Midcontinent rift map
Detailed Description. Meet the Mid-Continent Rift, one of the most geologically fascinating regions in the United States and Canada.Figure 1a) Bouguer Gravity map of the Midcontinent Rift (Stein et al., 2014). The location of the Grenville orogeny, credited with ending the period of rifting forming the MCRS, is indicated on the map. The star indicates the location of this study’s field site (shown in more detail in Figure 2). The

Rodinia, in geologic time, a supercontinent that incorporated almost all the landmasses on Earth for about 450 million years during the Proterozoic Eon (2.5 billion to 541 million years ago). Rodinia, which was made up of an amalgamation of several connected landmasses and other large cratons lying in close proximity, formed about 1.2 billion years ago, at the …The Midcontinent Rift System is a 1.1 Ga failed continental rift in the Midwestern United States and Canada (Fig. 1).This area contains ~ 1 – 2 × 10 6 km 3 of mafic igneous rocks (Hutchinson et al. 1990; Merino et al. 2013).Rift-related volcanism includes voluminous tholeiitic flood basalt flows, minor picritic flows, and some …For those who work in real estate, the term “plat map” is one with which you already have familiarity.
