General statistics

Giorgio Buccellati – June 2010

In A16 there is a total of 699 observed contacts between any two features. One will find the complete list in the depositional synopsis. They are subdivided as follows (listed in the order of the depositional verbs):

verbtotalpercent
1acuts9814%
1bintrudes20.3%
2aleans against0-
2brests on213%
3aabuts16624%
3bbonds142%
4acovers32847%
4boverlays345%
5acaps0-
5bsits in365%


The lion’s share is with the two verbs “to cover” (almost half of the occurrences) and “to abut” (almost one quarter), followed by “to cut” (almost 15%). There is also no “leaning against” (which is, in fact, hardly possible for a feature), nor any “capping.”
