La Herradura Formation
La Herradura Formation ( es, Formación La Herradura) is a sedimentary formation of Lower Cretaceous age exposed near La Herradura, Lima, the beach of the same name in Lima, Peru. The sediments of the formation reflect a marine near-shore depositional environment.

Fault (geology)
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 bl ...

Morro Solar
Morro Solar (''morro'' in Spanish language, Spanish means: a rounded promontory) is a headland, situated in the district of Chorrillos District, Chorrillos, to the south of Lima, Peru. Morro Solar is notable for being a site of the Battle of San Juan and Chorrillos between Peruvian and Chilean forces in 1881. Notable landmarks include an astronomical observatory and a monument to an unknown soldier. Its geological formations are rich in silver which is being extracted by several mining companies. Geography Morro Solar, a cluster of hills, is roughly in elevation. It lies near Chorrillos, Peru, Chorrillos, a southern suburb of Lima Province, Lima, occupying an area of . Alexander George Findlay described it as "a remarkable cluster of hills, standing on a sandy plain; when seen from the southward it has the appearance of an island in the shape of a quoin, sloping to the westward, and falling very abruptly in-shore; on its sea face, however, it terminates in a steep cliff, with a s ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hauterivian
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.9 ± 2 Ma and 129.4 ± 1.5 Ma (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian.See Gradstein ''et al.'' (2004) for a detailed geologic timescale Stratigraphic definitions The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus '' Acanthodiscus'' first appears. A reference profile for the base (a GSSP) was officially ratified by the International Union of Geological Sciences in December of 2019, and is placed in La Charce, France. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species ''Spitidis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lima Province
Lima Province is located in the central coast of Peru and is the only province in the country not belonging to any of the twenty-five regions. Its capital is Lima, which is also the nation's capital. Despite its small area, this province is the major industrial and economic powerhouse of the Peruvian economy. It concentrates almost one-third of the country's population and 50% of Peru's GDP in 2012. History The province was created in 1821 as Peru's territory was divided into departments, provinces, districts and parishes. The province was part of the Lima Department, which was formed by the territories of present-day Lima, Callao and Ica regions, and the provinces of Casma, Huarmey and Santa, which later would be part of the ''La Costa Department''. The department was further subdivided as time passed but the Lima Province kept being part of it. Due to the massive migration from other areas of the country, the need to separate the province from the rest of the department ...

Morro Solar Group
The Morro Solar Group ( es, Grupo Morro Solar) is a stratigraphic group of Mesozoic-aged sedimentary formations exposed near Lima, Peru. The groups formations more specifically of Berriasian and Valanginian age (Early Cretaceous) and overlies the Jurassic Puente Piedra Group and underlies the Cretaceous Pamplona Formation. The Morro Solar Group is intruded by sills of andesitic composition.

La Herradura, Lima
La Herradura is a beach located in the Chorrillos District of Lima, Peru. It has been used as a balneario since the beginning of the 20th century and for surfing since the 1960s. Until the 1980s it was one of the most popular beaches in Lima, visited especially by the city's wealthy families. The construction of the road to La Chira beach changed the configuration of the beach and the shore, which was previously sandy, was filled with stones. Since December 28, 2016, La Herradura has been part of the National Reef Registry (RENARO), a registry of protected waves in the country covered by the law on the preservation of reefs appropriate for sports (law no. 27280). Overview La Herradura is located in a place that receives a greater number of hours of sunshine per year compared to the rest of the balnearios in Lima. At the beginning of the 20th century it had a sandy shore, which differentiated it from other spas on the nascent Costa Verde with stones or boulders. Since the c ...
