(j) Causes and significance of coral bleaching.

Section B

Q2.

(a) Why was there less manganese ore deposition in the Archaean than that in the Proterozoic? Justify your answer in the light of changes in the atmospheric- hydrospheric conditions and ocean-water stratification.

(b) In a titanohematite ore mineral which mineral will migrate to weak planes of host mineral ? Discuss about different types of open-space filling textures.

Section B
