Sandwich Fault Zone
The Sandwich Fault Zone is a fault zone that runs northwest from Oswego to Ogle County, transecting Lee County in Northern Illinois. The fault has generally not been active, although there was a minor earthquake in 2002, and another, slightly larger one, in 2010. It has a largely 400 to 600-foot vertical displacement, although parts can reach up to an 800-foot displacement, and is likely a configuration of several smaller faults, varying in both direction and displacement.

Fault Zone
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Oswego, Illinois
Oswego is a village in Kendall and Will Counties, Illinois, United States. Per the 2020 census, the population was 34,485. Oswego is the largest municipality in Kendall County. It is a suburb of Chicago, Illinois. History In 1833, William Smith Wilson, his wife Rebecca, and his brother-in-law Daniel Pearce moved to the area now known as Oswego. The land belonged to the local Potawatomi, Ottawa, and Chippewa tribes, but the United States government removed the Native Americans when the government started surveying the land along the Fox River in Kendall County. In 1842, the federal government placed the land for sale at an established price of $1.25 an acre. After the sale of the land, Lewis Brinsmaid Judson and Levi F. Arnold from New York laid out the village and named it "Hudson". However, when a post office was established, its location was given as "Lodi". Confusion over the official name of the area led to a decision in January 1837, when the citizens gathered and vot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ogle County, Illinois
Ogle County is a county in the northern part of the U.S. state of Illinois. According to the 2010 United States Census, it had a population of 53,497. Its county seat is Oregon, and its largest city is Rochelle. Ogle County comprises Rochelle, IL Micropolitan Statistical Area, which is also included in the Rockford- Freeport-Rochelle, IL Combined Statistical Area. History Ogle County was formed in 1836 out of Jo Daviess and LaSalle counties, and named in honor of Captain Joseph Ogle, a veteran of the Revolutionary War who settled in Illinois in 1785. Ogle County government was organized in 1837; before that time it remained assigned to Jo Daviess County for legislative, taxation, and judicial matters. In 1839, part of Ogle County was partitioned off to form Lee County. Ogle County was a New England settlement. The founders of Oregon and Rochelle arrived from New England; they were "Yankees", descendants of English Puritans who had settled New England in the 1600s. They ...

Lee County, Illinois
Lee County is a county located in the U.S. state of Illinois. According to the 2010 census, it has a population of 36,031. Its county seat is Dixon. The Dixon, IL Micropolitan Statistical Area includes all of Lee County. History The area's first non-native settlers were mostly from the six New England states. The early nineteenth century saw a wave of westward movement from New England, due largely to completion of the Erie Canal and the end of the Black Hawk War. The area that included present-day Lee County was delineated as St. Clair County in 1809. In 1823, a large section of northern St. Clair County was partitioned off as Fulton County. In 1825, the northwestern portion of that county was partitioned off as Putnam County. In 1831, the area was further partitioned into Jo Daviess County. A section of that county was partitioned off in 1836 as Ogle County, and in 1839 the bottom half of Ogle County was split off as Lee County. It is largely understood that the county's ...

Northern Illinois
Northern Illinois is a region generally covering the northern third of the U.S. state of Illinois. The region is by far the most populous of Illinois with nearly 9.7 million residents as of 2010. Economics Northern Illinois is dominated by the metropolitan areas of Chicago, the Quad Cities, and Rockford, which contain a majority (over 75%) of Illinois' population and economic activity, including numerous Fortune 500 companies and a heavy manufacturing, commercial, retail, service, and office based economy. Much of the economic activity of the region is centered in the Chicago Loop, the Illinois Technology and Research Corridor, and the Golden Corridor. However, rural sections of this region are highly productive agriculturally, and are part of the Corn Belt. The headquarters for John Deere farming equipment are located in Moline. Additional smaller cities in this area include Kankakee, LaSalle-Peru, Ottawa, Freeport, Dixon, and Sterling- Rock Falls, which still have ...

Geology Of Illinois
The geology of Illinois includes extensive deposits of marine sedimentary rocks from the Palaeozoic, as well as relatively minor contributions from the Mesozoic and Cenozoic. Ice age glaciation left a wealth of glacial topographic features throughout the state. Precambrian Geology Precambrian rocks of Illinois are deeply buried by 2000–13000 feet (610–3960 m) of later sediments. Drilling has revealed these rocks to be primarily intrusive felsic igneous rocks, though some extrusive felsic rocks have also been recovered from boreholes. Precambrian rocks of Illinois are highly faulted; tectonic extension and related thermal subsidence have led to the formation of two major sedimentary basins. These basins, termed the Illinois Basin and Michigan Basin, allowed for extensive deposition of sedimentary rock during the Palaeozoic Era. The Illinois Basin is a northwest-southeast asymmetrical structural basin that is filled with more than 4000 meters of Paleozoic sedimentary rocks. Th ...

Geography Of DeKalb County, Illinois
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
