JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech III PETROLEUM EXPLORATION METHODS Previous Question Paper (May/June - 2019 - R15)
Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks.
PART - A
Write a short note on Biostratigraphic horizon (Biohorizon).
Answer
A Biohorizon is a stratigraphic surface or boundary representing a significant change in the fossil content of a sedimentary sequence. It marks the first appearance, last appearance, or a notable change in the abundance or diversity of a specific taxon, serving as a marker for correlation.
Write a short note on the zonule.
Answer
A zonule is the smallest unit of biostratigraphic classification, defined by the presence of a specific fossil assemblage or a single characteristic taxon. It represents a limited geographic or stratigraphic interval and is used for detailed local correlation within a larger biozone.
