Which two chalk types are found in Champagne?

• A. Belemnite chalk and Micraster chalk
• B. Belemnite chalk
• C. Micraster chalk
• D. Chalk of the Champagne region

Answer: (A)

In Champagne geology, chalk is categorized by the fossils it contains, which helps identify distinct layers that influence soil character. The two main chalk varieties you’ll encounter there are Belemnite chalk, which is rich in fossil belemnites, and Micraster chalk, which contains abundant fossil echinoids of Micraster. These two chalk types are characteristic of the region and together define the specific chalky soils that affect drainage, mineral availability, and ultimately vineyard conditions. The other options don’t name both of these fossil-based chalk varieties, or they’re too generic about chalk in the region.
