Any ideas as to what might have caused this?

Hi guys - as a bit of background the car in the photo is a 2018 Porsche Macan Turbo (Agate Grey). Today I managed to get out and give it a mini detail to get it ready for some road trips coming up over the summer and the recent heatwave has covered the car in pollen and dust.
The paint was washed how I'd usually approach it (rinse, wash with ph neutral soap, 2 buckets etc.) and when drying I noticed the black, almost tar like deposits on the paint (first photo) - but very specifically only on the boot lid. 10 minutes of claying had all the deposits off but the second photo of the absolutely filthy clay is after literally one pass on the paint.
Does anyone have any idea what might have caused this? the car is kept outside but isn't under any trees or anything that would usually leave deposits to this extent. I can't work out for the life of me what it might be - during the winter the car was driven to the French Alps through some pretty heavy snow but that seems like a red herring.
Any ideas welcome!

This just looks like an accumulation of tar spots to me, also why the clay has gone brown.
The air flow over the back of a Macan means everything gets sucked backwards and thus sticks to the tailgate and rear bumper.
If the car hasn't had any form of decon since before the winter, especially with European road trip mileage I'd say this was normal.
You may also find some tar along the inner wheel arch lips.
Driving on a freshly tarmac'd road can leave tar behind but this would normally be larger spots.

I was thinking that the not insubstantial diffuser on the Macan would encourage road debris right up onto the rear of the car, glad to get a second opinion from someone who knows what they're doing.
Some great stuff on the website by the way, love the work!

No worries, for future tar removal I'd recommend some tar remover as opposed to a clay-bar.I was thinking that the not insubstantial diffuser on the Macan would encourage road debris right up onto the rear of the car, glad to get a second opinion from someone who knows what they're doing.
