I have deleted identification-request tag and added missing tags as mineralogy, petrology or sedimentology from questions that are related with **field or theorical geology** ([example][1]). Also questions about clouds and meteorology instrumentation to facilitate the deletion task. I have also sugest to retag fossils questions as fossils and paleontology.

Then if a "ban" is applied to every question that has the tag those questions will be saved (I still don't understand how is gonna this be solved).

I completed the review. 

The result is:

 1. **Questions retaged deleting id-request tag** (~60)
 2. **Questions taged with identification-request** (387):

 - Questions asking to identify his mineral or rock (387, [we are closing everyone][2], will be done in some days).

So we should not retain any of the 388 questions taged with identification request. They can be deleted or locked, but all question we want to retain were untaged.
 
I am for accepting fossils questions, but if you wish not to, you can see the rest of questions asking to identify a fossil on fossils tag, that has only 60 question in total. It does not represent a traffic trouble and fossils can be very commonly identified from morphology are my reasons.

I hoppe it is correct with the community feelings, facilitating the deletion and/or locking task. 

ps: @Gimelist and @Semidiurnal Simon. Today a good new. I typed "identify my rock" and we are no longer the first entrance. I guess the closed questions html code (250/388 naming id my rock/mineral) has had some interance with Google's spider and we are beginning to solve the problem.

[The first entrance is now USGS, where it is adviced what we should have adviced some time ago][4]:
