| In the east, which is lower and flatter, river gravels and alluvium from the North Sea have produced dark, rich soils. |
|
| Among the gravels there were shiny crystals of the mineral gypsum, the residue left behind when seawater evaporates. |
|
| Cornbrash is a variety of limestone underlying the local gravels already extracted. |
|
| Most recently, the alluvial gem gravels of the Songea and Tunduru regions in the south have been productive. |
|
| The Axamilpa river drains this area and along its banks a sequence of Late Cenozoic sands, silts, and gravels are exposed. |
|
| Large quantities of glacier meltwater deposited various kinds of material, the most important of which is called outwash, consisting mostly of sands and gravels. |
|
| The topographic expression of these gravels suggests they represent uplifted and dissected alluvial fans that accumulated along the foot of the Western Ranges. |
|
| Continued erosion by fast-flowing water eroded the uplands to the north of the Gippsland Basin and covered the coal measures with sands and gravels. |
|
| In glacial terrains coarse-grained, so-called Gilbert-type deltas of gravels and sands are common, and these pass in deeper water into varved sediments. |
|
| The carbonate products are made up of oolitic grains, oolitic gravels, benthic foraminifers and crinoid ossicles, in decreasing order of abundance. |
|
| It is not necessarily contemporary with the gravels in which it is found. |
|
| Lothagam is a more restricted area and its strata are older-late Miocene to early Pliocene, overlain unconformably by Quaternary sands, gravels, and coquinas. |
|
| We always get lumped into the same category, which really gravels me. |
|
| This story, like a lot of other ones about us, really gravels me. |
|
| The inner parts of this channel were filled by glacially derived sands and gravels long ago, and infilling by mud and silt has continued since. |
|
| A program of pitting for diamondiferous gravels was completed in the Upper Chicoria Creek area. |
|
| The Southern Lowlands consist of Miocene and Pliocene sands, clays, and gravels. |
|
| The mudstones are not exposed by the bed of the river, as there is a layer of gravels and then alluvium above the bedrock. |
|
| Medium-grade gravels tend to be easier to walk on than smaller grades, rounded pea shingle or large cobbles. |
|
| In Flanders, sands, gravels and marls predominate, covered by silts in places. |
|
|
|
| The BAJV commenced operations in April 2011 and aims to develop an alumina refinery to produce alumina from locally mined bauxitic gravels. |
|
| As well as an abundant supply of game and edible plants, the river gravels were rich in flint deposits, which early humans would have found an invaluable resource. |
|
| Miners discovered old underground beach and river gravels rich with gold. |
|
| In mountainous torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the destruction of larger rocks. |
|
| In the Touajil region, the company has found in the past three months many more diamonds and more angular pyropes during the sampling program of the gravels and surface sands. |
|
| Smaller fragments are used for gravels or for ornamental pathways. |
|
| Since these fine gravels can become muddy when they get wet, many landscape contractors add a soil stabilizer to bind the fragments so they resist water damage. |
|
| Frequently, gravels are named after the regions where they were quarried. |
|
| It seems to be a characteristic arenophile. Not common in Holderness except on the morainic gravels, being the chief plant on Coneygarth Hill, near Brandesburton. |
|
| Inland behind the Chalk were less resistant sands, clays and gravels. |
|
| It is predominantly of a brown forest soil type with some gleying, the lower parts being formed from raised beach sands and gravels derived from Old Red Sandstone and lavas. |
