Types of Plate Boundaries Camryn Tomlinson. The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. More often, an array of strike-slip and dip-slip faults will operate together. The red line on this map shows our plate boundary (see Module 2). Image courtesy of the U.S. Geological Survey. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. 1A) there are opportunities to derive long earthquake records from sediments that, although not offset by fault rupture, are uniquely tied to Alpine fault earthquakes. In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed. The average slip rates in the fault's central region are abo… Two tectonic plates (Oceanic and Continental) collide from compression stress and form a convergent plate boundary. St. Andreas Transform Fault Alpine Fault New Zealand The types of transform fault that are always the longest Oceanic Transform Fault Continental Transform Fault. In between, through most of the South Island, the two plates grind past each other along the Alpine Fault. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. Event 3- Seafloor Spreading Location Six Alpine Fault Transform Boundary 5 Event 1- Volcanoes 20 Event 2- Island Spreading Conclusion: Your conclusion will include a summary of the lab results and an interpretation of the results. A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these boundaries. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. The Alpine Fault is called a strike slip or transform fault. Movement along this fault has uplifted the Southern Alps and helped shape the South Island landscape we know today. U.S. Department of Commerce, The Northeast Caribbean – Plate Tectonics in Action, Océano Profundo 2018: Exploring Deep-sea Habitats off Puerto Rico and the U.S. Virgin Islands, National Oceanic and Atmospheric Administration. The impact of the two colliding plates buckles the edge of one or both plates into a rugged mountain range; sometimes can bend other plate down into a deep seafloor trench. Disclaimer Have any problems using the site? Transform boundaries are also found on larger scales on land like the Alpine fault in New Zealand and the San Andreas fault in Western North America pictured below. The formation of Southern Alps is attributed to the tectonic activity, including earthquakes along this transform boundary. STUDENT ACTIVITY: New Zealand plate boundary models Activity idea In this activity, students make and/or observe two 3D moving models of the different tectonic plate boundaries under the North and South Islands representing the North Island subduction zone and the South Island Alpine Fault. EXPLORING THE PLANETS 3 The crust type and general of thickness of the crust. When two plates come together, it is known as a convergent boundary. When a tectonic boundary is oriented oblique relative to plate motion, a combination of strike-slip and dip-slip faulting will occur. National Oceanic and Atmospheric Administration Sometimes, a single oblique-slip fault will carry most of the deformation; an example of this is the Alpine Fault in New Zealand. The last such earthquake took place in … Download image (jpg, 76 KB). For more information, see the following related content on ScienceDaily: Content on this website is for information only. Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench.

The transform fault is simply a strike-slip fault as the plates move, the crust is fractured and broken. Site of the Next Major Earthquake on the San Andreas Fault? This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges.. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. At a transform boundary, two tectonic plates slide past each other. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. Transform plate boundaries occur where two lithospheric plate slide past each other horizontally along a single or a group of deep nearly vertical steep fault planes. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. By the end of this activity, students should be able to: The mountains are rising at 7 millimetres a year, but erosion wears them down at a similar rate. It’s the "on-land" boundary of the Pacific and Australian Plates. Contributor: Hobart King Publisher, Geology.com The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time. Convergent Plate Boundary (Ocean-to-Continent). Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. It is not intended to provide medical or other professional advice.

The type of plate boundary at the Alpine Fault is a transform boundary. Privacy Policy It forms the sharp line separating the snow-covered Southern Alps in the east from the low coastal plain bordering the Tasman Sea in the west. It runs as a single structure for over 500 km. This lateral motion of one plate against another can show faults in the surface crust (As the Alpine Fault shows through the Southern Alps) The sliding motion also causes lots of earthquakes along the fault … Transform Plate Boundaries are locations where two plates slide past one another. A transform fault or boundary is where the tectonic motion is primarily horizontal meaning they slide past each other. •Chapter 7- Plate Tectonics, Ch.8 Earthquakes, Ch.9 Volcanoes pg.

The Alpine Fault, marked here by the yellow line, stretches nearly the entire length of Te Waipounamu, the South Island of Aotearoa New Zealand. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otagomoving South. 6. Questions? The mountain belts listed above in bold face are at ocean-continents Convergent Plate Boundaries (North American Cordillera, Andes) or continent-continent Convergent Plate Boundary (the Himalayas are the best example of this type of plate boundary). Answer to: Is the Alpine Fault convergent, divergent, or transform? Earthquakes are common along these faults. The biggest faults mark the boundary between two plates. The Philippine Fault Zone (PFZ) extends 1200 km across the Philippine archipelago behind the convergent boundary of the Philippine Trench and the subduction of the Philippine Sea Plate. The Alpine Fault cuts through New Zealand. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. A chain of volcanoes often forms parallel to the boundary, to the mountain range, and to the trench. This image shows the three main types of plate boundaries: divergent, convergent, and transform.
