# Example Stratigraphic Architecture

## Introduction

    library(StratPal)

This vignette provides an overview over the example stratigraphic architecture provided with the `StratPal` package.

## Stratigraphic Context

The example data is taken from a synthetic carbonate platform simulated using CarboKitten.jl (Hidding et al. 2025). It emulates scenario A from Hohmann et al (2024), which was originally simulated in CarboCAT (Burgess 2013), and is characterized by a sinusoidal sea level curve and 2 long (> 0.5 Myr) hiatuses over the 2 Myr duration of the run.

## Dataset structure

The structure of the dataset is explained on the help pages, which is available using

    ?scenarioA

## Simulation settings

The full code to generate simulation data and visualizations is available here. The simulation was run over 2 Myr at steps of 1 kyr, with data extracted at 2, 4, 6, 8, 10, and 12 km from shore in the middle of the simulated platform. Three carbonate factories were used: euphotic, oligophotic, and aphotic:

Production profile of the three carbonate factories

The eustatic sea level curve is a combination of third and fifth order changes with an amplitude of 20 and 2 m and a period of 1 and 0.112 Myr:

For users interested in more details, we recommend inspecting the simulation source code (written in Julia).
