Simple Stratigrahpic Concepts We Might Be Able To Put into an Explorable Explanation, in order

Superposition: oldest things on bottom: show age goes up as depth goes up as measured from top.
- How to show: Plot of depth vs. Age. Assume continuous deposition & no post-deposition tectonic movement.
Walters law 1: neighboring facies on a map are neighboring facies in a well log
- How to show: Demonstrate that facies next to one another on the map are the same neighboring facies in the well.
Walkers law 2: same as above, with demonstrated exception of when there is a lot of erosion.
- How to show: Demonstrate non-neighbors can be next to one another in well if there is erosion that takes out the facies that would have been between. Show erosion where missing facies would have been.
Relative vs. Absolute time are not 1to1: As most time not preserved.
- How to show:Plot preserved time vs. all time per facies part of GDE. Need ability to turn erosion, rate deposition, non-deposition on or off during some facies changes.
Unconformity, disconformity, confirmity, paraconformity
- How to show: add lines to the previous plots that label changes in preservation state.

How to put in code?

A 2D grid that represents a map surface of depositional environments. Each grid block represents a facies (or type of depositional environment) within an overall GDE (gross depositional environment) map. Initially, we'll just use a 1D array within the 2D grid for the GDE and move up and down in dip direction only.
Series of time points in an array. Holds the movement of the GDE map relative to the location of the well at each time point. We'll assume the GDE stays constant and just moves up or down dip.
Small arrays of 10 values, one array for each typical log shape pattern Log shapes include upwards coarsening, finding, serrated sand, block sand, shale, etc. Values go from 0 to 10. There are 10 values in each array.
Object that relates each facies type to the probability each log shape pattern will occur during deposition of that facies.There can be one or more log shapes per facies.
Object that relates each facies type & value of recent movement to the probability of deposition, non-deposition, or erosion.This will get recorded at each time step like movement amount, position, facies, and log shape. <= It is currently not implimented!

The basic idea...

The basic idea is that, there is a distribution of facies within a GDE map, over time the position of the map relative to the well changes and different facies can be deposited. Each facies can deposited one or more log shape pattern. Each time deposition occurs, a log shape pattern array is added to the well.

If there are 48 time steps, and each time step only deposits and deposits one log shape pattern array of 10 values, then the final well will be 480 units long.

Future Things to Add in

Erosion!
Erosion based on rate of GDE movement & over which facies.
More than just two log curve shapes per facies.
Interaction of GDE movement and a topographical surface that affects deposition or erosion given accommodation space?
Get in some real logs and try to create fake versions by twiddling with the knobs of our log creation machine?

Potentially additional Stratigraphic Concepts:

Group, formation, member, bed
Cyclostratigraphy
Sequence stratigraphy / sea-level rise & fall
Unconformity, Angular unconformity,Disconformity,Paraconformity,Nonconformity
Interpretation of depositional environments from rock record.
Asymmetry of Transgressive and\nRegressive Cycles
Lithologic vs. chronostratigraphic correlation surfaces
