They form an inverted metamorphic sequence grading eastward into an ∼1-km-wide, amphibolite-facies−derived mylonite zone in the hanging wall. The K‐Ar and Rb‐Sr ages of the schists increase with distance from the fault: from 4 m.y. Aronson, 1968). The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. Strain hardening and strength of clay‐rich fault gouges. The Torlese Group is metamorphosed predominantly in the prehnite-pumpellyite zone, and the Otago Schist in higher grade zones. Within the bends region of the Alpine Fault two structural trends have been identified. This displacement is compatible with distributed lateral and vertical shear within the mylonite zone since inception of significant convergence on the plate boundary in the late Neogene. https://www.sciencelearn.org.nz/resources/330-the-alpine-fault Geophysics, Biological Frictional Metamorphism of Coal in the Upper Silesia Coal Basin, Southern Poland. during Kaikoura Orogenic uplift on the Alpine Fault. Mode of crustal shortening adjacent to the Alpine Fault, New Zealand. It is probable that prograde metamorphism in the root zone of the Southern Alps releases metamorphic fluids that at some region rise vertically rather than following the trace of the Alpine Fault up to the surface, owing to the combined effects of the fault, the disturbed isotherms under the Southern Alps, and the brittle–ductile transition.

FISSION TRACK THERMOCHRONOLOGIC ANALYSIS OF THE RYOKE BELT AND THE MEDIAN TECTONIC LINE, SOUTHWEST JAPAN. Quantifying magnitudes of shear heating in metamorphic systems. This region has generated great interest among geologists, in part because it is one of only a few places where the surface tectonic record As mountains are built along tectonic plates, preexisting rocks affected by temperature or pressure can create entirely new kinds of rocks. Four zones of progressive metamorphism are recognized: the Chlorite, Biotite, Almandine, and Oligoclase zones. impact metamorphism. Geophysics, Marine The D3 trend overprints D2 close to the Alpine Fault and is subparallel to the fault. The type of rock that a metamorphic rock usedto be, prior to metamorphism, is called the protolith. Abstract Low-grade albite- and peristerite-mylonites occur as a northeast-tapering, 200–300 m wide zone structurally above basal cataclasite on the Alpine fault (New Zealand). Do Great Earthquakes Occur on the Alpine Fault in Central South Island, New Zealand?. Mountain formation refers to the geological processes that underlie the formation of mountains.These processes are associated with large-scale movements of the Earth's crust (tectonic plates).Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. 25 Ma (Sutherland and Norris, 1995). X-Y is the Haast River Section of Figure 21-11. From Turner (1981) Metamorphic Petrology: Mineralogical, Field, and Tectonic Aspects. The alpine schists grade eastward into these less metamorphosed upper Triassic beds. The most important agents of metamorphism include temperature, pressure, and fluids. These metamorphic zone boundaries are subparallel to the fault for 350 km along the strike. The central Alpine Fault exposes rocks that have been deformed in the middle crust as recently as recently as 3 … The rupture will produce one of the biggest earthquakes since European settlement of New Zealand, and it will have a major impact on the lives of many people. Ductile structures in the greenschist facies rocks of the Alpine Schist that lie in the headwaters of the Whataroa, Callery, and Balfour valleys formed during Mesozoic deformation, similar to those in the Otago Schist to the south. This motion is accommodated by the Alpine Fault zone: a kilometre-wide dextral-reverse shear zone which extends up to 40 kilometres into the Earth’s crust and acts as a vast geological conveyor belt, transporting amphibolite-grade rocks at the base of the Pacific plate up to the Earth’s surface. Low-grade albite- and peristerite-mylonites occur as a northeast-tapering, 200–300 m wide zone structurally above basal cataclasite on the Alpine fault (New Zealand). Frictional heating during this episode produced the argon depletion. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. The Alpine Fault has a high probability (estimated at 30%) of rupturing in the next 50 years. New Zealand Journal of Geology and Geophysics. By the use of field criteria this zone of decreasing metamorphism has been divided into five metamorphic belts. In the Southern Alps there is a significant uplift following the Cretaceous Rangitata Orogeny, probably in the order of 11–15 km. Tethys–Atlantic interaction along the Iberia–Africa plate boundary: The Betic–Rif orogenic system. McGraw-Hill. Working off-campus? Adopting a friction model for the fault and applying the known geological history of motion of the Alpine fault, we show that the metamorphism resulted from frictional heating during the 360‐km right lateral slip on the Alpine fault during the Mesozoic (Rangitata) period of fault motion (140–80 m.y.

Field relations show that the source of heat that produced the argon depletion aureole was the fault itself. Tasman Belt and the Alpine Fault. Bull and Cooper, 1986; Wellman, 1979). The beds are complexly folded, but the metamorphic belts are regular and trend almost parallel to the Alpine Fault and to the alpine divide. Geophysics, Geomagnetism and Paleomagnetism, History of From the crest of the range westward to the Alpine Fault the grade of metamorphism increases from indurated sedimentary rocks to high-grade schists and gneisses. It is probable that prograde metamorphism in the root zone of the Southern Alps releases metamorphic fluids that at some region rise vertically rather than following the trace of the Alpine Fault up to the surface, owing to the combined effects of the fault, the disturbed isotherms under the Southern Alps, and the brittle–ductile transition. No frictional heat along the San Gabriel fault, California: Evidence from fission-track thermochronology. Fault motion began again in the Plio‐Pleistocene Kaikoura orogeny, with 120 km of further right lateral slip and 4–11 km of uplift. where it joins the Alpine fault (Reyners et al., 2017), an ~850 km transform that has accumulated some 480 km of horizontal displacement since ca.

Shear heating and the state of stress on faults. Geochronological evidence for ∼ 530–550 Ma juxtaposition of two Proterozoic metamorphic terranes in the Musgrave Ranges, Central Australia. The continued growth of the Southern Alps is somewhat unique in that these mountains lie where the Pacific and Australian plates collide and simultaneously slide past one another along a large transform fault called the Alpine Fault. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. We examine processes of graphite emplacement and deformation in the Alpine Fault Zone, New Zealand’s In the Haast Schists, the minerals that make up greywacke became coarser grained and altered to other minerals including quartz, feldspar and biotite. ; Harper and Landis 1967).
