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).

> Should we retain any?

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]:
