Jessup is an unincorporated community and census-designated place in Howard County, Maryland and Anne Arundel County, Maryland, United States. The population was 7,137 at the 2010 census.
Guilford is an unincorporated community located in Howard County in the state of Maryland in the United States. The location is named for the Guilford Mill. Guilford is near Kings Contrivance one of the nine "villages" of Columbia.
Quartz monzonite or adamellite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Because of its coloring, it is often confused with granite, but whereas granite contains more than 20% quartz, quartz monzonite is only 5–20% quartz. Rock with less than five percent quartz is classified as monzonite. A rock with more alkali feldspar is a syenite whereas one with more plagioclase is a quartz diorite. The fine grained volcanic rock equivalent of quartz monzonite is quartz latite.
Charnockite is applied to any orthopyroxene-bearing quartz-feldspar rock, formed at high temperature and pressure, commonly found in granulite facies metamorphic regions, as an end-member of the charnockite series.
Soldiers Delight Natural Environmental Area is a nature reserve near Owings Mills in western Baltimore County, Maryland, USA. The site is designated both as a Maryland Wildland and as a Natural Environment Area and is part of the Maryland Wildlands Preservation System. The site's protected status is due to the presence of serpentine soil and over 39 rare, threatened, or endangered plant species along with rare insects, rocks and minerals.
The Franklin Glacier Complex is a deeply eroded volcano in the Waddington Range of southwestern British Columbia, Canada. Located about 65 km (40 mi) northeast of Kingcome, this sketchily known complex resides at Franklin Glacier near Mount Waddington. It is over 2,000 m (6,600 ft) in elevation and because of its considerable overall altitude, a large proportion of the complex is covered by glacial ice.
Granite is an unincorporated community in Baltimore County, Maryland, United States. Originally known as Waltersville, it was renamed Granite in recognition of its principal product. The village was the center of this industry, which during its peak in the late 19th century provided building materials for major projects throughout the eastern seaboard.
In structural geology, a roof pendant, which also known as a pendant, is a mass of country rock that projects downward into and is entirely surrounded by an igneous intrusion such as a batholith or other pluton. In lay terminology sometimes "rock hat" is used. A roof pendant is an erosional remnant that was created by the removal by erosion of the overlying country rock that formed the roof of the igneous intrusion that encloses it. If this downward protruding mass of roof rock still has a connection to the main, surrounding mass of country rock, they are known by structural geologists as either septa or screens. Roof pendants typically have been strongly metamorphosed through the processes of contact metamorphism.
Whiskey Bottom Road is a historic road north of Laurel, Maryland that traverses Anne Arundel and Howard Counties in an area that was first settled by English colonists in the mid-1600s. The road was named in the 1880s in association with one of its residents delivering whiskey after a prohibition vote. With increased residential development after World War II, it was designated a collector road in the 1960s; a community center and park are among the most recent roadside developments.
The Ridgeley sandstone is a sandstone or quartzite of Devonian age found in the Appalachian Mountains of Pennsylvania, Maryland, West Virginia, and Virginia, United States. The Ridgeley is fine-grained, siliceous, calcareous in its lower strata, sometimes fossiliferous, and sometimes locally pebbly or conglomeritic. Varying in thickness from 12 to 500 feet, this rock slowly erodes into white quartz sand that often washes or blows away, but sometimes accumulates at large outcrops. When freshly broken, the rock is white, but outcrop surfaces are often stained yellowish by iron oxides.
Quarry Lake is a manmade lake in Baltimore County, Maryland. It is one of the deepest lakes in the state. The lake is surrounded by mixed residential development and commercial development, including single-family homes, condominiums, shops, and office buildings.
The Ellicott City Granodiorite is a Silurian or Ordovician granitic pluton in Howard and Baltimore Counties, Maryland. It is described as a biotite granodiorite along the margin of the intrusion which grades into a quartz monzonite in its core. It intrudes through the Wissahickon Formation and the Baltimore Gabbro Complex.
The Port Deposit Gneiss is a Paleozoic gneiss formation in Harford County, Maryland. It is described as a "Moderately to strongly deformed intrusive complex, chiefly composed of quartz diorite gneiss. Rock types include gneissic biotite-quartz diorite, hornblende-biotite-quartz diorite, and biotite granodiorite, with minor amounts of quartz monzonite and hornblende-quartz diorite. Moderate protoclastic foliation grades into strong cataclastic shearing." It intrudes into the Volcanic Complex of Cecil County.
The geology of Wisconsin includes Precambrian crystalline basement rock over three billion years old. A widespread marine environment during the Paleozoic flooded the region, depositing sedimentary rocks which cover most of the center and south of the state.
