.................. is shallow diagensis stage occurring shortly after burial.
Answer: B
The shallow stage just after burial is Eodiagensis (eodiagenesis).
Choquette and Pray (1970) divided diagenesis into three stages: eodiagenesis, close to the surface where pore waters are still connected with the depositional environment; mesodiagenesis, during deeper burial; and telodiagenesis, when rocks are uplifted and exposed again to meteoric water.
Mesodiagenesis is therefore the deep stage and telodiagenesis the uplift stage. 'Paragensis' is not a diagenetic stage; paragenesis is the sequence in which minerals form.
