Question

1. Match the rock feature (left column) with its possible depositional environment (right column). ____ Thin bedded shale a. Fluvial ____ Tan cross-bedded sandstone, rounded grains, well-sorted b. Lagoon or shallow sea with arid climate ____ Red beds with fining-upward sequences, asymmetrical ripples c. Carbonate tidal flat ____ Coal and siltstone with plant fossils d. Deep, quiet water offshore ____ Stromatolitic and intraclastic limestone e. Windblown

Answer 1

Answer:

a. Fluvial - Tan cross - bedded sandstone, rounded grains, well - sorted.

b. Lagoon or Shallow sea with arid climate - Thin bedded shale

c. Carbonate tidal flat - Laminated Evaporite minerals

d. Deep quite water offshore - Stromatolitic and intraclastic limestone.

e. Wind blown dessert - Red bed with fining-upward sequences, asymmetrical ripples

f. Delta swamp - Coal and siltstone with plant fossils -  

Explanation:

The geographic features of the rock area near the sea is different with the coastal sides. The lagoon is sea water which is not much deep and the water is shallow there. The red bed is the dessert where wind blows and the ripples are not symmetrical.
