Mapping commingled magmas, Eastern Head of Isle Au Haut, Maine part of Cutting Edge:Geoscience in the Field:Activities
This is a week-long bedrock mapping project on Isle Au Haut, in Penobscot Bay, Maine, with three to four field days followed by 1-2 lab days. The bedrock is Silurian gabbro and granite that commingled in a magma chamber yielding hybrid magmas and spectacular examples of magmatic pillows and pipes that can be used to evaluate the fluid kinematics of the magma chamber. Students mapped intrusive contacts, collected GPS-located data on contact strike and dips and pipe trend and plunges, and finally made a map in ArcGIS.
Bedrock map of Cliff Island, Casco Bay, Maine part of Cutting Edge:GIS and Remote Sensing:Activities2
Dykstra Eusden, Bates College Summary Students collect gps locational and strike and dip data on a day-long fieldtrip to Cliff Island. The data is then used in ArcGIS to make a bedrock geologic map of the island. ...
ES/GE 217 Mapping and GIS part of Cutting Edge:GIS and Remote Sensing:Courses
This course focuses on learning the principles of GIS through extensive computer use of ArcGIS via examples from geology and environmental science. Lectures will supplement the laboratory component of the course. Students are introduced to cartography, common sources of geographic data, methods for collecting novel spatial data, and data quality. Finally, students learn to extend the capabilities of GIS software to tackle more advanced spatial analysis and data management tasks. Each student does an independent research project using GIS data.
