Stratigraphic boundary problems are an important component of describing the geology and stratigraphy of India.
Stratigraphic boundaries separate rocks of significantly different environments or lithology.
Stratigraphic boundaries are ideally defined by distinct lithological, geochemical, and palaeobiological signatures, to which a chronological framework can be applied.
Stratigraphic boundaries are determined by one or more of geological events such as
volcanic activity,
sedimentation,
tectonism,
paleo-environments &
evolution of life.
Faunal records have played a major role in determining the boundaries of the Phanerozoic units.
The other geological events are dated on the evidence of fossil records.
Boundary problems refer to the process of demarcating stratigraphic boundaries and addressing the challenges that may arise.
Marking sequence boundaries is not a straightforward exercise.
