There is not much information about this interesting place. As well as about the antiquity of China in general. I propose to briefly look and ask questions based on the available photographs and descriptions: who and how could have removed the rock and why they left just such traces of their activities in the form of huge megaliths.
The ancient quarry is located near the city of Nanking. According to official history, the last stone workings in this quarry are dated to the 15th century. Why the mining of the stone was stopped and why these huge megaliths were left - there are no answers.
There are three huge megaliths in two places in the quarry. Their approximate characteristics and comparison with the block in Baalbek are given. The quarry is located on Yanshan Mountain, which has a height of 140 m. Weights are thousands of tons each.

View from the height of the megaliths in the quarry. The rock of this quarry is limestone. Simple enough to handle. Probably formed by outcrops of underground mineral waters with admixtures of other minerals. Like in Pamukkale in Turkey.
On the walls in the quarry, traces of "scratching out" of the rock are visible. But the "stripes" are not parallel as in machining (from the cutter teeth), but chaotic. Therefore, historians do not see the riddle here: everything was cut down by hand. It is surprising that over the centuries these traces have not been "eaten" by erosion. This happens quickly in calcareous rocks.
The stone masses were separated from the base, but they did not finish the work. They quit, turned down the work, because it became clear that such masses cannot be moved entirely? Or something prevented the completion of the work? If the first, then why take on such work without calculating your capabilities?
As can be seen in the photo taken from above, a large volume of rock was selected in the quarry. But where is this volume of stone structures in the vicinity?
Researchers with LAI have calculated that only one part of the quarry will fit 13 approximate size of megaliths (comparable to one of those located there).
In the Xiaolin Mausoleum, statues from the same breed can be found. But in the sum of their volume, they have an incomparably smaller volume than the breed once chosen in the quarry. The numbers here clearly do not add up. It can be assumed that the building material was transported from the quarry far, hundreds of kilometers away.
A couple more photos to assess the scale of the development and ideas of the ancients. In general, there is no logic in cutting down huge megaliths, it is unclear how to move them and use these dimensions in buildings. The structure can also be built from smaller blocks. Yes, larger blocks can be laid in the base, like our FBS blocks. And higher is the scale of smaller piece material.
Apparently, they wanted to make a stele from one megalith in the Yangshan quarry (this is indicated by the length of the megalith). And the purpose of the others is not clear.

What conclusions or assumptions can I make? In line with his hypothesis that almost all stone workings were made in plastic rocks, then blocks in this quarry could be cut out both from clay or plasticine. If in the examples from Peru many researchers come to this conclusion, then what prevents them from making such a conclusion here? Geoconcrete exits from the bowels were all over the planet. The ruts in the limestone mineral tuffs are also confirmation of this.
Probably the entire volume of blocks (buildings) or rock is now under a layer of clay in the vicinity of the quarry. I think this is an antediluvian quarry. It was produced before the cataclysm (or between its stages). But the size of the megaliths prompts two thoughts: it was not done by people. There is no logic for people to engage in cutting out such large blocks. Or representatives from the late Chinese dynasties tried to move the remains of the breed from more ancient workings (in their ambitious plans). But they realized that nothing would work.
Like the Longyu Grottoes, the Yanshan Mountain Quarry is the result of some kind of large-scale ancient activity. Probably, this region was less affected by geotectonic processes and traces of such workings remained for viewing. It is a pity that historians are not engineers or technologists - they do not see questions in such stone quarries.
