Identify this mortar, please!

I have recently cleaned the paving at the back of my house and although there was some motar breaking up in places, predictably now there is more!

This is how the paving now looks, (apologies for the pictures at 90degrees, they weren't before being uploaded)


Up close,


And a few areas like this, with some gaps not as deep but running almost the width of a stone.


Question being, what is the motar and how close a match can I get these days as id like to get it re-pointed / repaired. Considering the paving was laid 20-23 years ago I believe, its done well but now needs a little refresh.

Thanks,

Edit, should of course be mortar....!

Interesting, thanks all. Some more thinking required now perhaps!

Yes there looks to be some sharp or another small stone mix in the mortar, its been done really nicely. As suspected, getting a good match is likely near to impossible,
