Shear zones (1:250,000)

dataset: SG_SHEAR_ZONE_250K
Shear zone areas. This dataset includes fault zones and shear zones defined during the Seamless Geology project (2006-2014). A shear zone is a zone of strong deformation (with a high strain rate) surrounded by rocks with a lower state of finite strain. It is characterised by a length to width ratio of more than 5:1.

Description
1. JOIN Database Connections\spivpro_geodata_p00402.sde\GEODATAVIC.SeamlessGeology\GEODATAVIC.SG_GeolStructure_250K_py with Database Connections\spivpro_geodata_p00402.sde\GEODATAVIC.SUMMARY_FAULT via SHEARDISPLACEMENTSTRUCTURE_ID 2. Output to R:\p_gsv\edit\seamless\database tables\Shear_zone_2017.gdb\SHEAR_ZN_250K location (all fields). 3. Load R:\p_gsv\edit\seamless\database tables\Shear_zone_2017.gdb\SG_SHEAR_ZONE_250K (final schema) with data from step 2. NAME=FORMATTED_NAME+"Zone", DESCRIPTION=TEXT_DESCRIPTION, OBSERVATION=INTERPRETATIONMETHOD1_CODE - other fields match 4. Create Database Connections\vsdl_ld_minerals.sde\MINERALS.SG_SHEAR_ZONE_250K and load features from step 3 - schemas identical Also copied here Database Connections\spivpro_gsv.sde\GSV.SG_SHEAR_ZONE_250K for Geoserver access (DEDJTR).
