Chiloé Block, the Glossary

Index Chiloé Block

The Chiloé Block or Chiloé Terrane is a geotectonic unit making up the basement of large parts of south-central Chile between 41° and 45°S.[1]

Basement (geology)

In geology, basement and crystalline basement are crystalline rocks lying above the mantle and beneath all other rocks and sediments.

See Chiloé Block and Basement (geology)

Chile

Chile, officially the Republic of Chile, is a country in western South America.

See Chiloé Block and Chile

Continental fragment

Continental crustal fragments, partly synonymous with microcontinents, are pieces of continents that have broken off from main continental masses to form distinct islands that are often several hundred kilometers from their place of origin.

See Chiloé Block and Continental fragment

Liquiñe-Ofqui Fault

The Liquiñe-Ofqui Fault is major geological fault that runs a length of roughly in a NNE-SSW orientation and exhibits current seismicity. Chiloé Block and Liquiñe-Ofqui Fault are Chile geography stubs.

Proterozoic

The Proterozoic is the third of the four geologic eons of Earth's history, spanning the time interval from 2500 to 538.8Mya, the longest eon of the Earth's geologic time scale.

See Chiloé Block and Proterozoic

South American Plate

The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge. Chiloé Block and south American Plate are geology of Argentina and geology of Chile.

Suture (geology)

In structural geology, a suture is a joining along a major fault zone, of separate terranes, tectonic units that have different plate tectonic, metamorphic and paleogeographic histories.

See Chiloé Block and Suture (geology)

Tectonics

Tectonics are the processes that result in the structure and properties of the Earth's crust and its evolution through time.

See Chiloé Block and Tectonics

Terrane

In geology, a terrane (in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or "sutured" to crust lying on another plate. Chiloé Block and terrane are terranes.
