To assess kerogen quality visually, we can separate it from the mineral matrix through acidification. We can then examine the kerogen using transmitted light through a microscope to determine its form (structured or amorphous) and origin. Structured kerogens include woody, herbaceous, vitrinite, and inertinite. Amorphous kerogens are by far the most prevalent and include most of the algal material.
