mark them. They are beautiful under the scope. I would like to do it for no cost. My e-mail is kathylynndean@oigp.net Best wishes…Kathy
