This themed issue of Geosphere, "Making the Southern Margin of Laurentia," looks at how the margins of part of our continent were shaped. A couple of questions come immediately to mind: What is Laurentia, and how is it different than the North American continent? Where is its southern margin?
This special issue is launched as Earthscope's Magnetotelluric Transportable Array of seismometers moves slowly across the region, which is providing an unparalleled look into the lithospheric and mantle structure of the region. This themed issue draws attention to this region, in the expectation that the next few years will provide useful new information about the lithospheric and upper mantle structure of the U.S. part of Laurentia.
