(1) Such conditions are commonly associated with deltaic sedimentation which along the Gulf Coast attain thicknesses of 50, 000 feet.

(2) Cheniers are generally related to the deltaic environment.

(3) Creating a sustainable deltaic system requires to reestablish the processes that originally created the landscape.

(4) The tidal flat, paludal and the deltaic plane paludal environments during the Taiyuan and Shanxi periods are most favorable for coal generation.

(5) Cuspate deltaic sands micro-facies, which formed at the time of powerful wave action, the continuity of marine distributary channel is bad, and distributes in cuspate shape.

(6) Through accurate description and dissection of deltaic front outcrops, 11 petrographic facies types are established.

(7) Front deltaic pinchout area, which mainly consists of large pinchout area, and disperses sporadic surface reservoir.

(8) Northern part is lake delta system, including deltaic frontal mouth bar, distal bar, sheet sand and predelta mud.

(9) Hydrocarbons may be trapped in anticlines draped over deeply - buried horsts in the pre - deltaic basement.

(10) Eocene through lower Oligocene lacustrine shales and Oligocene through lower Miocene lacustrine and deltaic coaly shales are the mature source rocks.

(11) The river discharged into the western part of the deltaic plain.

(12) A very large proportion of the world's sedimentary cover is composed of ancient deltaic deposits.

(13) The Permian in Huainan coalfield is a set of deltaic coastal deposition.

(14) The favourable reservoir sandstones in these gas pools may broadly be assigned to the deltaic front channel mouth bar, deltaic plain distributary channel bar and fluvial channel bar microfacies.
