Question 1

Characteristics of Braided Rivers

Answer 1

Mostly conglomerates and coarse sandstones; typically there is very little mud in braided stream deposits.

Example: Cross-bedding, horizontal lamination in channel deposits.

Question 2

Floodplain deposits in Braided Rivers

Answer 2

Floodplain deposits are rare due to constant channel migration.

Question 3

Characteristics of Meandering Rivers

Answer 3

Typically consist of sands and muds and some gravel; includes mudstone, sandstone, and some sandstone with conglomerate stringers.

Example: Usually channel-fill deposits (trough and planar cross-bedded sands and gravels) overlain by overbank deposits (laminated and/or bioturbated massive muds).

Question 4

Lateral accretion surfaces in Meandering Rivers

Answer 4

Present in the deposits of meandering rivers.
