One) Based on the principles of stratigraphy and law of superposition, the deepest layer uncovered, U, is the oldest layer. This seems that this law can be generally applied to all of the layers with the exception of the wall in layers N through H.
For the law of strata identified by their contents, layers U through R seem related. I found it interesting that Strata J and L seem to be related even though they are separated by a cement floor. Also, how did that wall get so far underground? The right side of the wall seems to not follow the general pattern. The stratas may have been disturbed in some way.
Two) The right side of the wall seems to be mixed in some way. Evidence of collection seems to be present. Also I would count the burials as mixing and filling.
Three) The evidence of collection is found in all the layers on the right side of the wall. The pottery found is the only way to really see the difference in these layers. The pottery was similar to designs from older layers and less similar to the pottery found in layers to the left of the wall. The burials show mixing and filling because the order of the layers are disturbed.
Four) It seems a little hard to tell when the wall was built. Do the concrete floors mean layer N was some sort of underground basement, or was the entire thing built above or underground? There seems to be arguments for both sides. On one hand, the strata to the left have different pottery designs from the designs in the strata to the right. It might be possible that the strata on the left side of the wall was dug out as a house, burial chamber, or a mound of any kind.
Five) I think it is hard to draw a definitive conclusion of the ages of the strata on either side of the wall. I seems that I’ and J’ are related to N. I think it would be easier to tell if there was more information on what the wall and concrete floors actually are.
Six) O through H and I’ through H’
Seven) The sequence of burials for the excavations starts with the flexed burial pit in stratum Q and P. Then the second oldest is the extended burial of stratum C and B. Then shaft tomb dug from stratum A to D.
