Rock Classification

The Rock Classification tab is used to edit the default classification systems used in RSLog.

These Rock Classification definitions are sorted into the following categories:

• Slaking - the process in which earth materials disintegrate and crumble when exposed to moisture.
• Weathering - the physical (and sometimes chemical) decomposition of a rock due to exposure.
• Alteration - any change in the mineralogic composition of a rock brought about by physical or chemical means.
• Strength - Strength classification is based on the Unconfined Compressive Strength (UCS) of core specimens. When assessing strength, the geologist/engineer should be aware that you are estimating the intact strength (a sample of rock breaking along a defect provides an invalid strength estimate and the strength should be reassessed).
• Defects - defects are divided into several categories including: Type, Surface Shape, Roughness, Infill Type, Infill Thickness, and Infill Character.

To add/edit a default rock classification definition:

1. Go to the left-hand navigation menu and select Tools > Settings > Rock Classification.
2. Select the corresponding tabs for each classification system (Slaking, Weathering, Alteration, Strength, Defects) and adjust the default settings accordingly:
   1. Click + button from the toolbar located on top of the table.
   2. Enter the Symbol, Term, and Description once the dialog is prompted.
   3. Click Save button.
3. To edit a record, select the checkbox next to the record and click on Edit button from the toolbar.
4. If you want to ‘reset to default’, click the corresponding button.
