A road cutting in Tertiary basalt on the side of the road, near Addisons Creek, about 7km down the Lemonthyme Dam road. This is the same basalt containing the famous large zeolite-filled vesicles on Oliver’s Road.
Here, small vesicles produce specimens of chabazite, phillipsite, thomsonite, calcite and fluorapophyllite. In addition, a few specimens of analcime were found, the first time that this mineral has been reported from around Gads Hill. The habits of thomsonite here are interesting and unusual. The most common form is colourless to grey, yellow, or brown globular spherules with a pearly lustre. Less commonly, open aggregates of white or yellow flat bladed crystals occur, generally on phillipsite. There are also two rarer forms, the first as white curved wisps on globular thomsonite, and the second as white fibrous masses usually stretching across vesicles with fibres branching out in a number of directions. Both of these habits are reminiscent of some of the thomsonite from Jindivick, Victoria. Little fresh material is now available.
