Question: What is the official French name of the annular lakes on the large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (the North American Craton or Laurentia)?
Context: A shield is generally a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas.  In all cases, the age of these rocks is greater than 570 million years and sometimes dates back 2 to 3.5 billion years.  They have been little affected by tectonic events following the end of the Precambrian, and are relatively flat regions where mountain building, faulting, and other tectonic processes are greatly diminished compared with the activity that occurs at the margins of the shields and the boundaries between tectonic plates. Laurentia or the North American Craton is a large continental craton that forms the ancient geological core of the North American continent.  Many times in its past, Laurentia has been a separate continent, as it is now in the form of North America, although originally it also included the cratonic areas of Greenland and also the northwestern part of Scotland, known as the Hebridean Terrane.  During other times in its past, Laurentia has been part of larger continents and supercontinents and itself consists of many smaller terranes assembled on a network of Early Proterozoic orogenic belts.  Small microcontinents and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable Precambrian craton seen today. The Canadian Shield, also called the Laurentian Plateau, or "Bouclier canadien " (French), is a large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (the North American Craton or Laurentia).  Composed of igneous rock resulting from its long volcanic history, the area is covered by a thin layer of soil.  With a deep, common, joined bedrock region in eastern and central Canada, it stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada; it also extends south into the northern reaches of the United States.  Human population is sparse, and industrial development is minimal, while mining is prevalent. The Lac à l'Eau Claire (the official name, in French), also called the Clearwater Lakes in English, is a calque of Wiyâšâkamî in Northern East Cree (changed form of "wâšâkamî" or "wâšekamî" in more southerly Cree dialects) and Allait Qasigialingat by the Inuit, are a pair of annular lakes on the Canadian Shield in Quebec, Canada, near Hudson Bay. The Vishnu Basement Rocks is the name recommended for all Early Proterozoic crystalline rocks (metamorphic and igneous) exposed in the Grand Canyon region.  They form the crystalline basement rocks that underlie the Bass Limestone of the Unkar Group of the Grand Canyon Supergroup and the Tapeats Sandstone of the Tonto Group.  These basement rocks have also been called either the Vishnu Complex or Vishnu Metamorphic Complex.  These Early Proterozoic crystalline rocks consist of metamorphic rocks that are collectively known as the "Granite Gorge Metamorphic Suite"; sections of the Vishnu Basement Rocks contain Early Paleoproterozoic granite, granitic pegmatite, aplite, and granodiorite that have intruded these metamorphic rocks, and also, intrusive Early Paleoproterozoic ultramafic rocks. The Puerto Edén Igneous and Metamorphic Complex is a large coherent but varied group of metamorphic and igneous rocks –in other words a geologic complex– that crops out in the Patagonian channels of Magallanes Region.  At present the rocks of the complex include migmatites, plutonic rocks and high-grade metamorphic rocks.  To the west the Puerto Edén Igneous and Metamorphic Complex bounds the South Patagonian Batholith. The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2000 km long geological rift in the center of the North American continent and south-central part of the North American plate.  It formed when the continent's core, the North American craton, began to split apart during the Mesoproterozoic era of the Precambrian, about 1.1 billion years ago.  The rift failed, leaving behind thick layers of rock that are exposed in its northern reaches, but buried beneath later sedimentary formations along most of its western and eastern arms.  Those arms meet at Lake Superior, which is contained within the rift valley.  The lake's north shore in Ontario and Minnesota defines the northern arc of the rift.  From the lake, the rift's eastern arm trends south to central lower Michigan.  The western arm runs from Lake Superior southwest through portions of Wisconsin, Minnesota, Iowa, and Nebraska to northeastern Kansas. The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock.  The first rocks were laid down in Precambrian times, when the area around Yosemite National Park was on the edge of a very young North American continent.  The sediment that formed the area first settled in the waters of a shallow sea, and compressive forces from a subduction zone in the mid-Paleozoic fused the seabed rocks and sediments, appending them to the continent.  Heat generated from the subduction created island arcs of volcanoes (not unlike Japan) that were also thrust into the area of the park.  In time, the igneous and sedimentary rocks of the area were later heavily metamorphosed. The Trans-Hudson orogeny or Trans-Hudsonian orogeny was the major mountain building event (orogeny) that formed the Precambrian Canadian Shield, the North American Craton (also called Laurentia), and the forging of the initial North American continent.  It gave rise to the Trans-Hudson orogen (THO), or Trans-Hudson Orogen Transect (THOT), (also referred to as the Trans-Hudsonian Suture Zone (THSZ) or Trans-Hudson suture) which is the largest Paleoproterozoic orogenic belt in the world.  It consists of a network of belts that were formed by Proterozoic crustal accretion and the collision of pre-existing Archean continents.  The event occurred 2.0-1.8 billion years ago. The Limpopo Belt is located in South Africa and Zimbabwe, runs E-NE, and joins the Kaapvaal craton to the south with the Zimbabwe craton to the north.  The belt is of high-grade metamorphic rocks that have undergone a long cycle of metamorphism and deformation that ended 2.0 billion years ago, after the stabilisation of the adjacent massifs.  The belt comprises 3 components: the Central Zone, the North Marginal Zone and the South Marginal Zone.
