| The coastal lagoonal deposits are represented by bauxitic claystones resting on the undulating top of thick-bedded limestones. |
|
| Area 1: The Boundary Lake Member consists of tidal flat and lagoonal limestone and dolomites. |
|
| These carbonates are commonly flanked on the inner shelf by lagoonal shale and nearshore sandstone deposits. |
|
| Based upon the presence of calcareous algae, benthic foraminifera and nudists, a lagoonal environment has been suggested for the upper part of the Ocozocuautla Formation. |
|
| Here, specimens of the shallow subtidal-intertidal cockle Katelysia rhytiphora have moved up profile from lagoonal facies into advancing aeolian dune sediments. |
|
| Eurypterid associations can often be distinguished and related to environmental conditions, such as marine, lagoonal or estuarine, or brackish to freshwater faunas. |
|
| The field is in foreslope, reef margin and reef interior lagoonal facies of an atoll-type reef which built up to 150 metres above a regional limestone platform. |
|
| Thus, an atoll or annular reef may develop along the rim around the low-lying central region, which becomes a lagoon, and coral knolls grow on former pinnacles in the lagoonal area. |
|
| Many lagoonal lakes occur along low coastlines. |
|
| In all these lagoonal settlements the characteristic plan, still detectable in the street patterns, was dominated by a navigable channel from which side channels branched at intervals. |
|
| The middle unit, the Agbada Fm, is up to 4,600 metres thick locally and consists of shallower water marine sands and lagoonal sands and shales. |
|
| Sedimentary structures such as horizontal bedding, ripple bedding and rhythmic bedding are well developed, indicating a lagoonal environment. |
|
| The middle unit, the Agbada Fm, is up to 4,600 metres thick and consists of shallower-water marine sands and lagoonal sands and shales. |
|
| Patterns of lagoonal bivalve mortality after heavy sedimentation and their paleoecological significance. |
|
| Such dynamic lagoonal systems are a product of the Mediterranean climate that characterizes California. |
|
| The features of these facies indicate the moderate to high energy shallow water conditions such as inner shelf lagoonal environment. |
|
| The Quaternary alluvial deposits cover the study area, which includes lagoonal deposits, recent delta deposits, red clays, gravel and sandy materials. |
|
| Shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in river deltas, on floodplains and offshore from beach sands. |
|
| Shallow-water units include a lagoonal peneroplid-miliolid-molluscan facies within a restricted tidal-flat platform and an open-water, shelf-edge, coralgal-orbitoid facies. |
|
| Source rocks for these basins are frequently anoxic shales deposited in restricted lagoonal conditions in Early Tertiary grabens under the back arcs. |
