it does not look like plant remains.

Would you have a scale ?

Dear Marc

Photos taked with lens x4 or x10. Are there gastropod or ostracod?

Dear Ebrahim:

You have ostracodes, gastropods and possible coated algae. All of them are unidentifiable because first of all of the preservation, and second, they are in thin sections.

All the best,

Galina Nestell

Dear Mobin,

Before I go for any suggestions, please put mark on fossil(s) which you want to get information about them. secondly, always put scale on your micrographs, so one can get an idea about the size of fossil.

Now, on these micrographs, you have got lots of shell fragments, some ostracods, gastropods shell, some diatoms, possibly some silica remains of algae and some other staff which are not clear. Most of the shells have been filled up by sediments or replaced by calcite.

Please add sacle and mark fossils and take very clear micrographs again, then colleagues may give better suggestions.

with best wishes,

Habib. 

May be some pteropods too ...

But, the rock age would  not match.

Diatoms in the Carboniferous????

Tanks a lot for your answers

Im sorry for scale bar but photos have taken with lens x4 and x10.

Dear Habib the oldest certain fossil diatoms are Lower Cretaceous in age, while this deposits are Carboniferous.

Dear Galina I have some photos from forams, can you identify them?

Dear Mobin:

I will try. Please, send me the photos of foraminifers.

Galina

Dear Galina

Tanks

I will send to your emails.

Hello Ebrahim

You have  microfauna of different group  but there is great variation regarding age  see image no 6 containing Pteropods  and in 4 no image Larger benthic foraminifer. But again raise question ? Pteropods was not present in Carboniferous.. ...foraminifer may be some Fusulinids  .. which has  bearing with your quoted age.... but image is not very clear as well as preservation is not very good.. so say something more is very tough.

What is the magnification on these photos?

Dear Mobin,

In addition to other colleagues’ good suggestions, there is a pollen grain of Pinus tree in the picture #5. I have drawn a yellow circle around the pollen. Pine pollen is very widely distributed and its presence in your sample does not necessarily indicate that pine trees have grown in the vicinity of sampling place.

Your rock unit is equivalent to Ora and Harur formations in Iraqi Kurdistan therefore you can read and compare the fauna within your rock unit with those that occurs in both Carboniferous formations in neighboring area.

Please find the attached book.

Hi Sanjay Verma

Are you sure it is Pteropod?

Dear Gglenn Simpson

Photos have taken with lens x4 and x10.

All what you have in the pictures are typical fossils in Carboniferous limestones. Most of them are fragments of molusc shells. Some of them may be regarded as bivalves. Basically all bioclasts that show long recrystallised shells.Some others are gastropods, including that reagrded by somebody as a pinus pollen (the pinus pollen has an organic wall and the fragment shown in your picture is calcitic, recrystallised from aragonite). With those pictures we can not be sure on more precise identification of the bivalves and gastropods. I do not think that the gastropods belong to the group of Pteropods, becasue they are really rare in the fossil record (most of them lack mineralised Shell). You have also some ostracods (for instance in the picture 3). They usually show a better preserved shell than most moluscs, because they are mainly calcitic, not aragonitic. Some of them show a brown shell in this case.  

Dear Sergio Rodríguez

Tanks a lot

I agree with your comments.

This facies can be indicate a low energy environment such as lagoon setting.

Well, on the environment, some of the bioclasts are fragmented, so it is clear that there are some moments of middle or high energy in the environment, but it is only sporadic, because there is a large percentage of micrite (it means long quite periods). The chaotic distribution of the clasts indicate that those "energetic" moments ceased abruptly. The presence of the assemblage of gastropods, bivalves and ostracods and the absence of groups such as brachiopods, corals or echinoderrms is typical of anomalous salinity (gastropods, bivalves and ostracods have large range of adaptation to high and low salinities).

Dear Sergio Rodríguez 

Can we name this microfacies Bioclastic Packstone? or no?

It is intermediate between packstone and wackestone, but yes, it is basically a bioclastic packstone.
