Acton agates and friends - 4:51 PM, Mar. 31, 2008 |
The area just south of Acton and north of Vasquez Rocks contains volcanic layers from several million years ago. Within these volcanics are vugs filled with calcite and quartz, creating some very nice agate geodes. When I first took geology class at Pasadena City College, one of the field trips took us to Tick Canyon (I'm not sure if you can still go there), that used to be an evaporite mine. Above and below the evaporites are layers of volcanics filled with geodes. The geodes on my Dinosounds Isuzu Trooper are from the volcanics. Behind me is Erin Daniels and her mom Eileen.
