Gimlet Rock
Carreg yr Imbill is the remains of a large dolerite with pegmatite pods and quarry at Pwllheli, Gwynedd, Wales. The dolerite was mined by the Liverpool and Pwllheli Granite Company (sometimes known as the Pwllheli Granite Company), which used the diorite for stone setts to pave the streets. The worked out quarry forms the basis for a large holiday village which is run by the Haulfryn Group, the same company which runs The Warren The Warren, originally known as Warren House, is a Grade II listed building located in the parish of West Wickham and the postal district of Hayes, Greater London, England.

Carreg Yr Imbill - Gimlet Rock Pwllheli
Aberdaron is a community (Wales), community, electoral ward and former fishing village at the western tip of the Llŷn Peninsula in the Wales, Welsh county of Gwynedd. It lies west of Pwllheli and south west of Caernarfon, and has a population of 965. The community includes Bardsey Island ( cy, Ynys Enlli), the coastal area around Porthor, and the villages of Anelog, Llanfaelrhys, Penycaerau, Rhoshirwaun, Rhydlios, Uwchmynydd and Y Rhiw. It covers an area of just under 50 square kilometres. Y Rhiw and Llanfaelrhys have long been linked by sharing rectors and by their close proximity, but were originally ecclesiastical parishes in themselves. The parish of Bodferin/Bodverin was assimilated in the 19th century. The village was the last rest stop for pilgrims heading to Bardsey Island (Ynys Enlli), the legendary "island of 20,000 saints". In the 18th and 19th centuries it developed as a shipbuilding centre and port. The mining and quarrying industries became major employers, and ...

Granite Setts
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly always m ...

Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''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. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ...

Sett (paving)
A sett, also known as a block or Belgian block, is a broadly rectangular quarried stone used in paving roads and walkways. Formerly in widespread use, particularly on steeper streets because setts provided horses' hooves with better grip than a smooth surface, they are now encountered rather as decorative stone paving in landscape architecture. Setts are often referred to as "cobblestones", although a sett is distinct from a cobblestone in that it is quarried or worked to a regular shape, whereas the latter is generally a small, naturally-rounded rock. Setts are usually made of granite. Places Europe Places paved with setts include many streets in Rome and elsewhere in Italy (where blocks are called ''sampietrini'' or ''bolognini''), since the technique was first used by Romans. In Aberdeen (Scotland), and much of Edinburgh's Old Town and New Town, a large number of streets retain the original setts. Silloth on Solway, a seaside town in Cumbria, still has setts (originally ...
