Silvermines Data
Silvermines datasets and models:
General notes and documents Silvermines. [SIL_iCRAG2017_NotesDocs.zip]
Surface grids of two horizons at the Silvermines deposit. These horizons are the base of the Waulsortian Limestone Fm and base of the Lower Dolomite unit. The Lower Dolomite unit is situated within the Ballysteen Fm. [SIL_iCRAG20170221_Surfaces_Drillholes_Images.zip]
Depth Contoured Maps of the horizons. [SIL_iCRAG20170221_Surfaces_Drillholes_Images.zip]
Drillhole databases for Silvermines. Drillhole database compiled and QA/QCed by iCRAG. This includes collars, survey, geology and assays. The database contains survey and geology information on 2522 drillholes in the Silvermines area in Co. Tipperary, including 46429 assays for Zn, Pb, Cu and Ag (21972 assay intervals). [SIL_iCRAG20170221_Surfaces_Drillholes_Images.zip]
Planar structural data in Silvermines digitized by iCRAG, with 595 fault planes, 562 bedding planes and 125 joint planes. [SIL_iCRAG2017_Digital_Orientation_Data.zip]
Digital georeferenced copies of historical paper copies for 73 Underground mine maps containing geological and geotechnical information, and 376 geological sections (N-S and E-W) in the Silvermines area. Warning: large dataset! [SIL_iCRAG2017_Sections_Plans_Rectified_and_Georeferenced.zip] and [SIL_iCRAG2017_Sections_Plans_Scanned.zip]
