In [this question](https://earthscience.stackexchange.com/questions/10182/need-help-identifying) the OP asks identification for 4 samples.<br />
(Update: question has been removed by the OP. It contained 4 pictures and basically only asked 'Can anyone identify these?')

Should this be split into 4 questions?

Personally, I'm in favor. It would require more effort from the OP, maybe resulting in better questions.

The famous [A guide for asking “Identify this rock” questions?](https://earthscience.meta.stackexchange.com/questions/124/a-guide-for-asking-identify-this-rock-questions?rq=1) does not answer this.<br />
If the consensus here is 'yes', a remark should be added there.
