The work is to study the interrelationships of the formations and structures portrayed in the cross section and unravel the order in which they logically occurred. Each formation and structure is assigned a letter of the alphabet as an identifier. Relative age concepts such as the Law of original Superposition, Principle of Inclusions, cross-cutting relationships, etc... and logic should guide the sequencing. Instructions:  present the order of events as letters from oldest to youngest in a single line.

(Ignore smaller letters. Instructor remade assignment with bigger letters to be more clear. Along with the solution, I'd appreciate an explanation of how it was found, but that is not necessary. I'm going to do it on my own, and will use the answer as a guide.)
