My answer is a maybe.

There are a series of papers by Wu Siben from the 80s and 90s, like this one, that kind of assume it is a meteorite impact crater. The papers are pretty much all written by Mr. Wu and there seems to be little discussion of the question if it is an impact crater, it seems like he simply assumes it is one and then goes from there.

In contrast, there is this paper from 2017 by Xu et al. that clearly concludes that it is not an impact crater. Instead they found that the region is of volcanic origin. With the big ring structure perhaps being the remnant of an old volcanic caldera.

Personally, the 2017 paper seems much more solid than the old research by Wu. In particular the methods are much better.

Hard to tell for me, but I don’t think so.

It’s not circular and there isn’t raised land completely surrounding it.
