Prerequisites:

Fundamentals of structural Geology and stratigraphy (needed to work independently in the field), basic concepts on elaborations of geological mapping and sections. Basic skills of Geographic Information Systems.
It is necessary that the students have already followed and possibly sustained the Tectonics exam.

Objectives

Aim of this course is to provide skills on the most advanced techniques of Digital Field Mapping and 3D modelling, using softwares installed on GPS-integrated tablets or smartphones.
At the end of the course, the georeferenced data and images collected during didactic fieldworks, will be used to elaborate a 3D model of a deformed area of the Apennines.
After this guided group-work experience, students will be able to transform their original geological survey in any study area, in a 3D model integrating all the available subsurface data.

Contents

Use of appropriate softwares of geological mapping for collection of geo-referenced data, photographs, and information on outcrops; digital stratigraphic Logging; automatic plot of planar and linear structures;real-time structural analysis.
Upload of digitally mapped data in ArcGIS and MOVE Midland Valley software.
elaboration of geological maps and sections in ArcGIS and MOVE environment.
Elaboration of 3D geological models by integrating any available surface and subsurface data.

Extended Syllabus

Digital Geological mapping: potentiality, future perspectives, current limitations.
The choice of appropriate device (mobile phones and tablets) applications and operating systems (IOS and Android). Focus on the Midland valley Field-move software installed on Apple Ipad-Pro.
Introduction to FieldMove and ClinoMove; digital mapping workflows.
Perform a Geological Survey through a mobile device:
creation of Projects; import georeferenced topography, thematic maps and schemes (.mbtiles or georeferenced .tif); use of geological survey tools (digital fieldbook, graphic tools to edit photographs and draw sketches; digital compass; definitions of units -with associated colors- and structures -with associated symbols-; plot of planar and linear structures on stereonet).
Processing of field data and model building:
export a project and its data and import them into MOVE suite and in GIS environment;
interpolation of data and construction of a geological map and sections in ARC-GIS; import geological sections and map into a MOVE project; introduction to using Move; model building using maps and sections; integration with subsurface geophysical data; construction of 2D and 3Dmodels and updating of the models in real time;creation and display of attributes.
Development of Geological Models:
Validation techniques to improve geological models; restoration of geological blocks; sequential retro-deformation; forward modeling
Photogrammetric analysis of outcrops (optional - this didactic unit will be given only if the dedicated software will be made available by the department): introduction to photogrammetric software; image acquisition techniques; modeling and construction of three-dimensional outcrops; data analysis.

The Course will be given following a practical approach alternating frontal lectures in the classroom and fieldwork aimed at applying the studied techniques. Its didactic synthesis will be a multiday Field mapping in a deformed area of the Central Apennine thrust and fold belt aimed at collecting geological data and elaborating them in a project including a digital geological map, the associated sections and subsurface 3D model.

Contacts/More Information

At the beginning of the course, the teacher will schedule a weekly 3 hours reception-time, dedicated to the students.
Outside of this scheduled time, any receptions can be requested via email.
The teacher will work to guarantee students the maximum availability of the computerized room and the activation of supplementary didactics (tutoring).
