need help creating an unconformity symbol

[LukeBailey]

I'm just starting out with ARCgis and am using it to digitise a geological map for my final year project. I've been trying to create a line symbol which looks like this [ATTACH=CONFIG]18776[/ATTACH]. Its not in the 'Geology24K' pack. Is there anywhere i can get one thats already been made?
Thanks.

I'm not aware of any other styles specific to geology.  I'm not sure if you've already reviewed this option, but you can create your own styles for symbology.  This can be done with point, line, or polygon symbologies.
