This resource is available as a downloadable file, ESRI Service, and as a Web Feature service. Resource includes a Bedrock map, Cross Section, Cross Section, Fault block map, and a text on the Bedrock geology of Isle La Motte and South Hero Island, Vermont. Abstract: Detailed study of the two islands reveals many similarities in structure, stratigraphy and paleontology. Both areas have been cut into fault blocks by "normal" and "thrust" faulting. Isle La Motte has been cut into two blocks, while South Hero Island has been cut into several. The amount and direction of dip of the larger faults is indeterminate, but most are considered normal in accordance with the faults of the Champlain Valley as a whole. Evidence is presented to establish the presence of hitherto unrecognized thrust faulting in the limestone. South Hero Island displays a western belt of simple folding separated by a thrust fault from an eastern belt of more complex folding, the origin of which is attributed to northwesterly moving thrusting forces. The same structural setup is noted in the overlying shaly beds, but faulting is generally indeterminate in the shale.

The EM-60 system, a large-moment frequency-domain electromagnetic loop prospecting system, was operated in the Soda Lakes geothermal area, Nevada. Thirteen stations were occupied at distances ranging from 0.5-3.0 km from two transmitter sites. These yielded four sounding curves--the normalized amplitudes and phases of the vertical and radial magnetic fields as a function of frequency at each station.

This resource is available as a downloadable file, ESRI Service, and as a Web Feature service. Resource includes a Bedrock map, Tectonic map, and a text on the Bedrock geology of the Plainfield Quadrangle, Vermont. For more information see links provided. Abstract: Ordovician, Silurian and probable Devonian sedimentary rocks have been deformed metamorphosed and intruded by Devonian adamellite and granodiorite. The igneous and metamorphic rocks form part of the folded eastern limb of the Green Mountain anticlinoriurn which lies 13 to 20 miles to the west. Five mappable units in the quadrangle are from oldest to youngest, Missisquoi, Shaw Mountain, Northfleld, Waits River arid Gile Mountain formations. The Waits River and Gile Mountain formations have been repeated by the Brownington syncline which extends from the Memphremagog quadrangle southeastward through the Plainfield quadrangle. Other folds in the quadrangle include the Wood bury syncline and the Nichols anticline. These folds were developed during the early stage of regional deformation and metamorphism in east-central Vermont and trend strhparallel to the axis of the Green Mountain anticlinorium.
