The geology of the Grand Teton area consists of some of the oldest rocks and one of the youngest mountain ranges in North America. The Teton Range, partly located in Grand Teton National Park, started to grow some 9 million years ago. An older feature, Jackson Hole. In SW Amazon Craton, along the boundary between the Ventuari-Tapajós ( to Ga) and the Rio Negro-Juruena ( to Ga) provinces, an association of volcanic .
Point Reyes National Seashore is an ideal destination for field trips to examine the geology and natural history of the San Andreas Fault Zone and the North Coast of California. The San Andreas Fault Zone crosses the Point Reyes Peninsula between Bolinas Lagoon in the south and Tomales Bay in the north. The map below shows 13 selected fieldFile Size: 1MB. Dark-gray to grayish-black, rusty-weathering sulfidic slate and phyllite interlayered with felsic volcanic rocks and tuffs, and amphibolite (Opa). Stratified rocks of the Bronson Hill arch and Sawyer Mountain belt.

The southern part of the Abitibi Belt in Quebec is dominated by a prominent deformation corridor, the Cadillac-Larder Lake Fault Zone. This zone is oriented E-W and separates a volcanic domain in the north from an essentially sedimentary domain in the south.

Bornhorst, Rodney C. Johnson, Rodney C. Johnson, P. Sims, L.M.H. Carter. The greenstones are locally in tectonic contact with compositionally layered grey gneisses as old as ~ Ga and, in the southern part, are intruded by the ~ Ga Anhalt granitoid suite, providing a minimum age for the greenstones.
The oldest felsic volcanic rocks so far identified are Ga in by: 2. The Sonoma Volcanics are part of a succession of volcanic fields aligned along the East Bay fault system (McLaughlin et al., ; Graymer et al., b), which splays inboard of the San Andreas Fault south of San Francisco Bay ().Earlier workers recognized that the volcanism generally becomes younger to the northwest (Fox et al., a; Dickinson, ).Cited by: 9.
The Southern Indian Domain flanks the Lynn Lake–Rusty Lake belt to the north and, for the most part, correlates with the Rottenstone Domain in Saskatchewan. It is dominated by foliated granitoid orthogneiss and clastic sedimentary rocks that include conglomerate, greywacke and metaturbidite, as well as subordinate rocks of volcanic origin.
Recent. Geology of volcanic rocks in the south half of the Ishpeming greenstone belt, Michigan Bulletin P By: Theodore J. Bornhorst, Rodney C. Johnson, and L.M.H. Carter. The Southern Indian Domain flanks the Lynn Lake–Rusty Lake belt to the north and, for the most part, correlates with the Rottenstone Domain in Saskatchewan.
It is dominated by foliated granitoid orthogneiss and clastic sedimentary rocks, including conglomerate, greywacke and metaturbidite, and subordinate amounts of volcanic rocks.
Bedrock geology of the Gemmell Lake area, Lynn Lake greenstone belt, northwestern Manitoba (parts of NTS 64C11, 14); Manitoba Geological Survey, Preliminary Map PMAP. The Andean Volcanic Belt runs through the southwestern part of South America.
It is split up into four volcanic zones. The zone in Patagonia is known as the Austral Volcanic Zone or AVZ. The AVZ arcs from south of the Patagonian Volcanic Gap to the Tierra del Fuego archipelago, totaling a distance well over miles (1,km). Lynn Lake Belt. The Paleoproterozoic Lynn Lake and Rusty Lake greenstone belts occur in the interior (Reindeer) zone of the Trans-Hudson Orogen, that is, in the zone formed as new ocean floor, or in oceanic to continental volcanic arcs and related marine and continental sedimentary basins.
Metavolcanic rocks in the Lynn Lake – Rusty Lake. The mountains and fjords of Greenland preserve a record of nearly four billion years of Earth history - a story of mountain building, volcanic eruptions, primitive life and ice ages.
During the vast period of time, through processes of continental drift, Greenland has journeyed from the southern hemisphere through the tropics to its present polar position.
No deep water lacustrine conditions are known. Extension continued into the Pliocene, particularly in the Turkana Basin and the northern part of the Kerio Basin. Finally, the old half grabens were abandoned and a belt of minor fault swarms and volcanic centers was established east of Lake Turkana and in the southern part the lake.
The Bird River greenstone belt consists partially of supracrustal rocks, including bimodal metavolcanic sequences and platform-type metasedimentary sequences (Trueman, ).
Part of the belt is intruded by the Bird River Sill, a thin, fault-disrupted, differentiated maﬁc-ultramaﬁc intrusion with signiﬁcant Ni-Cu, Cr and PGE mineralization.
The Coastal Plain is the largest geologic element in the state, covering about 45 percent of the land area. The most common sediment types are sand and clay, although a significant amount of limestone occurs in the southern part of the Coastal Plain.
In the Coastal Plain, geology is best understood from studying data gathered from well drilling. The Birimian terranes in the southern part of the West African craton are a mix of metamorphosed volcanic, sedimentary, and plutonic rocks and low-grade metavolcanics and metasediments.
Almost half of the terranes consist of alkaline granites. The rocks formed over a period of about 50 million years between Ga and Ga years ago. The geology of England's Lake District is dominated by sedimentary and volcanic rocks of mainly Ordovician age underpinned by large granitic intrusions.
Younger sedimentary sequences outcrop on the edges of the Lake District area, with Silurian to the south, Carboniferous to the north, east and west and Permo- Triassic to the west and east.
Eruptive centers for both basaltic and rhyolitic volcanic rocks are concentrated in the zone of faults and in some nearby subsidiary fault zones. A belt of late Cenozoic basaltic flows, extending from the Bend area nearly to the Idaho border (Walker, ), obscures much of the older Cenozoic geology along the Brothers fault zone.
