These mineralizations are the result of the hydrothermalism phenomenon that is taking place following the diapirism present in this sector. This makes it possible to observe the intersections and the organization of the veins in 3D.
SGET EXTENSION TO SURPAC SOFTWARE
This software allows to model the extension of the veins by adapting the model according to the type of vein. This resulted in 3D models that were then used on the Surpac software. The outcrops presenting these vein structures were modeled by photogrammetry on Agisoft Photoscan. Indeed, according to tectonic indices, these mineralizations could have been established in the upper Eocene or also in the Miocene. However, the study of tectonics does not allow us to precisely date the mineralized veins.

Eygalayes is located in the continuation of this accident oriented N20. The study of tectonic indices made it possible to date lead and zinc mineralizations from the alpine compression of the Miocene. The first study area is affected by tectonic accidents, including a major oriented N20 with normal clearance and senestral component and dexterous replay. In this area, the mineralization found within the cenomanian facies is malachite and azurite. Concerning Eygalayes, it is a synclinal structure with facies ranging from Cretaceous to Eocene. At Orpierre and Les Cougnasses, the mineralisations found in the facies of the Bathonian/Bajocian and Aargau correspond to galena, sphalerite and cerussite. In Orpierre itself, former zinc mines were once exploited. The first zone corresponds to an anticline with predominantly Jurassic facies. Two areas are particularly studied: Orpierre and Les Cougnasses as well as Eygalayes. go to your toolspace and change the drop down from Active Drawing Settings View to Master View then just drag the style from your surface styles in your backup up to the drawing where you want it to be. This corresponds to the dauphinois domain of the Alps and more precisely to the domain of the Baronnies provençales. The areas studied are located between the French regions of Provence-Alpes-Côte-D'azur and Auvergne-Rhône-Alpes. This project is an introduction to research on the study of mineralized showings of lead, zinc and copper as well as their 3D modeling.
