Stenos Puzzle

 

the order is 316B254 

I know that 3 happened more recently than 1 because 3 is an intrustion and it cuts through 1

I know that 1 happens more recently than 6 because 1 is a layer on top of 6

I know that B is more recent than 2 because it is a fault and it is before before two because you can see that 2 is split in two pieces

I know that 2 is before 5 because 2 is an intrustion and it intrudes in through 5

I know that 5 is before 4 because you can see that if you shifted the fault back to the way it was at firs, 5 happened prior to 4 because it would be on top of 4.
