It is a rather interesting and very useful paper. Webb also wrote; "Paul's response suggests that field work could be profitable if the site could be located. That took me by surprise; I assumed too much time had passed. It's an exciting thought." I agree with you that this is a very interesting thought. It the case of the reported falls that involve just a few stones, it highly unlikely that much of anything could be found. However, in case of certain reported falls, in which it appears that thousands of pieces might have fell, I think even after a few hundred years, that there is a fair chance that there might still be meteorites that can be found. I suspect, if a person took into account what geoarchaeologists call "site formation processes" and used what is known about the geomorphology and geomorphologic history of the area, a good geomorphologist / geologist / geoarchaeology could make specific predictions as to where any meteorites from a fall eventually came to rest and where to best look for them. It is matter of using the enormous amount of knowledge already gathered about geomorphology, surficial landscape processes, and "site formation processes" to predict the best places to look for meteorites deposited from a possible fall. Of course after several hundred years, any meteorites found would likely be too weathered to be of any interest to collectors. However, I suspect that scientifically useful information can still be collected despite how badly weathered the specimens might be. Of course, any search for such reported falls would not be easy and there would be no guarantee of success. Looking at Yau et al. (1994), the reported 1490 fall, in my opinion, might be a promising candidate for a search for meteorites because of both the reported number of objects and the reported size, 1.0 to 1.5 kg, of individual pieces. Unfortunately, at this time, I cannot determine what the modern name for Ch'ing-yang, China and its exact location is at this time given the different and changing ways that Chinese names have been and are transliterated into English.
