The dataset contains measurements of fractures and bedding at Le Biancane (geothermal field of Larderello-Travale, Tuscany, Italy) in the period May-June 2021. The term fractures in this dataset indicate a break in a rock where the orthogonal opening is predominant; when clear lateral displacement by shearing is observed, then we adopt the term fault accordingly to the definition by National Research Council (1996). The topological analysis has been conducted using the methods described by Sanderson and Nixon (2015; 2018). This dataset consists of two text files described below. structural-dataset.txt: this file contains the measured fractures and bedding planes, it is structured as follow: Column A is the Longitude of the point, datum WGS 1984; Column B is the Latitude of the point, datum WGS 1984; Column C is the dip direction of the measured structure; Column D is the dip of the measured structure; Column E is the type of the measured structure (fracture, fault, bedding) topological-analysis.txt: this file contains the measurement done for the topological analysis on nine sites at Le Biancane area, it is structured as follow: Column A is the code of the site; Column B is the Longitude of the point, datum WGS 1984; Column C is the Latitude of the point, datum WGS 1984; Column D is the number of nodes I (NI); Column E is the number of nodes Y (NY); Column F is the number of nodes X (NX); Column G is the percent of nodes I (%NI); Column H is the percent of nodes Y (%NY); Column I is the percent of nodes X (%NX); Column J is the probability of connection of nodes I-I (PII’); Column K is the probability of connection of nodes I-C (PIC’); Column L is the probability of connection of nodes C-C (PCC’); Column M is the radius in meter (r) of the circle used for the topological analysis; Column N is the value of the parameter CL; Column O is the value of the parameter CB; Column P is the area (m^2) of the circle; Column Q is the fracture intensity;
