Exempel på hur man kan använda DOLERITE i en mening

• The backbone of rock in the park is dolerite, while the southern areas at lower altitudes are constituted from sedimentary rocks formed from sediments deposited by marine, glacial and freshwater sources between 355 and 180 million years ago.
• The prominent cliffs with dolerite columns at Cape Raoul were damaged by gunnery practice by warships of the Royal Navy's Australia Station in the late 1800s.
• The area is dominated by granite outcrops along with smaller dolerite areas, the tops of hills are capped with laterite.
• The limestone country rock is intruded by a handful of NE-SW aligned lamprophyre dykes of Silurian to early Devonian age associated with the Strontian Granite Complex and by large numbers of NW-SE aligned dykes of dolerite and basalt of Palaeogene age along with a rather fewer number assigned to the ‘Loch Scridain Suite.
• Cradle Mountain is formed by an igneous dolerite sill that intruded the Permian-Jurassic sedimentary layers, cooling to form a broad hard layer.
• The lava flows are cut through by a swarm of Palaeocene age basalt and dolerite dykes generally aligned NNW-SSE.
• The series which is up to 1000 metres (3000') thick also includes trachyte, dolerite and skomerite which is an altered andesite.
• It is possible to see a particular area known as Hutton's Section in the Salisbury Crags where the magma forced its way through the sedimentary rocks above it to form the dolerite sills that can be seen in the Section.
• A dolerite dyke of Ordovician age intrudes the melange at Trwyn y Gorlech in the north whilst an olivine dolerite dyke of Tertiary age is seen at Cafn Enlli in the southeast.
• The hills are formed largely from the Ordovician age marine mudstones and siltstones of the Penmaen Dewi Shales and Aber Mawr Shale formations which have been intruded by microgabbro (otherwise known as dolerite or diabase) of Ordovician age.
• It consists of two sections fitted together with a mortice and tenon joint, both cut from the local dolerite stone.
• Although they appear to be of abiogenic origin, only that near the dolerite sills points to a probable mantle origin.
• Layered gabbro and dolerite of Silurian age occur at Kapp Laura in easternmost Nordaustlandet, on the island of Storøya, and in the eastern part of the island of Kvitøya.
• Preseli Bluestone dolerite axe heads have been found around the Preseli Hills as well, indicating that there was a population who knew how to work with the stones, In 2015, researchers claimed that some of the stones at Stonehenge came from Neolithic quarries at Carn Goedog and Craig Rhos-y-felin in the Preseli Hills.
• On the eastern side it rises into low, unglaciated dolerite hills and mountains, largely covered with dry sclerophyllous forests, but on the west lies the high doleritic Lake Country, which was extensively glaciated during Quaternary glacial periods and is covered with large numbers of lakes consequently carved into the very hard and erosion-resistant rock.
• In 1903, du Toit was appointed as a geologist within the Geological Commission of the Cape of Good Hope, and he began to develop an extensive knowledge of the geology of southern Africa by mapping large portions of the Karoo and its dolerite intrusions, publishing numerous papers on the subject.
• The hamlet, quarry and Staple Tors to the north are on the granite, while Cox Tor immediately to the west is on the metamorphic aureole, with altered Carboniferous sedimentary rocks of the Culm Measures lower down and calc-silicate hornfels and intrusive dolerite at the summit.
• Diabase is the preferred name in North America, while dolerite is the preferred name in the rest of the English-speaking world, where sometimes the name diabase refers to altered dolerites and basalts.
• The high tabular mountains of the horst, are regular and even in outline, presenting broad domes with precipitous fronts to the north showing the granite structure capped by a series of horizontally bedded sandstone with intruded dolerite sills.
• Unlike the big “outlet” glaciers such as the Beardmore, Shackleton and Liv, the Axel Heiberg is in effect an alpine glacier, cut off from the polar plateau by a dolerite rim and fed entirely from the uncharacteristically heavy snow falling within its own catchment.
